Multifunction in-vehicle information systems are becoming increasingly prevalent in cars. These systems typically use a centrally located display and a single control device to carry out a variety of operations including navigation, communications, entertainment, and climate control. Advantages of these systems include: conservation of dashboard space, improved styling, function integration and...

In this paper, we use the optical-type eye tracking system to control powered wheelchair. The userís eye movements are translated to screen position using the optical-type eye tracking system. The pupil-tracking goggles with a video CCD camera and a frame grabber analyzes a series of human pupil images when the user is gazing at the screen. A new calibration algorithm is then used to determine ...

Abstract Research on text comprehension in relation to the reading medium (paper or screen) has mainly involved undergraduate high school students. To advance current knowledge effects of medium, this longitudinal study focused beginner readers, specifically, role precursors first graders’ narrative and expository linear texts from paper computer screen. Working memory inference skills as cogni...

Background: The effective 3D manipulation, comprehension, and control of 3D objects on computers are well-established lasting problems, which include a display aspect, a control aspect, and a spatial coupling between control input and visual output aspect, which is a debatable issue. Most existing control interfaces are located in front of the display. This requires users to imagine that manipu...

For the visualization of dense sets of 3D lines, view-dependent approaches have been proposed to avoid the occlusion of important structures. Popular concepts consider global line selection based on line importance and screen-space occupancy, and opacity optimization to resolve locally the occlusion problem. In this work, we present a novel approach to improve the spatial perception and enable ...

This paper gives a brief idea of touch screen technology and its interfacing with a controller to control the speed of single phase induction motor. Here touch screen technology and Programmable System on Chip (PSOC) microcontroller concept is utilized which is less space consumption and easy to design. The aim of this paper is to have remote sensing and speed control of an AC motor.
