Current surgical simulations that involve cutting with scissors lack display of forces "between the fingers" of the operator. The objective of this work is to develop a fast, realistic haptic rendering technique for scissor cutting that can be easily integrated into soft tissue models commonly used in surgical simulators. A virtual environment was created for combined graphic and haptic display...

The paper outlines a pilot test on the UCSB Wearable Computer developed in conjunction with Project Battuta. The UCSB Wearable incorporates geographic context information (location and orientation) to display an electronic digital map to a user via a Heads-Up Display (HUD). Features of the custom designed Geographic Referenced Graphic Environment (GEORGE) software allow the user to switch betwe...

The visualization of information is in many respects back in the stone age, or rather the text age. WIMP GUIs just place more text on the screen and search engines use their graphic bandwidth to display advertisements, but don’t help us to assimilate information faster. The snazzy engines tend to present 1D clusters in text (e.g. vivisimo.com) or add expensive 3D representations to display the ...

Tactation is the sensation perceived by the sense of touch. Kinesthetic information describes the relative positions and movements of body parts as well as muscular effort when touching and manipulating objects. Haptic perception involves both tactile perception through the skin and kinesthetic perception of the position and movement of the joints and muscles,through the skin of our fingers and...

Spectroscopy Laboratory, The Dow Chemical Company, Midland, Michigan, USA In December 1955 or thereabouts, the authors coupled a homemade gas chromatograph to a research time-of-flight mass spectrometer constructed by W. C. Wiley, I. H. McLaren, and D. B. Harrington. This unique gas chromatography/mass spectrometry (GC/MS) instrument generated mass spectra at a lo-kHz rate for display on an osc...

The financial resources once required to maintain multi-million dollar facilities dedicated solely to virtual reality applications are no longer an absolute necessity. The technology to develop and display multi-user, stereo 3D immersive environments is now available on the desktop. Personal computers and 3D game-specific graphic cards are now powerful enough to allow anyone with modern persona...

The fundamental drawback of current stereo and multi-view display techniques is the necessity to perform multi-pass rendering (one pass for each separate view) and subsequent image composition-andmasking for generating multi-stereo views. Thus the rendering time increases in general linearly with the number of rendered views. An increase in frame-rate can be achieved by sub-resolution rendering...

Small screen devices, also known as small-form-factor (SFF) devices including mobile phones and ultra mobile PCs are increasingly ubiquitous. Their uses includes gaming, navigation and interactive visualisation. SFF devices are, however, inherently limited by their physical characteristics for perception as well as limited processing and battery power. High-fidelity graphic systems have signifi...

While research supports the use of graphic data representations in interfaces and control systems, work in this area has focused on relatively small systems with a limited number of variables. This paper describes an approach to designing a visual application for a semiconductor manufacturing plant. This is a complex, large-scale system requiring a structured design methodology. First, using co...

This paper describes the implementation of a PIC microcontroller in a conventional laboratory-type electronic trainer. The work comprises software for the PIC and hardware for the software. The PIC controller uses an EasyPIC-6 board and includes a PC-interfaced programmer for the PIC chip. It has many external modules: 128 × 64 graphic LCD display, 2 × 16 LCD display, 4 × 4 keypad, and port exp...
