3. Shopperception maps out in-store shopping behavior

A system called Shopperception may bring key insights into in-store shopping behaviors for retailers.  The system places 3D sensors around store shelves that will track how people interact with products in real-time.  A heat map will also detect which products were picked up the most and which were avoided.  Data from Shopperception will allow brands to better assess how their products are performing and act in real-time to consumer shopping behavior at the point-of-sale.

Kids these days seem to spend a lot less time outside and more time inside playing with electronics.  The ibitz fitness trackers will help parents get kids off the sofa and away from smartphones, tablets, and TVs and encourage more physical activity.  The trackers can be synced with mobile devices to set activity levels for the day and monitor how much physical activity a child is getting.  The system allows parents to lock their children’s electronic devices, and kids can only unlock their devices if they meet the activity levels set by their parents.

5. Montaj takes mobile video editing to a new level

Another player in within mobile video editing has emerged to fight its way past YouTube Capture and Socialcam.  Montaj allows users to stitch together clips to make a video montage to share with friends.  The app forces users to break down videos into 5-second clips, stitch them together, apply filters and add music.  The cool part about it?  If you don’t feel like going through each individual process, just shake your phone and the app brings up new edits, filters, and music.  You can then fine tune your video from there.
