In order to evaluate the usability of a proposed device the designer must make assumptions about the behaviour of the user population. This paper addresses how user assumptions can be expressed mathematically so that they can be integrated with an abstract device model. Such an integrated model allows usability decisions to be made during the system design cycle. In particular we address the qu...

The design decision has been made to allow the transparent cube to be removed from its cradle, and thus to be completely independent. This gives the cube a beautiful aesthetic quality, as well as an interesting tactile one, but this design also makes things technically complex. The second part of the paper will look at light enhancement of the LEDs, and waveguide coupling from the backplane int...

A shared interactive display (e.g., a tabletop) provides a large space for collaborative interactions. However, a public display lacks a private space for accessing sensitive information. On the other hand, a mobile device offers a private display and a variety of modalities for personal applications, but it is limited by a small screen. We have developed a framework that supports fluid and sea...

We develop an electrothermal transport model for nanocomposite thin films based on self-consistent solution of drift-diffusion and Poisson equations for electrons coupled with diffusive transport of heat. This model is used to analyze the performance of an electronic display the pixels of which are controlled by carbon nanotube CNT network thin-film transistors TFTs . The effect of electrotherm...

This paper presents a haptic stylus interface with a built-in compact tactile display module and an impact module as well as empirical studies on Braille, button, and texture display. We describe preliminary evaluations verifying the tactile display's performance indicating that it can satisfactorily represent Braille numbers for both the normal and the blind. In order to prove haptic feedback ...

Experiments to measure user performance in 3-D object pointing using a field sequential stereoscopic display are described . First , huma.n performance in adjusting a random dot stereogram depth is measured to determine the possibility of pointing at a 3-D object. This experiment shows that the image displayed on the field sequential stereoscopic display can give enough depth information to its...

Tracking of a see-through head-mounted display is a necessary precondition for proper overlay of virtual data and real scenes within the display. In our contribution, the intention and technique for Intraoperative Presentation will be presented. Focus will be the tracking of the display device. We will illustrate and compare three different optical tracking approaches and the results achieved b...

In this paper, we present a mobile communication and display device that learns gesture and color information collected by the user. We introduce the design prototype of a display that combines multi-modal sensing, embedded adaptive algorithms and a flexible color display. We propose an approach to the exchange of inter-personal information through transient public interfaces.
