My friend Scott, also an Electrical Engineer, recently completed his capstone project at Northeastern University. It is a unique input device that bases its technology on electrostatics, a very cool subset of Electrical Engineering. Below is the video and a brief blurb about the product.
Utilizing the theory of electrostatics, we have designed a low-cost human-computer interface device that has the ability to track the position of a user’s hand in three dimensions. Physical contact is not required and the user does not need to hold a controller or attach markers to their body. To control the device, the user simply waves their hand above it in the air.
WOW!! Imagine what is possible with something like that. I can see its application for live multimedia stage production. Beautiful!
