Hello Bettina, This is a fascinating device and I can see how it could help decrease feelings of isolation. I would be interested to see if the device could lead participants through balance exercises to help with fall prevention. I know that for my 90 year old grandmother, one of her main practices for preventing falls is to do different balance exercises. It would be fascinating if there could be group classes led with other participants through the Skype function, or another function of the device. This would be a motivation to do the exercises as well as an opportunity for a participant to meet other people. I would also be interested to see if the technology used in the X-Box console for their dance games could be adopted to help teach participants how to improve their balance and make sure that they are doing the exercises correctly.
