A spatial position indication system includes an electronic pen, an indicated position detecting circuit, a spatial position detecting circuit, and a selecting circuit. The indicated position detecting circuit detects a position of the electronic pen at an input surface or a hover region over the input surface. The spatial position detecting circuit detects the position of the electronic pen in a spatial region including at least a part of the hover region separately from and independently of the indicated position detecting device circuit. Based on output from the indicated position detecting circuit and the spatial position detecting circuit, the selecting circuit performs selection control so as to use output from the indicated position detecting circuit or the spatial position detecting circuit according to a separation distance of the electronic pen from the input surface when a drawing image to be displayed on a display device is generated.

Internet of Things (“IoT”) appliances are gaining consumer traction, from smart thermostats to smart speakers. These devices generally have limited user interfaces, most often small buttons and touchscreens, or rely on voice control. Further, these devices know little about their surroundings—unaware of objects, people and activities around them. Consequently, interactions with these “smart” devices can be cumbersome and limited. The present invention presents an approach that enriches IoT experiences with rich touch and object sensing, offering a complementary input channel and increased contextual awareness. The present invention incorporates a range sensing technology into the computing devices, providing an expansive ad hoc plane of sensing just above the surface with which a device is associated. Additionally, the present invention can recognize and track a wide array of objects, including finger touches and hand gestures. The present invention can also track people and estimate which way they are facing.

The present disclosure relates to a triboresistive touch sensor capable of generating electric power by electrification and electrostatic induction, and thus sensing a touch position without a grid.

An electronic erasing device includes a casing, an erasing portion slidably attached to the casing and having a bottom surface and a side surface that extends from an outer edge of the bottom surface, both the bottom surface and at least a part of the side surface protruding from an end of the casing, and a position indicator including a core body and a pressure detector that detects a pressure applied to the core body, the position indicator outputting a position indication signal indicating an erasure position indicated by the core body and information indicating the pressure. The position indicator is included in the erasing portion and fixed inside the casing such that a tip portion of the core body is positioned away from an outer side of the bottom surface of the erasing portion and the applied pressure is transmitted to the core body.

An electronic device includes a display layer, a sensor layer disposed on the display layer, and a lower member that is disposed under the display layer and includes a first shielding layer. The sensor layer operates in a first touch mode for sensing a first input based on a capacitance change and a second touch mode for sensing a second input of an input device that is configured to emit a magnetic field, and the first shielding layer shields the magnetic field that is transmitted through the sensor layer.
