Wearable computing device and human-computer interaction method

Abstract

The invention discloses a wearable computing device and a man-machine interaction method. The wearable computing device comprises a support, a head-mounted display, an eyeball shooting camera, a touchkey ring and a server, wherein the head-mounted display and the server are arranged on the bracket, the touch key ring is arranged on the head-mounted display, the eyeball shooting cameras are arranged on the head-mounted display, the server is respectively connected with the head-mounted display and the eyeball shooting cameras, the server is wirelessly connected with the touch key ring, and thenumber of the eyeball shooting cameras is two. According to the invention, a user can interact with the head-mounted display more naturally and accurately, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a wearable computing device and a method for human-computer interaction. Background technique [0002] Traditional human-computer interaction input devices (mice, keyboard caps, and touchscreens) are primarily designed for desktops, notebooks, and smartphones, and thus are not suitable for nascent wearable computing devices. At present, the display part of wearable computing devices is mainly head-mounted displays, including but not limited to AR, VR and MR glasses or head-mounted displays. The human-computer interaction methods used include: [0003] 1. Voice interaction is mainly to collect human voice information through a microphone, and input it to the wearable computing device as an operation command signal. The advantage of voice interaction is that it does not need to rely on human hands like keyboard, mouse and touch screen, and can realize human-computer inter...

AI Technical Summary

Problems solved by technology

The advantage of physical interaction is that it is suitable for complex information interaction, such as chart interaction and long text input, but the disadvantages are: (1) some serious occasions (such as meetings) are not suitable for waving hands in the air; One or two hands can complete the interaction process, which is no more hands-free than using a mobile phone

The advantage of gesture interaction is that it is similar to the touch screen operation of a mobile phone, and it is easier for ordinary people to adapt. The disadvantages are: (1) It is not intuitive enough. Touch screen interaction is what you see and you can touch it immediately. However, if you want to find the screen coordinates that your eyes are looking at in gesture interaction , requires hand-eye coordination and groping for a period of time to complete; (2) Similarly, gesture interaction must occupy one hand of the person to carry out

Brain wave interaction is still in the scientific research stage, with high bit error rate, low response rate, and poor stability, so it is not suitable for engineering practice

[0007] Due to their own defects, the above human-computer interaction methods cannot make people interact with the head-mounted display naturally and accurately, whether used alone or in combination, and thus cannot operate wearable computing devices efficiently.
