Here’s an interesting concept, it’s a tennis trainer that coaches you by acting as a virtual coach.
For one, as an experience embedded controller developer, you’d need some type of 3D accelerometer and lots of fun math calculations for the computer to figure out exactly how the tennis player is swinging then the virtual coach would tell the player to correct him/herself.
There, that’s my 2 cents for the engineering part, go make one!
Mana clips onto the player’s racket and calls our areas of the court for the player to run and take a fake shot. The product has three different vocal settings and three different weight variations to tailor for the needs of beginner, intermediate and advanced players.
