CONTEXT ACQUISITION BASED ON LOAD SENSING

摘要

Methods and systems are described for sensing force information at a plurality of points on a continuous surface (20), and detecting contextual information about an object (42, 68) on the surface (20) based on the distribution of force on the surface. For example, a plurality of sensors (22, 24, 26, 28) may be included below different points on such a substantially continuous surface (20), where the sensors are operable to sense force information. Then, a processor (30) connected to the sensors (22, 24, 26, 28) may determine a location of the object (106) relative to the surface (20), based on the force information from the sensors (22, 24, 26, 28).
