Abstract: A head-mounted display device includes a display portion and a face-fitting frame. The face-fitting frame has flexibility and is partially connected to the display portion.

Abstract: An adjustable strap and a head mounted display device are provided. The adjustable strap includes a body, a sliding member, a limiting member, and an engaging member. The body has a slot section and a control section. The slot section has a slot and an engaging portion. The control section has a through hole. The slot section and the control section overlap. The sliding member and the limiting member pass through the slot and the through hole for connection. The engaging member and the control section pass through the slot for fixed connection. The sliding member and the limiting member are configured to slide between a first end and a second end of the through hole. When the sliding member and the limiting member are at the first end, the limiting member restricts an engaging end of the engaging member to be away from the engaging portion, such that the slot section and the control section are relatively slidable.

Abstract: Aspects of the technology relate to a cover (e.g., for a handheld electronic device). The cover may include a cover body configured for securement to a handheld electronic device and comprising an accessory attachment area, wherein the accessory attachment area includes a plurality of receivers, and wherein the accessory attachment area is configured for coupling with an accessory in at least one of a plurality of orientations. In some aspects, each receiver further includes a space recessed into the cover body that is bounded, at least partially, by a recess wall, wherein each receiver includes an engagement surface configured for abutting engagement with a projection associated with an accessory when the projection is disposed in a secured configuration within a respective space. An electrical device cover and various attachment devices are also provided.

Abstract: An immersive headset system includes a headset device and a displaying device. The headset device includes a pupillary sensor for determining an interpupillary distance value. The displaying device is communicated with the headset device. The displaying device includes a display panel for displaying an immersive content. The immersive content includes a right visual window and a left visual window. The right visual window and the left visual window are displayed synchronously at different positions on the display panel. When the displaying device receives the interpupillary distance value from the headset device, the right visual window and the left visual window of the immersive content are allocated by the displaying device according to the interpupillary distance value.

Abstract: A method for folding and extending an antenna structure capable of transmitting a WiGig band is provided. The method has the following steps: (1) mounting a WiGig module within a base; (2) pivotally arranging the antenna structure on the base; and (3) folding or extending the antenna structure relative to the base to correspondingly reduce or increase the antenna structure for transmitting and receiving a valid range of a wireless signal. The antenna structure has two body portions, and each of the two body portions has a pivoting end and a signal receiving end opposite to the pivoting end. Each of the pivoting ends is pivotally disposed on the base at a first specific angle with respect to a horizontal plane, and each of the signal receiving ends is inclined downward by a second specific angle with respect to the body portion and disposed away from the body portion.

Abstract: A head-mounted display device includes a front piece and an annular piece. The front piece is adapted for placing a display device. The annular piece includes a pair of compression portions and a pair of rotating portions. The pair of rotating portions are respectively located at two opposite ends of each of the pair of compression portions. The annular piece is connected to the front piece via the pair of compression portions. When the pair of compression portions are compressed toward the front piece, the pair of rotating portions are adapted to be rotated relative to the pair of compression portions by the pair of compression portions being compressed, and rotation directions of the pair of rotating portions are opposite to each other.
