If you want a simple and convenient handheld phone solution, think handE!

Our hand integrated cellular device, handE, will allow for easier text and calling communication. handE will enable a one hand controlled messaging interface by integrating a combination of flex and accelerometer sensors with a microcontroller. By reducing the "unpocket and unlock it" time needed for a traditional cellphone, handE provides a faster, easy to use, and accessible alternative while maintaining a secure platform.
