Offenders with psychological problems are to be helped with a new virtual reality system that offers them treatment in a safe environment.
As geographic information systems (GIS) technology matures and develops sophisticated decision support applications, there is an increasing need to optimise human-computer interaction (HCI) aspects. Although further advances in graphic interface design and operator training are required, the principal challenge is now in the ergonomics of shared cognitive responsibility between operator and computer system. A sound and comprehensive theoretical framework is required to understand and develop this relationship. Mental modelling provides an appropriate psychological paradigm which may be applied through arranging appropriate levels of cognitive control, (modes of engagement), for GIS operations. The validation of such a theoretical model demands the use of appropriate research methodologies within a multi-disciplinary HCI in GIS research program. A substantial reference list is provided to assist research in this field.. ...

Improved human-like realism of computer opponents in racing or motion-related games is provided by using a mixture model to determine a dynamically prescribed racing line that the AI driver is to follow for a given segment of the race track. This dynamically prescribed racing line may vary from segment to segment and lap to lap, roughly following an ideal line with some variation. As such, the AI driver does not appear to statically follow the ideal line perfectly throughout the race. Instead, within each segment of the course, the AI drivers path may smoothly follow a probabilistically-determined racing line defined relative to at least one prescribed racing line.

Human-Computer Interaction (HCI) raises demand of convenience, endurance, responsiveness and naturalness. This paper describes a design of a compact wearable low-power HCI equipment applied to gesture recognition. System combines multi-mode sense signals: the vision sense signal and the motion sense signal, and the equipment is equipped with the depth camera and the motion sensor. The dimension (40 mm × 30 mm) and structure is compact and portable after tight integration. System is built on a module layered framework, which contributes to real-time collection (60 fps), process and transmission via synchronous confusion with asynchronous concurrent collection and wireless Blue 4.0 transmission. To minimize equipments energy consumption, system makes use of low-power components, managing peripheral state dynamically, switching into idle mode intelligently, pulse-width modulation (PWM) of the NIR LEDs of the depth camera and algorithm optimization by the motion sensor. To test this equipments ...
The HCII 2020 proceedings deal with current developments in human-computer interaction in general. The HCI thematic focus is on topics such as gesture-based interaction; speech, voice, conversation and emotions; multimodal interaction; and human robot interaction.
A key part of the book is its extensive development of applications and graphical illustrations, drawing on such fields as the physical sciences, macroeconomics, finance, business logistics management, and medicine. Despite such tremendous diversity of usage, in terms of applications and diagramming notations, the book classifies and organizes diagrams around six major themes: system topology; sequence and flow; hierarchy and classification; association; cause and effect; and logic reasoning. Readers will benefit from the authors discussion of how diagrams can be more than just a static picture or representation and how diagrams can be a central part of an intelligent user interface, meant to be manipulated and modified, and in some cases, utilized to infer solutions to difficult problems.. This book is ideal for many different types of readers: practitioners and researchers in AI and human-computer interaction; business and computing professionals; graphic designers and designers of graphical ...
An editing system has a graphical user interface that shows media/metadata and metadata/metadata relationships and allows a user to navigate a graph defined by these relationships. Using this graphical user interface, a user may determine, for example, which masterclips are used in a sequence, or which sequences are using those masterclips. Such information can be useful for many purposes. For example, by identifying all masterclips used in a sequence, the media files associated with these masterclips can be readily recaptured in a different format. The graphical user interface provides simple navigation of such relationships by using two panes. Each pane may receive and display indications of any media data or metadata object type defined in the problem domain. In an editing system, such object types may include objects such as projects, sequences, clips and media files. Each of the object types has bidirectional and many-to-many relationships defined with other object types and many relationships can
Globe Group, a company under the brand Greenworks Tools, is one of the industry leaders in battery-powered outdoor equipment, developing tools that deliver the performance of a gasoline-powered tool without the hassle and emissions associated with it. Gasoline-powered tools are still prevalent in the field of arboriculture where arborists work daily with chainsaws while performing tree felling and pruning.. Now a new type of chainsaw is in development by Globe Group which is characterized by its lightweight and large battery capacity, which brings extraordinary battery life. This feature is possible by redesigning the chainsaw to support an external battery, which is housed in a separate battery pack instead of placing the battery directly inside the tool. The aim of the project is to adapt and design the battery pack for arborists by using a user-centered design approach with focus on ergonomics. This is done by having a close cooperation with the arborists during the whole project, from ...

