Abstract: A hover touch controller device includes a touch sensor having a touch surface and a proximity sensor. The touch sensor provides two-dimensional position information on when and where a user's finger touches the touch surface. The proximity sensor provides three-dimensional position information on pre-touch events. The pre-touch events corresponding to the user's finger hovering over the touch surface within some maximum depth. The hover touch controller device further includes a processor. The processor determines from the three-dimensional information a hover point projected on the touch surface and determines from the two-dimensional information a touch point on the touch surface. The processor communicates the hover point and the contact point to a display device. This can include correcting for any perceived user interaction issues associated an offset between the hover point and the touch point.

Abstract: A bioelectrode including a plate, a first electrode disposed on a first side of the plate, and a second electrode disposed on the first side of the plate and separate from the first electrode. The bioelectrode further includes a first guard portion disposed on a second side of the plate, a second guard portion disposed on the second side of the plate and separate from the first guard portion, and a preamplifier configured to output a voltage signal based on a biosignal measured between the first electrode and the second electrode.
