This paper deals with the path-planning problem for mobile wheeled-or tracked-robot which
drive in 2.5-D environments, where the traversable surface is usually considered as a 2-D …

This paper introduces a novel touch sensing system for a projected screen with a single
camera. To achieve touch sensing with camera image, there are two challenges to …

A de Bruijn arrays code is a set of $ r\times s $ binary doubly-periodic arrays such that each
binary $ n\times m $ matrix is contained exactly once as a window in one of the arrays. Such …

Interactive whiteboards are used to make classroom teaching and discussion easier and are
used in all levels of educational classes, corporate conference rooms, coaching studios …

Touch screens have become increasingly popular and widely used in most human-
computer interfaces. As screen sizes have become larger for commercial use, the cost …

The de Bruijn torus (or grid) problem looks to find an n-by-m binary matrix in which every
possible j-by-k submatrix appears exactly once. The existence and construction of these …

In this paper, we propose a transmission method, analysis, and implementation of an
ultrasound touchscreen system based on Lamb waves. The basic principle of this system is …

This paper presents the Home Interactive Interface (HIC), a ubiquitous projected GUI
providing the dwellers of a Smart Home with an instrument for controlling appliances …

In this paper, we propose a tabletop interface in which a user wears a projector with a depth
camera on his or her head and can perform touch operations on an image projected on a flat …

A robust positioning pattern is a large array that allows a mobile device to locate its position
by reading a possibly corrupted small window around it. In this paper, we provide …
