Abstract: A communication device, method, and computer program product prompt correct face/eye positioning to enable perceived eye-to-eye contact of a user of a video capturing device with camera on a same device side as the viewable display device. A first communication device includes a first display device having a first graphical user interface (GUI). A first image capturing device of the first communication device has a field of view that captures a face of a first user viewing the first GUI. The first image capturing device generates a first image stream of the field of view. A controller of the communication device identifies a look target area of the first GUI proximate to the first image capturing device. The controller presents visual content on the first GUI within the look target area to prompt the first user viewing the first GUI to look towards the look target area.

Abstract: An electronic device includes a display and an image capture device electronically capturing one or more images of a subject performing an activity. A wireless communication device can electronically transmit the one or more images to a remote electronic device across a network after a Procrustes superimposition operation is performed to compare the subject to a standard. The wireless communication device can electronically receive one or more electronically altered images identifying differences between one or more standard reference locations situated at one or more predefined features of the standard performing the activity and one or more corresponding subject reference locations situated at one or more predefined features of the subject performing the activity. These electronically altered images can be presented on the display of the electronic device to provide corrective feedback to the subject as how to better perform the activity.

Abstract: A piece-wise linear (PWL) waveform generator includes a current generator that generates a reference current, an output capacitor across which an output voltage is developed to form a PWL waveform, charging and discharging current sources for charging/discharging the output capacitor based on the reference current, a clock-controlled switch network for controlling the charging/discharging of the output capacitor, and a feedback control loop that senses the output voltage and controls the current generator to vary the reference current based on the output voltage. A first switch controlled by a first clock signal periodically connects/disconnects a current source output to/from a load impedance and a second switch controlled by a second clock signal periodically connects/disconnects a capacitor to/from the current source while disconnected from the load impedance.

Abstract: In aspects of location correlation in a region, a mobile device implements a location module that determines a current location of the mobile device in a region within communication range of a radio system based on location data received in radio signals from the radio system. The location module determines region coordinates at the current location of the mobile device in the region. The location module can then associate the region coordinates at the current location of the mobile device in the region with pixel grid coordinates determined from a digital image view as captured by a camera system in the region, and generate a location mapping of the region based on the current location and subsequent locations of the mobile device in the region. The location mapping correlates the locations of the mobile device in the region based on the pixel grid coordinates at the respective locations.

Abstract: In aspects of visual mapping of geo-located tagged objects, a mobile device includes a mapping module that receives map data of a geo-fenced area from a controller device of the geo-fenced area. The mobile device can scan for wireless-enabled devices within a geo-fenced area, and receive a designation input of a tagged object that corresponds to one of the wireless-enabled devices. The mapping module is implemented to generate a visual mapping that displays a route from the mobile device to the tagged object based on the map data. The mapping module can receive object metadata about the tagged object as the mobile device approaches the tagged object along the route of the visual mapping, and a 3D visual representation of the tagged object is displayed based on a received 3D object model of the tagged object.

Abstract: In aspects of location correlation in a region based on signal strength indications, a mobile device implements a location module that determines a current location of the mobile device in a region within communication range of a first radio system based on location data received in radio signals from the first radio system. The location module determines received signal strength indication (RSSI) values from signals received from a second radio system at the current location of the mobile device. The location module can then associate the current location of the mobile device in the region with the RSSI values, and generate a location mapping of the region based on the current location and subsequent locations of the mobile device in the region. The location mapping correlates the locations of the mobile device in the region with the determined RSSI values at the respective locations.
