Abstract: The present disclosure provides a wearable computing device including (i) one or more sensors, (ii) a partially or fully transparent display, and (iii) a control system. The control system is configured to receive data indicative of a three-dimensional model of a body part. The control system is further configured to receive sensor data from the one or more sensors. Based on the sensor data, the control system is further configured to determine a relative position of a physical body part of a physical body with respect to the wearable computing device. Based on the determined relative position, the control system is configured to cause the display to provide a hologram corresponding to at least a portion of the three-dimensional model of the body part such that the hologram appears overlaid onto at least a portion of the physical body part when viewed through the display.

Abstract: Systems and methods for using positions of detected, real object boundaries to enable user interaction with a virtual object are disclosed. A system can include one or more sensors or trackers configured to detect boundaries of a transparent, real object within a three-dimensional coordinate system. A computing device configured to track positions of the detected boundaries of the real object within the three-dimensional coordinate system. The computing device may also track a position of a virtual object within the three-dimensional coordinate system. The computing device may determine whether the position of the virtual object is within the positions of the detected boundaries of the real object. The computing device may also enable user interaction with the virtual object via user interface and receive input for interacting with the virtual object in response to determining that the position of the virtual object is within the positions of the detected boundaries.
