Working in a cramped coach seat during a flight or controlling a distant PC while presenting in a large room pose different challenges, but they can both be addressed with the Air Mouse from Gyration. The mouse uses a 2.4 GHz RF link to connect to a PC up to 100 ft away. It senses movements in any direction without requiring a mouse pad or other surface, letting users in constrained areas hold the mouse in any position. STMicroelectronics’ MEMS 3-D motion sensors and 8-bit microcontrollers monitor movements. Identical technology is also used in a Music Remote for the home. It can transmit through walls.
