Laser pointers endanger the retina?!

by S. Stry, P. Hering
"... With the availability of low cost laser diodes in the visible range, laser pointers have become very popular in both the public and private sector. They are commonly designed for the use in lectures and demonstrations by persons from educational institutions and industry. But they have also become a ..."

Laser Pointer Interaction

by Dan R. Olsen Jr., Travis Nielsen , 2001
"... Group meetings and other non-desk situations require that people be able to interact at a distance from a display surface. This paper describes a technique using a laser pointer and a camera to accomplish just such interactions. Calibration techniques are given to synchronize the display and camera ..."

Laser Pointers as Collaborative Pointing Devices

by Ji-Young Oh, Wolfgang Stuerzlinger , 2002
"... Single Display Groupware (SDG) is a research area that focuses on providing collaborative computing environments. Traditionally, most hardware platforms for SDG support only one person interacting at any given time, which limits collaboration. In this paper, we present laser pointers as input device ..."

About Laser Pointers Recommendations for Laser Pointer Safety and Selection

by unknown authors
"... Laser pointers are completely safe when properly used as a visual or instructional aid. However, they can cause serious eye damage when used improperly. There have been enough documented injuries from laser pointers to trigger a warning from the Food and Drug Administration (FDA and Safety Notificat ..."

A Practical System for Laser Pointer

by Interaction On Large, Benjamin A. Ahlborn, Bernd Hamann, David Thompson, Oliver Staadt, Oliver Kreylos , 2005
"... Much work has been done on the development of laser pointers as interaction devices. Typically a camera captures images of a display surface and extracts a laser pointer dot location. This location is processed and used as a cursor position. While the current literature well explains such a system, ..."

Laser Pointers as Interaction Devices for Collaborative Pervasive Computing

by Andriy Pavlovych, Wolfgang Stuerzlinger - Center for Parallel Computing , 2004
"... We present a system that supports collaborative interactions for arbitrary environments. The system uses laser pointers as interaction devices and employs a video camera to detect where each laser pointer is pointing. Time-division multiplexing together with a wireless link affords discrimination ..."

Useful Parameters for the Design of Laser Pointer Interaction Techniques

by Choon Hong Peck , 2001
"... This paper reports on some fundamental parameters for the design of wall-based laser pointer interaction techniques. Ten users participated in this study and their laser points were tracked and recorded by a computer. The data collected were then processed and statistically analyzed to provide param ..."

Tracking Multiple Laser Pointers for Large Screen Interaction

by Florian Vogt, Justin Wong, Sidney Fels, Duncan Cavens - Ext. Abstracts UIST , 2003
"... We describe a new technique for tracking and identifying multiple laser pointers simultaneously in a large screen collaborative environment. Our method is based on using a video camera to track and decode the laser pointers. We use an asynchronous serial bit stream created by blinking the laser ligh ..."
