Abstract: A virtual reality (VR) controller includes a handle, a side housing, and a switch. The side housing has a fixed portion and a flexible portion. The fixed portion is fixed to the handle, and a contour of the side housing extending toward the handle conforms to a shape of a palm. The switch is disposed between the handle and the side housing. The flexible portion is deformed to trigger the switch when the handle and the side housing are held and a force is applied to the flexible portion relative to the handle. In other words, the flexible portion abutting against the palm is deformed to trigger the switch when the handle and the side housing are held and a force is applied, relative to the flexible portion, to one side of the handle far away from the flexible portion.

Abstract: A head-mounted display includes a wearing portion, a display body, a first strap, a second strap, an adjustment assembly, and a switching assembly.

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.