Biological exploration on genetic expression and protein synthesis in living organisms is used to discover causal and interactive relationships in biological processes. Current GeneChip microarray technology provides a platform to an- alyze up to 500,000 molecular reactions on a single chip, providing thousands of genetic and protein expression results per test. Using visualization tools and priori knowledge of genetic and protein interactions, visual networks are used to model and analyze the results. The virtual reality environment designed and implemented for this project provides visualization and data modeling tools commonly used in genetic ex- pression data analysis. The software processes normalized genetic profile data from microarray testing results and association information from protein-to- protein databases. The data is modeled using a network of nodes to represent data points and edges to show relationships. This information is visualized in virtual reality and modeled using force directed
Context. User Interfaces (UIs) intensively rely on event-driven programming: widgets send UI events, which capture users interactions, to dedicated objects called controllers. Controllers use several UI listeners that handle these events to produce UI commands. Objective. First, we reveal the presence of design smells in the code that describes and controls UIs. Second, we demonstrate that specific code analyses are necessary to analyze and refactor UI code, because of its coupling with the rest of the code. Method. We conducted an empirical study on four large Java Swing and SWT open-source software systems: Eclipse, JabRef, ArgouML, and FreeCol. We study to what extent the number of UI commands that a UI listener can produce has an impact on the change-and fault-proneness of the UI listener code. We develop a static code analysis for detecting UI commands in the code. Results. We identify a new type of design smell, called Blob listener that characterizes UI listeners that can produce more than two

Advanced light microscopy methods are key to many biological studies. Their ease of use depends, besides experimental aspects, on intuitive graphical user interfaces (GUI). The open-source software Micro-Manager offers a universal GUI for microscope control but requires implementing plugins to further tailor it to specific systems. However, GUIs are often tailored to a single system. Since even similar devices can have different Micro-Manager device properties, such as power percentage versus absolute power, directly transferring a GUI to another instrument usually requires changing the source-code. We developed Easier Micro-Manager User interface (EMU), a Micro-Manager plugin, to simplify building flexible and reconfigurable GUIs. EMU can be seamlessly used with the Java Swing library to create device-independent GUIs for Micro-Manager. Such GUIs are easily transferred to another microscope thanks to an intuitive configuration menu that includes mapping of the device properties to the GUI

In this study a within-subjects design was used. Each participant played both versions of the game: tilting user interface and walking user interface. The playing order was randomized. The tasks in the game were exactly the same in both versions.. 4.1 Participants. This study was executed as part of the Tampere University of Technologys User-centered design course in the beginning of 2015. The course is a part of the Masters Degree Programme in information technology.. Overall 45 students participated in the user experience study in which the two user interface solutions were compared. From these 45 students 9 were left out as they did not play both games or filled in the user experience questionnaires inadequately. Of the remaining 36 participants 12 were females and 24 males while the average age was 38.5 years. Even though primary end users of the game are school children of age 11-14, this study was conducted with university students. This was intentional as they should master the ...

To date, though, Virtual Reality devices have not been able to stimulate simultaneously all five senses with a high degree of realism. But with funding from the Engineering and Physical Sciences Research Council, scientists from the Universities of York and Warwick believe they have been able to pinpoint the necessary expertise to make this possible, in a project called
The first idea that often comes to mind about contrast is something black and white. In the absence of shades and multiple colors, monochrome image uses contrast as the main booster of expressive potential. And that works the same way in user interfaces. Even more, comparing to the pieces of art or photography, contrast not only influences the aestheticism but also has a significant impact on usability and navigability of the layout. Therefore, wise usage of contrast is the powerful method of making websites and apps user-friendly and easy to use.. Surely, it doesnt mean that only black-and-white UI is the most effective. It wouldnt be wise to get limited so much when users globally present such a diversity of wishes and needs. However, «black-and-white» testing, already mentioned in the previous part, is highly helpful. Designers should keep in mind that colorful interfaces can look different on different screens and resolutions. Moreover, low contrast can make the interface hard to use for ...

This thesis introduces a hierarchical model for unsupervised learning from naturalistic video sequences. The model is based on the principles of slowness and sparseness. Different approaches and implementations for these principles are discussed. A variety of neuron classes in the hippocampal formation of rodents and primates codes for different aspects of space surrounding the animal, including place cells, head direction cells, spatial view cells and grid cells. In the main part of this thesis, video sequences from a virtual reality environment are used for training the hierarchical model. The behavior of most known hippocampal neuron types coding for space are reproduced by this model. The type of representations generated by the model is mostly determined by the movement statistics of the simulated animal. The model approach is not limited to spatial coding. An application of the model to invariant object recognition is described, where artificial clusters of spheres or rendered fish are ...

