| Abstract |
Computers are occasionally used outdoors and in connection with cold store work. Cold hands and fingers can limit data input, as studied here. Six input devices, including trackballs, pens, and a mouse were tested by 19 participants in a screen target acquisition task with two target sizes under two experimental conditions, i.e. with a warm and with a cold right hand. Data measured were acquisition times, number of errors, participant's preferences, and observed handling of the devices. Effects of device, target size, and temperature were significant. Learning and attempts to improve handgrip were confirmed. Large-enough targets, a thick pen, and a mouse make computer work practicable in the cold. Direct visual feedback shortened acquisition times by half a second. |
