I have not purchased leap motion yet, but from the diagram leap motion seems to be a table top addition for PC or Mac. There is a head mount unit for the device which leads to my assumption that it may be able to be mounted to the TV and work though the PC input.
From this thread https://community.leapmotion.com/t/top-mounted-leap-motion/2940
It states that leap motion cannot be used as a top mounting device.
I would really hate to purchase this item and leave it on the floor with a USB extension cable, for use on my TV as a computer monitor.
Unless on the other hand, it works on the TV stand counter, with input to the TV. Will the range reach the big screen, or will this item only work on small screen PC monitors? Would I have to mount the item to my forehead, to use it on the big screen TV?
I hope to hear from you folks soon!