From within the rendering program, we can then position and define the lights and cameras. Lights of various sorts make the now-textured surfaces visible with the proper reflectance and shadowing. Cameras are surrogate eyes--viewpoints corresponding to places from which higher resolution renderings can be generated; they are also helpful for studying the model from key angles or at important locations. We are still within a modeling and rendering program, so there is no free movement within the computer model, as there is in a virtual reality environment. However, within the rendering program, we can set up a path along which a camera can be set to move. We then set the speed that the camera moves along the path (akin to walking speed, for example) and the length in seconds that the camera should move. That tells the software how many individual frames it must render (which could easily number several hundred or thousand). The computer then begins to render each frame in sequence. When the ...
One disadvantage of the client/server computing model is the clients strong dependence on the server. A system and method are disclosed for enabling a client application to operate offline from the server. For each request, the client application registers a request entry with a scheduler, informing the scheduler of an associated application callback. The scheduler then invokes this application callback when a network connection is available for use, and the client application then sends the request to the server. Error recovery methods are described for requests that are sent to the server but for which no reply is received, and for other error scenarios. Some applications may maintain client-side caches to lookup information independently of the server. Synchronization entries may be registered with the scheduler for keeping the client-side cache in sync with the server-side master data.

There is a considerable body of research showing that eye contact is a key component of social interaction. Not only are people more aroused when they are looked at directly, but if you consistently look at the person you speak to, you will have much more social influence over that person than you would if you averted your gaze.. The problem arises when you address a group of people. How do you pick who to engage visually? Most public speakers are encouraged to look around the room, alternating eye contact with individuals in the audience. But theres no way to look at everyone at once - so some of your potential social influence will by necessity be lost.. Now, a team led by Jeremy Bailenson has figured out a way to get around that limitation. In a virtual reality environment, there is no need for the representations of other people to be consistent. Since each individuals virtual experience is generated separately, in a room full of people, each person could experience the phenomenon of ...

An aircraft user interface haptic feedback system includes a user interface, a position sensor, a cogless motor, and a control circuit. The user interface is movable to a position. The position sensor senses the position of the user interface and supplies a user interface position signal. The cogless motor is coupled to the user interface, and receives motor drive signals. The cogless motor, in response to the motor drive signals, supplies feedback force to the user interface. The control circuit receives at least the user interface position signal and a signal representative of the motor current and is operable, in response to at least these signals, to control the motor current supplied to the cogless motor using a non-trapezoidal motor commutation scheme.

Brain-Computer Interfacing (BCI) can be used for capturing brain signals and translating them into commands that allow humans to control (just by thinking) devices such as computers, robots, rehabilitation technology and virtual reality environments.. This experiment goes a step further and was conducted by Dr Christopher James from the Universitys Institute of Sound and Vibration Research. The aim was to expand the current limits of this technology and show that brain-to-brain (B2B) communication is possible.. Dr James comments: Whilst BCI is no longer a new thing and person to person communication via the nervous system was shown previously in work by Professor Kevin Warwick from the University of Reading, here we show, for the first time, true brain to brain interfacing. We have yet to grasp the full implications of this but there are various scenarios where B2B could be of benefit such as helping people with severe debilitating muscle wasting diseases, or with the so-called locked-in ...

Advent of Wide Area Networks (WAN) allowed the availability of distributed information (Network Information Retrieval tools, NIR) and the development of unprecedented communications between users (Computer Mediated Communication tools, CMC). Initially, CMC was asynchronous and based on electronic mail and newsgroups. From email, mailing lists and newsletter were soon derived, while newsgroups generated, shortly after, electronic fora. Synchronous communication were introduced through the set up of chat services. On this line, current multimedia teleconference systems were then set up. Virtual reality was first introduced by MUD (Multi-users Domain) systems, and especially by MOO (MUD Object-oriented). This line produced current virtual reality environment, like the emerging Second Life system ...

