To add feel to the games, ultra sound is going to be used. The strength of the ultra sonic sounds are going to be used to create virtual objects in the mid- air.

This research is being intended at using mechanical arms or exo-skeleton to get connections. The greatest innovation is that, you will be able to use both hands for feeling and at the same time; multiple people will be able to enjoy the feeling.

The only limitation in this approach is on how much force to be produced in this manner and which in turn will limit the hardness of the virtual objects.
