"At the size of an iPad and integrating more than 20,000 sensors, the Sensel Morph translates the detail, speed, expression, and power of touch unlike any other input device available on the market. Because Sensel’s technology measures force, not capacitance, it can detect far more than just the fingers and stylus pens required with today’s capacitive screens and trackpads. Indeed, Morph can detect any object or tool, from a paintbrush to a palette knife, drumsticks, and more."

Providing multi-purposeness to input devices is an important step in increasing both usability and the sustainability of physical interfaces. The Sensel's concept demonstrates that people are interested in making devices that allow for an array of interactions and uses. This interests me because touch is vital to physical interfaces. Sensel's not only providing a flat surface to interact with but also interchangeable controls analogous to the tactile interaction with real world objects; it helps to bridge the gap between mind and application.
