| Summary: | 'others') for all of these measures except arm volume. The and discomfort (body part discomfort survey), a specific away from zero and may be indicators of work load or fatigue. conjunction with a standing fatigue study. The rapid growth days. This study used physiological, performance, and devices (IBM Options mouse, Logitech Sensa mouse, Microsoft different from the mice. discomfort), while not showing strict statistical finger temperature, systolic and diastolic blood pressure, following measures showed statistical significance for following: finger tip temperature, hand temperature, forearm in the use of graphical user interfaces (GUI's) has caused an increase in the use of nonkeyboard input devices. Further, individual input devices: arm volume, all three presentation input device features survey and an overall ranking. The input devices, especially studying standing input device input devices. The physiological measures used included the Logitech Portable trackball, Glidepoint touch pad, and PC mouse 2.0, Logitech Trackman trackball, MicroSpeed trackball, other measures taken during the experiment (arm, hand, and performance and preference ratings often not significantly pressures, median nerve conduction velocity, and finger tip rest. The best trackball was the Logitech Trackman, with significance for input device types (mice, trackballs, and significance for the different devices, all indicated trends simple tracking test with three different target presentation speed tracking performance tests, the input device features speeds, Subjective measures included perceived levels of pain Stylus mouse pen) for two hours on each of two consecutive subjective measures to determine differences between the subjects (4 male and 4 female) used each of the eight input survey, and overall ranking. Further analysis showed temperature, arm volume, systolic and diastolic blood the limited amount of literature available on non-keyboard the other input devices in both performance and preference. There was, however, no one mouse clearly better than the This study compared eight non-keyboard input devices in Throughout the experiment, mice were shown to be superior to usage, has caused concern about the increased usage. Eight vibration sensitivity, nerve conduction time, and body part vibration sensitivity. The performance measure used was a |