We propose to apply virtual reality technology to the design and implementation of Medical Robotic Interfaces. A system for human controlled, robotically performed surgery consists of two components: a master and a slave. The robotic slave device that performs the surgery on the patient, and a human interface master device that controls the robotic slave. The master/slave configuration essentially provides an interface between the surgeon and the patients anatomy. The interface maps the surgeons movements and senses to the instruments. The more accurate, efficient and intuitive the interface the better. A robotic system can potentially re-map the conventional surgical interface to increase accuracy, efficiency and intuitiveness. Virtual Reality technology applied to the master component can assist in the interface re-mapping by providing greater immersion as well as scaling of force and size. ...
Hello Mi Fans,Our brains communicate with electrical and chemical signaling, but scientists have discovered that light stimulation could hold potential keys to manipulating neuronal communication pathways that influence motor control, sensory perception, memory, neurochemical production, and mood -- or cellular virtual reality, as a report from the Journal of Cell Biology describes it. Whos Interested in Optogenetics?With the rollout of the White Houses $300 million BRAIN Initiative in 2013, interest in uncovering the secrets of the human brain has accelerated and now includes many government agencies, public/private partnerships, and universities.Dating back to at least 1971, optogenetic research has matured enough to gain the attention of organizations such as the NIH, DARPA and IARPA, who are exploring the role that light-sensitive cells could soon play in fields surrounding neurobiological, including physical and mental health, human-machine interfacing, and advancing artificial ...

When humans talk to each other they communicate in far greater ways than simply speaking. The way that they speak matters - their facial expressions, tone of voice and body language. Without these added cues, its much more difficult to communicate in speech or writing, as anyone who has experienced misunderstandings by email knows full well.

sources]. Researchers at Carnegie Mellons Human-Computer Interaction Institute (HCII) used a ceiling-mounted camera and projector to record room geometries, sense hand gestures, and project images on desired surfaces.. But Robert Xiao, an HCII doctoral student, says WorldKit doesnt require such an elaborate installation. Depth sensors are getting better and projectors just keep getting smaller. We envision an interactive light bulb-a miniaturized device that could be screwed into an ordinary light fixture and pointed or moved to wherever an interface is needed.. The system doesnt require prior calibration, automatically adjusting its sensing and image projection to the orientation of the chosen surface. Users can summon switches, message boards, indicator lights, and a variety of other interface designs from a menu. Ultimately, the WorldKit team anticipates that users will be able to custom design interfaces with gestures.. Xiao developed WorldKit with Scott Hudson, an HCII professor, and ...

N2 - Lots of evidence and guidelines recommended that stroke patients have to do the rehabilitation all the time, but in fact, the ratio of patients doing the rehabilitation is usually less than one third. In order to enhance the rehabilitation efficacy, we develop an innovative mixed-reality music rehabilitation (MR2) system, which is consisted of an MR goggle, inertial measurement unit sensors, and an EEG system. Several music contents with different levels are implemented into the MR system. While doing the rehabilitation task, our system can monitor patients both gait information and electroencephalographic (EEG) signals to understand the rehabilitation performance in both central and peripheral nervous systems. The ...

The objective of this proposal is to initiate research on how compassionate design activities can help develop engineering students self and social awareness. Engineers design solutions within complex contexts that often have broader social, political, economic, and environmental impact. However, research has shown a culture of disengagement in the professional formation of engineers. This culture of disengagement is one where engineers often separate the technical aspects of their work from the social context of the solution in an attempt to be impartial and objective in their decision making. Yet the complex social contexts in which engineers design are becoming more and more important as engineered solutions now have an expanding reach in our global society. To more fully engage engineering students in social contexts, the work of this proposal will challenge engineering students to be compassionate in their design work to develop solutions that address users fears, dignity, freedom, and ...

Smart spaces foster the development of natural and appropriate forms of human-computer interaction by taking advantage of home customization. The interaction potential of the Smart Home, which is a special type of smart space, is of particular interest in fields in which the acceptance of new technologies is limited and restrictive. The integration of smart home design patterns with sensitive solutions can increase user acceptance. In this paper, we present the main challenges that have been identified in the literature for the successful deployment of sensitive services (e.g., telemedicine and assistive services) in smart spaces and a software architecture that models the functionalities of a Smart Home platform that are required to maintain and support such sensitive services. This architecture emphasizes user interaction as a key concept to facilitate the acceptance of sensitive services by end-users and utilizes activity theory to support its innovative design. The application of activity theory to
Title: Application of Novel Virtual Reality Technologies in Neuroscience and Diagnosis of Neurodegenerative diseases. Abstract:. In the past decade, due to advancement of computing power, Virtual Reality (VR) experiments have gained much more popularity. A VR environment allows natural world emulation for different purposes by replicating real world tasks, such as navigation. Application of VR technologies has opened a new paradigm to test several theories on brain function. As an example, an interesting and challenging brain function is our spatial ability and the strategies used in navigation. Despite the magnitude of effort in the field, the nature of spatial models depicting what strategies healthy humans use is poorly understood, let alone the way these strategies deteriorate with aging and Alzheimers. The majority of studies examining human spatial memory have utilized non-navigable tasks, typically table-top tasks using standardized paper-and-pencil tests (i.e. MMSE, ADAS-cog, route ...
