First Claim
1. A device comprising one or more motion sensors, a user interface, one or more processors, and one or more memory devices having computer-executable instructions embodied thereon, that, when executed, implement a method for generating and presenting adaptive activity alerts to a user, via the user interface, for promoting positive activity patterns for the user, the method comprising:
- receiving, from the one or more motion sensors, a first set of user-motion information over a first time interval, wherein the first set of user-motion information corresponds to motion of the user over the first time interval;
based on the received first set of user-motion information, determining a first level of variability of activity during the first time interval, wherein determining the first level of variability of activity comprises determining a power spectral density of the first set of user-motion information;
specifying a target threshold of activity variability, wherein the target threshold of activity variability comprises a target power spectral density;
comparing, in a first comparison, the target threshold of activity variability to the first level of variability of activity during the first time interval;
based on the first comparison, determining that the first level of variability of activity is less than the target threshold of activity variability;
based at least on the first level of variability of activity being less than the target threshold of activity variability, generating a pseudorandom value; and
based on the generated pseudorandom value, generating an activity alert and presenting the activity alert by way of the user interface on the device.

Abstract
Methods, computer systems, and computer readable media are provided for promoting positive activity patterns for users and facilitate long-term adherence to the activity patterns, such as by providing alerts or electronic reminders to ambulate in a fashion that is responsive to an individual'"'"'s actual activity patterns and behaviors and compatible with routine activities in the workplace and home. In particular, embodiments of the present invention are directed to measuring physical activity patterns during the waking hours of a human, and in some embodiments continuously measuring these activity patterns; automatically ascertaining whether the patterns exhibit sufficient frequency and variability of activity such as confers certain health benefits; and if the patterns do not manifest such features, to adaptively provide sensible reminders at irregular within-day intervals such as are likely to establish healthy patterns of ambulation and other light activity.
