System using a living body as a transmission medium
Abstract:
A system for enabling communication between a portable computing device and a stationary computer. A user may wear the portable computing device while simultaneously using a pointing device coupled to the stationary computing device. The pointing device may be, for example, a mouse coupled to the computer via a wired USB connection and operated on top of a mouse pad. The mouse may further include at least two electrodes. A first electrode may couple to the user's hand while moving the mouse on the mouse pad. The second electrode may be coupled to the mouse pad, which may include a conductive surface that contacts with the second electrode. These electrodes couple electronically to electrodes in the portable computing device, forming a bidirectional link for exchanging information between the two devices.
