Abstract: User interaction with a display is detected using at least two cameras whose intersecting FOVs define a three-dimensional hover zone within which user interactions can be imaged. Each camera substantially simultaneously acquires from its vantage point two-dimensional images of the user within the hover zone. Separately and collectively the image data is analyzed to identify therein a relatively few landmarks definable on the user. A substantially unambiguous correspondence is established between the same landmark on each acquired image, and as to those landmarks a three-dimensional reconstruction is made in a common coordinate system. This landmark identification and position information can be converted into a command causing the display to respond appropriately to a gesture made by the user. Advantageously size of the hover zone can far exceed size of the display, making the invention usable with smart phones as well as large size entertainment TVs.

Abstract: Negative pixel compensation to compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the device is disclosed. To do so, the device can switch to a configuration to measure the grounding condition of the touching object and use the measurement to compensate the touch output values. In the switched configuration, a first set of lines of the device can be switched between a coupling to a stimulation signal input to drive the device, a coupling to a capacitance signal output to output a signal indicative of the object's grounding condition, and a coupling to ground. A second set of lines of the device can be coupled to a touch signal output to output a signal indicative of the object's touch at the device. The grounding signal can be applied to the touch signal to compensate for the negative pixel effect.
