Interacting with the big screen
CHI '02 extended abstracts on Human factors in computing systems - CHI '02
In large screen projection environments, inexpensive wireless input devices can not match the performance of standard desktop interactive devices. We added buttons and a radio transmitter to a standard laser pointer to match the functionality of a standard mouse. User testing revealed that the device performed as well as a standard mouse and significantly better than standard presentation input devices. Devices that used visible laser light performed significantly better than those with invisible near-infrared lasers.doi:10.1145/506443.506542 dblp:conf/chi/CavensVFM02 fatcat:7un4gj656zhltgv5iuu7p46zj4
