Apple and Microsoft file patents for touchless controls

[Archean]

Apple and Microsoft are involved in a new patent race over touchless gesture-controls. Recently released patent filings reveal new ways to control devices that do not involve physical contact. Microsoft describes waving one's hands to "draw" three-dimensional objects on a computer, while Apple's designs involve allowing users to "throw" content from one device to another.

Securing patent rights allows the firms to claim ownership of the technologies.
