The StepWatchTM can record steps at one-minute intervals for up to six weeks, depending on the activity level of the user. The graph below shows step-per-minute (for one leg) plotted against time for a single day. In this case, the subject maintained a diary so that specific activities could be annotated. (In general, activity diaries are not recommended because they can influence subjects' behavior by focusing attention on activity decisions).

The StepWatchTM was designed to be minimally intrusive, provide no feedback to the wearer, and require no maintenance, so as to minimize impact on behavior. However, the StepWatchTM could also be used to motivate behavior if performance feedback was provided to subjects.

Graph shows steps per minute per time of day during activities such as jogging, walking to bus, to office, at work, errands, to home, and cooking
