Overhead transparencies and traditional slide projectors are increasingly giving way to electronic, computer-based presentations. Controlling these presentations remotely, as with a slide projector remote control, has recognized value. Examples include "GyroPoint" from Gyration, "RadioMouse Linkpro" from G-Tech, "Cordless MouseMan Wheel" from Logitech, and others. A tool commonly used in presentations in both new and old formats is a laser pointer. Laser pointers provide an intuitive and robust method for bringing audience attention to particular areas of a presentation, and are likely to remain popular presentation tools. By combining these two devices into a single unit, the presenter is saved the confusion of keeping track of which hand is holding which device, and the number of pieces of equipment required in a meeting room is reduced. The combination is facilitated by the fact that these two devices have similar power requirements, an similar user-interface requirements. An example implementation of a wireless mouse 1 with laser pointer is described in connection with Figure 1. The mouse 1 comprises a laser emitter 5, an infrared emitter 6 (if mouse does not use another medium, such as RF), a laser pointer activation button 7, a trackball 2, and two wireless mouse action buttons 3 and 4.
