Abstract: A head-mounted display device may display a holographic element with a portable control device. Image data of a physical environment including the control device may be received and used to generate a three dimensional model of at least a portion of the environment. Using position information of the control device, a holographic element is displayed with the control device. Using the position information, it is determined that the control device is within a predetermined proximity of either a holographic object or a physical object. Based on determining that the control device is within the predetermined proximity, the displayed holographic element is modified.

Abstract: A headband is disclosed for supporting a head-worn device with a comfortable and non-intrusive fit. In examples, the headband includes first and second loops supporting the headband on a wearer's head, and an adjustment mechanism for tightening the first and second loops. The adjustment mechanism tightens down the loops to a desired fit, at which point further actuation of the adjustment mechanism has no effect on the loops.

Abstract: A head-worn assembly is disclosed including a head-worn device supported on a headband. The headband may include a first loop positioned around the head, and possibly a second loop affixed to the first loop and positioned over the head. Weight distribution and comfort of the head-worn assembly may be optimized by mounting the head-worn device at an approximate center (front to back) of the headband, and further balancing the weight of the head-worn device (front to back) over the mounting point. The weight distribution and comfort of the head-worn assembly may be further optimized by providing several user-customizable adjustments to the head-worn assembly.
