The Future of Activity Tracking


Published on

The world of activity tracking is changing. In the future, instead of tracking if you are moving, you'll track how and why you are moving.

There are numerous implications, including gaming, sports performance, performance art, robotics, rehab, ergonomics, patient monitoring, and more. There are 6 videos in this presentation.

Thanks for viewing; where do you think the future is headed?
