Measuring the human


Although fingers and hands working keyboards, touchscreens, and mice may be the primary means of measuring human activity for human-computer interaction (HCI) studies, researchers have successfully used a variety of other sensors to act as input devices and to measurements of human responses. Eye-tracking tools are capable of measuring user attention and workload, as well as for acting as input devices, particularly with virtual reality and mobile devices. Sensors measuring body position and motion can be used both in games and to measure activity during tasks involving motion. Physiological measurements of skin conductance, heart rate, respiration, and even brain activity can provide insight into cognitive ...
