Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Fingerworks.com Content Pulled Ahead of Apple Tablet Announcement
Up until last week, Fingerworks.com retained photographs and details about their multi-touch keyboards and gesture pads they released for Macs years ago. In fact an old press release describes the benefits of their Multi-Touch system in a combination keyboard/touchpad:
The MacNTouch Gesture Keyboard is a complete user interface that serves as mouse, standard keyboard, and powerful multi-finger gesture interpreter. Mouse operations like point, click, drag, scroll, and zoom are combined seamlessly with touch-typing and multi-finger gesture everywhere on the MacNTouch's surface.
People are amazed by all the things a hand gesture user interface provides. We have a large number of easy- to-use gestures that cover just about every common computer operation. Users don't have to reach for hot-keys because gestures are faster and easier to do.
It's been widely expected that this sort of all purpose multi-touch interface will be offered in Apple's upcoming tablet. Wayne Westerman who was one of the founders of Fingerworks has since been the author of many multi-touch patent applications from Apple, including advanced gesturing implementations for Mac OS X.
