It would be interesting to make scales that you simply place under the legs of a sofa, and they transmit the weight of those sitting there via Bluetooth. Based on the measurements, it could then be possible to determine who sat where and personalize the TV for the person sitting. Kind of like a box with N sensors, one for each leg. For a family of three or four, you can relatively accurately determine the weight. Well okay, unless they bring along a pack of cola, a bucket of chips, or corn, which would spoil everything. But actually, this is also a challenge: you could collect statistics for weeks and, over time, determine quite accurately even with cola and popcorn. This would make a cool startup 🙂
