People are now familiar and even like multi touch and it’s time to think about what would be a next multi touch. One good way to getting an answer is to study HCI-related research works from SIGCHI, mobile CHI, IEEE tabletop conference, etc.
Among many cool touch UI research works, this post introduces an intriguing article entitled “New mobile UI with hand-grip recognition” found at SIGCHI2009 Video showcase . Unlike other multi touch interaction techniques, it takes a different way of applying multi touch technologies. The paper says the device recognizes how users hold a device to infer and provide what they want to do with it.
The proposed user interface is based on the assumption that the device can detect how a user holds the device. By analyzing the user's grip-pattern, the device recognizes the user's intention and adjusts itself to meet the specific needs of the user such as accessing an application. The concept of the user interface is presented through several use-case scenarios. In addition, the technical feasibility of the proposed interface is validated by implementing a working prototype system. 
The video clip includes several use-case scenarios and a prototype demo:
After googling, more detailed versions of the work were found [2-4]. Figure below illustrates the motivation, interaction concept, and technologies behind the work.

Of course, there are also many relevant research works. Graspable  and HandSense  are most similar works. Back-of-device interaction [7, 8], double-side interaction , sphere and curved interaction [10-13] are worthwhile to study.
