Currently available computer usage monitors vary in design, simplicity and measures, making comparisons of data across studies difficult. Therefore, we propose a taxonomy of computer input device usage with the goal of capturing exposure parameters, productivity parameters and various patterns associated with computer work. The proposed taxonomy has a three-tier hierarchy, the topmost level being the computer interaction. The second tier contains three types of episodes: keying (where there is continuous interaction with the keyboard), pointing device (where there is continuous interaction with the pointing device) and idle (periods with no input device use). The third tier contains specific events within each type of interaction. For example, typing events include typing, number keying, number pad keying, function keys, screen navigation, backspace/delete (error rate), and chording (simultaneous multiple key depression). The episodes and event measures will provide an indication of duration and temporal patterns of work as well as an indication of the exposure to physical strain associated with the different types of interactions.
