groupware workspace. These widgets include a miniature view, a radar view, a multiuser scrollbar, a glance function, and a “what you see is what I do ” view. The study examined the widgets’ information content, how easily people could interpret them, and whether they were useful or distracting. Observations

’s performance on two versions of a groupware interface. The interfaces used workspace miniatures to provide different levels of support for workspace awareness. The basic miniature showed information only about the local user, and the enhanced miniature showed the location and activity of others

We have developed a prototype miniaturized active vision system whose sensor architecture is based on a logarithmic structured space-variant pixel geometry. This system integrates a CCD sensor, mini pan-tilt actuator, controller, general purpose processor and display. Due to the ability of space

Recent advances in device miniaturization have clearly contributed to make Weiser’s vision of ubiquitous comput-ing closer to reality. However, such vision is still far from being accomplished because some difficult problems remain to be solved. It is still hard to develop applications that take

-Site (LESS) surgery, additional complexities are introduced. These complexities, including unintuitive controls, reduced dexterity, and limited workspace, hinder these methods from more widespread implementation in more complicated surgical procedures. Through the use of a miniature in vivo robotic surgical

and the performance requirements are considered. The designs of the fully prototyped haptic devices are compared through open-loop frequency response, closed loop force response, and tapping response in constrained motion. We emphasize the tradeoffs between key design factors including force capability, workspace

This paper presents a novel method for localizing miniature mobile robots (Scouts) using dynamic contours. An observer robot with a camera follows the miniature robot as it moves and jumps in the workspace. Dynamic contours are very effective in tracking the fast accelerations and decelerations

, and the resolution falls off gradually in the periphery. Our system integrates a miniature CCD-based camera, pan-tilt actuator, controller, general purpose processors and display. Due to the ability of space-variant sensors to cover large work-spaces, yet provide high acuity with an extremely small number of pixels

Viewports into large visual workspaces are sometimes supplemented by a separate window that displays a miniaturized overview of the entire workspace. Instead of this separate window, we have layered a transparent version of the overview atop the viewport. Because the overview fills the display

Abstract: The trend to miniaturization in the field of consumer and investment goods is leading to increasing interest in the field of precision assembly of small components. Until now most machines for precision assembly have been many orders of magnitude larger than the workpieces to be handled
