Abstract: A system and method for sharing and manipulating digital content allows users an intuitive mechanism with which to interact with touchscreen devices. A provided device with short-range wireless connectivity can interact with a mobile device by providing physical contact points that can be moved or adjusted to interact with displayed content. A series of the physical contact points distributed about the perimeter of the provided device allows an application to collect data regarding the position and orientation of the provided device placed upon the screen of the mobile device. A second set of physical contact points, also made of conductive material, contains at least one individual contact point that functions as a capacitive ‘button’ when the user touches it. Upon placement of the provided device on the capacitive screen of a mobile device, real-time tracking of the changing touch patterns can provide a more intuitive interface for handling digital content.

Abstract: Aspects of the present disclosure are directed to a multi-sensor don/doff detection system for an artificial reality device headset. The multi-sensor don/doff detection system can use a combination of a proximity sensor, an inertial measurement unit (IMU), and an eye tracking/face tracking (ET/FT) unit to make these determinations. However, when both the ET/FT system and proximity sensor system are active, they can have system coexistence issues. Thus, only one of these systems can be used simultaneously. The multi-sensor don/doff detection system can more accurately identify don events by using input from the proximity sensor and the IMU. The multi-sensor don/doff detection system can also more accurately identify doff events by using input from the IMU and either A) the proximity sensor when the ET/FT system is disabled or B) the ET/FT system when the ET/FT system is enabled.

After processing for the pairing is completed, the pen periodically transmits the pen-pressure value, and, during a period before the processing for the pairing is completed, the pen transmits, instead of the pen-pressure value, a shortened pen-pressure value of high-order M bit(s) that are shorter than the N bits for the pen-pressure value.

Abstract: Embodiments of the present disclosure provide methods for implementing a mixed reality system with less power. In some examples, a passive state of the mixed reality system can have a GPU render predictable content that does not need to be processed by a CPU. In such examples, the predictable content can be identified and rendered by the GPU while the CPU is in a low-power mode. Accordingly, embodiments of the present disclosure provide benefits not available with conventional techniques because a CPU may consume more power than a corresponding GPU. In some examples, the passive state can take advantage of the fact that predictable content can be identified and rendered without the use of the CPU. In such examples, the passive state can render predictable content that does not need to be processed by the CPU.
