Abstract

The invention discloses a head-mounted display device and an interaction method thereof, and the interaction method comprises the steps that a depth camera on the head-mounted display device collectsa hand depth image of a wearer of the head-mounted display device, and the hand comprises the fingers of the wearer; The hand depth image is processed; the spatial position of the finger of the weareris determined, the input key of the virtual keyboard touched by the finger currently is determined according to the spatial position of the finger and the spatial position of the virtual keyboard generated in the head-mounted display device, and the head-mounted display device executes interactive operation associated with the input key. The finger touch virtual keyboard interaction more conformsto the operation habit of a user, the accuracy of input operation is improved, the complexity of carrying interactive tools such as a handle is avoided, and the market competitiveness of a product isimproved.

Description

technical field [0001] The present invention relates to the technical field of head-mounted display devices, in particular to a head-mounted display device and an interaction method thereof. Background technique [0002] With the maturity of the technology, the depth camera has developed rapidly and has received widespread attention in the industry. There are more and more applications and researches on the depth perception scene based on the depth camera, such as the field of virtual reality, and the interaction of head-mounted display devices using virtual reality technology. Method is critical to the VR experience. [0003] At present, the interaction mode of the head-mounted display device is mostly realized through a handle or a touch screen. Handle interaction has the disadvantages of being bulky and inconvenient to carry around, while the interaction method of the touch screen is not intuitive, and the accuracy rate is not high, the hands cannot be moved freely, and ...
