Motivation According to a report published for the Association for Computing Machinery's 1999 Computer. Human Interaction (CHI) Conference, people working on laptops with an external mouse are more than twice as productive, 48% to 58% faster, and made 42% to 53% fewer errors than those working with the laptop’s built-in touchpad or trackpoint 2/26/2021 Copyright © 2007 Pointex Incorporated 7

Motivation Cont How are we doing this? n Why? n Feasible? n Attempting to see if the camera technology can be used for purposes other than what it was designed for n 2/26/2021 Copyright © 2007 Pointex Incorporated 8

Alternative Design n Infrared LEDs mounted on the computer and user holding the camera ¨ Requires external camera ¨ Laptops have integrated web camera ¨ Heavier ¨ Uses more battery ¨ RF communication n 2/26/2021 Not suitable for airplane Copyright © 2007 Pointex Incorporated 13
