Abstract: This disclosure provides methods, devices, and systems for indicating an attentiveness of a user of a head-mounted display (HMD) device. The HMD device may include a camera configured to capture images of the surrounding environment, an electronic display configured to display the images captured by the camera, and one or more sensors configured to track a direction of gaze of the user. In some aspects, the HMD device may output an attention cue based on the images displayed on the electronic display and the user's direction of gaze. The attention cue may indicate an attentiveness of the user to a person or object in the surrounding environment. In some implementations, the attention cue may be output via an attention indicator disposed on an outer surface of the HMD device. In some other implementations, the attention cue may be output via a communication interface that communicates with another HMD device.

Abstract: Embodiments of the invention generally provide a method and apparatus that is configured to reduce the effects of interference that is undesirably provided to a transmitter signal that is delivered from a transmitter signal generating device to a sensor processor to determine if an input object is disposed within a touch sensing region of a touch sensing device. In one embodiment, the sensor processor includes a receiver channel that has circuitry that is configured to separately receive a transmitter signal delivered from a display processor and a sensor processor reference signal that is based on a display processor reference signal to reliably sense the presence of an object. Embodiments of the invention described herein thus provide an improved apparatus and method for reliably sensing the presence of an object by a touch sensing device.

Abstract: Display devices with improved routing between connectors and source drivers disposed on a substrate such as glass. Various features improve different characteristics of the routings between the connectors and source drivers. For example, a t-shaped connector is provided to ensure voltage provided to the source drivers is approximately equal. Routings may be tapered (i.e., altered in width) to reduce the amount of area consumption in locations where doing so is desirable but to decrease resistance in areas having more space. Routings may also include stacked power supply and ground traces to provide benefits such as improved decoupling capacitance. Other features are provided.

Abstract: An input device is configured to detect force being applied to an input region of the device by an input object, in addition to the position of the input object using touch sensing methods. Aspects include driving a force sensing electrode of the input device using an anti-guarding voltage alternating with a ground or guard voltage, while driving the touch sensing electrodes with a reference voltage, to obtain touch measurements, force measurements, interference measurements, double the force signal, and/o double the touch signal for differential touch and force detection. Aspects also include driving sensor electrodes using orthogonal signals and performing in-phase and quadrature demodulation of the received signal for simultaneous and independent touch and force measurements.

Each base sensor electrode is conductively paired with a base routing trace. The base sensor electrode and paired base routing trace have a size that is identical to a size of the paired sensing elements and conductive routing trace. The base routing trace terminates at the base sensor electrode to which the base routing trace is paired.
