Abstract. The wide availability of game based technologies and sophisticated e-Learning possibilities creates new demands and challenges on Human–Computer Interaction and Usability Engineering (HCI&UE). Solid research in HCI must support improvement in learning ability and creativity for both teachers and students. According to recent market surveys the Wii remote controller or Wiimote is currently more wide spread than standard Tablet PCs and is the most used computer input device worldwide. As a collection of many ...

An Holter open system was developed for collection, retrieval and management of data produced by commercial monitoring devices. It is based on four modules interconnected to form an integrated system: ECG analysis equipment, relational database, Java application for direct access to the DBMS, Web-script library for safe access to patient information (data consultation, extraction of summaries of lab activity and

Abstract. Data gloves are devices with a set of sensors for obtaining information about the movement of the hand and its fingers. In Virtual Reality, data gloves are widely used as input devices for its capability to interact with the computer for application development. Currently, there are many such devices, which are offered by specialized commercial companies at high costs. Nevertheless, in recent years low-cost solutions for construction and software development kits for data gloves have been available. This paper presents the design and development of a low-cost data glove system to be used in virtual reality applications based on finger movements. The design of the glove is presented as a prototype based on computer vision algorithms in order to determine the relative position of the fingers. The manufactured data glove requires only inexpensive materials and a simple webcam for motion tracking. In the performed tests, our solution shows good results in the task of tracking ...

ABSTRACT In this paper, we have developed a communication system for military based on hand gestures which will be useful for squad communication. In particular, we present an electronic soldier glove that employs wireless networks based on low-cost ZigBee technology, multi-functional sensors such as accelerometer and flex sensor based input device for collecting and classifying hand gestures. This system delivers data output through computer display. Experimental results have proved the success of the proposed hand gesture recognition system that can adapt to communicate with multimodal signals to enhance visual signal in difficult and stressful environments where visual communication may not be possible.

In most virtual reality applications, both three dimensional operation such as user navigation and object manipulation and text input such as programming, writing annotations and chat communication are important activities. However, most previous studies have proposed limited techniques for either text input or three dimensional operation. It is desirable to be able to directly operate a virtual object and input text in a virtual environment for working efficiency. In this paper, we propose a seamless input technique for user navigation and text input in an immersive virtual environment and develop an input device. The proposed input device can be attached on palms in order not to restrict hand motion. Our device enables a user to input text easily and speedily, because each button is assigned to each finger. Moreover, our device contains 6DOF trackers for three dimensional operation. Experimental results show that our prototype is faster to input text than existing methods.

Technological limitations on current interfaces have made researches to develop new devices to interact with objects in the virtual environment. The goal of this project is to develop and build a hands-free navigation system to be integrated into virtual environments. One of the most important fields in virtual reality (VR) research, is the development of systems that allow the user to interface with the virtual environment. The most intuitive method for moving through a virtual landscape is by walking. The implementation of a walking interface for a virtual reality system also allows a greater range of biomechanical experimentation and game research. Systems ranging from different platforms have already been implemented to produce virtual walking; however, these systems have been designed primarily for use with head mounted display systems. We believe that hands-free navigation, unlike the majority of navigation techniques based on hand motions, has the greatest potential for maxim...

To evaluate the potential of gaze input for game interaction, we used two tasks commonly found in video game control, target acquisition and target tracking, in a set of two experiments. In the first experiment, we compared the target acquisition and target tracking performance of two eye trackers with four other input devices. Gaze input had a similar performance to

We describe sensing techniques motivated by unique aspects of human-computer interaction with handheld devices in mobile settings. Special features of mobile interaction include changing orientation and position, changing venues, the use of computing as auxiliary to ...

We present a novel hardware device based on ferromagnetic sensing, capable of detecting the presence, position and deformation of any ferrous object placed on or near its surface. These objects can include ball bearings, magnets, iron filings, and soft malleable bladders filled with ferrofluid. Our technology can be used to build reconfigurable input devices – where the physical form of the input device can be assembled using combinations of such ferrous objects. This allows users to rapidly construct new forms of input device, such as a trackball-style device based on a single large ball bearing, tangible mixers based on a collection of sliders and buttons with ferrous components, and multitouch malleable surfaces using a ferrofluid bladder. We discuss the implementation of our technology, its strengths and limitations, and potential application scenarios. ACM Classification: H5.2 [Information interfaces and
