Wireless sensing units, methods, systems, and processor-readable media for obtaining pressure data relating to one or more pressure locations of a surface area are described. A wireless sensing system includes a pressure monitoring device communicating with modular wireless smart floor tiles using RFID, either using an RFID reader or wireless network interface (e.g., 802.11). The tiles incorporate passive or active RFID tags. The tiles can be powered wirelessly, e.g. by a built-in piezoelectric power unit or by a wireless power source using magnetic resonance. A data capture circuit in each tile collects and saves the data for transmission to the floor pressure monitoring device. Various software applications can be enabled by the smart floor system, including fall detection and prediction, gesture input, intrusion detection, and user location tracking for smart home automation.

Wireless sensing units, systems, methods, and media

A touch input tool for interacting with a capacitive touchscreen display. The touch input tool includes a plurality of spaced apart conductive touchscreen touch elements arranged to simultaneously operatively engage a screen of the touchscreen display at a corresponding plurality of discrete respective touch locations.

Touch input tool and system

A method and system including sensing a touch event on a touchscreen display of an electronic device, and changing a display layout rendered on the touchscreen display in response to determining that the touch event matches a stylus shaft gesture that corresponds to interaction of the stylus shaft with the touchscreen display. The stylus shaft may be located between a first end and a second end of a stylus.
