The method used to display game information, either overlay or in-game, in first-person shooters, likely has a measurable impact on player performance. Quantitative research is needed in this area, as game designers are pushing for heads-up displays to be as minimal as possible. This is especially important for the smaller screens (such as tablets and even cellular devices), which are now being targeted...
Ambient Assisted Living (AAL) aims to improve the quality of daily life for all humans in different periods of life. Neural-Computer Interface (NCI) can be used within AAL environments to provide alternative communication means for impaired persons bypassing the need for speech and other motor activities. By monitoring, analyzing and responding to muscular activity (EMG signals) of users, NCI systems...
Paper presents an early concept of user interface component that is designed to help computer users to intuitively organise their digital storage, so that they can easily locate their previously saved documents. Instead of using traditional hierarchical folder tree, user is associating his documents with a pair of symbols, organized into three dimensional working space. Positions of user's hands are...
We present an augmented reality system that supports human workers in a rapidly changing production environment. By providing spatially registered information on the task directly in the user's field of view the system can guide the user through unfamiliar tasks (e.g. assembly of new products) and visualize information directly in the spatial context were it is relevant. In the first version we present...
A keyword-based query is not sufficient for retrieving presentations. We assume that episodic memories about authoring slides and giving a presentation can be used for query because users easily recall and recognize slides associated with such memories. In this study, we present slide retrieval based on research episode networks that are a network composed of slides, episodic information and the links...
The relation between visual motion information and temporal perception has a significant effect on the development of man-machine interface. However, the relation is still not fully understood. This study aims to investigate temporal processing of audiovisual simultaneity during perception of apparent motion, which is the fundamental unit of human motion perception. Participants performed an audiovisual...
The purpose of this study was to implement a web based application to provide the ability to rewind and review depth videos captured in hospital rooms to investigate the event chains that led to patient's fall at a specific time. In this research, Kinect depth images are being used to capture shadow-like images of the patient and their room to resolve concerns about patients' privacy. As a result...
In this paper we introduce PERCEPT-II, a low cost and user friendly indoor navigation system for blind and visually impaired users. Using an Android Smartphone that runs PERCEPT-II application with accessibility features, the blind user obtains navigation instructions to the chosen destination when touching specific landmarks tagged with Near Field Communication tags. The system was deployed and tested...
We propose a cross-media music retrieval system that provides its users with a toolkit for formulating their own query by describing their emotional requirements for changes in mood of music as a sequence of images. To interpret the query, the system uses a metric space to convert the color changes in images into continuous tonal changes in music, and vice versa. The system provides delta functions...
Providing the educational community with tools to analyze educational processes may result in a more effective education. Applying Data Mining techniques to educational data results in information on educational settings which, however, comprehend an extensive set of symbolic patterns that are usually difficult to understand. Visualization, due to its potential to display large quantities of data,...
We often encounter experimental results that are difficult to quantify although the visual recognition of a phenomenon is apparent. We are able to detect patterns and features with our vision that are complex to specify algorithmically. This is because our brain has evolved into a powerful pattern matching machine. One important class of measurement results in medical research are signals that describe...
In the past, several automatic video summarization systems had been proposed to generate video summary. However, a generic video summary that is generated based only on audio, visual and textual saliencies will not satisfy every user. This paper proposes a novel system for generating semantically meaningful personalized video summaries, which are tailored to the individual user's preferences over...
Programmers often need to backtrack, but backtracking support in modern programming environments is lim-ited. Previously, we have conducted a series of studies, which discovered that backtracking in programming is in fact prevalent and programmers need better backtracking tools. In this demon-stration, we will present our backtracking tool called AZURITE, which provides selective undo and history...
For the mobile platform, the generation of a user interface which has a stunning visual impact and a good experience is a hard work, because it requires at least two aspects: the content generation with three-dimensional condition and the complex logic editor. In this paper, an integrated development framework is proposed, which contains a graphics rendering engine, and several visual toolkits for...
Learning disabilities affect an increasing number of students. Among these disabilities, dysgraphia has a nonindifferent role since it undermines the writing communication abilities of the students, with side effects on their self-esteem and a great risk of reduced school performance and more difficult relationships with classmates. It is the opinion of many people that the right way to prevent students...
In the last few years, an ecosystem of devices and heterogeneous services has emerged with a huge variety of capacities and characteristics. These new devices, along with applications and services, must be used to enhance the quality of life, making the users daily activities easier, as well as increasing their personal autonomy. In this sense, there is a clear need for creating interfaces that adapt...
For the Internet of Things to be adopted in people's homes and at their workplaces, it is important to provide mechanisms that support them when controlling and monitoring smart things in their surroundings. We present the concept of user interface beaming, where the capabilities of different personal wearable computers are combined to allow users to conveniently interact with smart things in their...
In this paper, we present a new software developed to evaluate performance of background subtraction (BGS) methods in pixel-level and frame-level. To evaluate accuracy of diverse conventional BGS techniques, users first should select a BGS method, its fundamental parameters and test data set. Then, the software performs implemented analysis procedures to output qualitative and quantitative evaluation...
There is no Virtual Reality (VR) without immersion. It is responsible for giving the user a sense of presence in the virtual environment. The idea is to provide the user with the feeling of "being there"! In spite of recent advances, there are still VR applications that demand text (or other 2D) information for system control. In this case, current systems apply 2D graphical components to...
In the scenario of computational interfaces development, research efforts aim to offer new ways of interaction that are closer to the natural way in which humans interact with the real world. Amongst the diversity of interface modalities, the tabletop tangible interfaces make the link between physical and virtual objects, enabling to grasp and interact with their components in a physical manner, besides...
