Embodiment 1

[0041] Example 1, see figure 1 , 2 , choose the camera 4 as the sensor 1, choose the wearable computer for the computer 2 according to the needs, connect the camera 4 and the see-through head-mounted display (See-Through HMD) 3 to the computer 2 respectively through lines, and connect the computer 2 and the see-through The head-mounted display (See-Through HMD) 3 is connected to the video adapter 6, and a power supply module 7 is added to the computer 2 at the same time, so that the direction and range of the field of view of the camera 4 overlaps with the field of view of the user, forming a man-machine of the first method of the present invention interface device.

Embodiment 2

[0042] Embodiment 2, the same as Embodiment 1, the difference is that the electromagnetic tracker is selected as the sensor 1, and the electromagnetic field sensitive terminal of the electromagnetic tracker is worn on the user's head, and the relative position relationship with the user's head is fixed; A portable computer; forming a human-machine interface device for realizing the second method of the present invention.

[0043] According to the different sensors used, the realization method of this system is also different. Divided into the following two methods:

[0044] 1. Target object recognition method 1 (must have camera, computer, HMD)

[0045] The first method uses the camera as the sensor, and its working principle is as follows: figure 2 As shown; the video adapter is used to adapt the input signal of the HMD. If the computer can directly provide the video signal required by the HMD, the video adapter is not needed; the wearable computer is used as an example in...

Abstract

The invention discloses a man-machine interface device and method for achieving auxiliary information prompting based on regions of interest. The man-machine interface device is characterized by adopting a camera or an electromagnetic tracker as an input device and a perspective head-mounted display as an output device and aims at providing auxiliary prompting information for customers in real time. The achieving principle is that: firstly recognizing a target object (like aviation cockpit instruments) saw by a user currently, and then displaying the auxiliary prompting information corresponding to the target object on the miniature head-mounted display so as to achieve intelligent teaching, training or maintenance tasks. Manual operation of users are not needed when users carry out auxiliary information prompting, so that handless man-machine interaction can be achieved conveniently, intelligent teaching, training and maintenance tasks can be finished in aviation cockpits, vehicle cabs, workshop operation tables, operating rooms and the like, and the man-machine interface device and method can be used in fighter-pilot helmet aiming line measuring and the like.

Description

technical field : [0001] The present invention relates to the technical field of augmented reality and artificial intelligence, and specifically relates to a human-machine interface device and method for realizing auxiliary information prompt based on an area of ​​interest, respectively adopting a digital camera or an electromagnetic tracker as an input The display See-Through HMD is an output device whose goal is to provide auxiliary information to the user in real time. Background technique : [0002] With the development of virtual reality technology, augmented reality technology and artificial intelligence technology, computer-aided teaching, computer-aided training, computer-aided maintenance, and computer-aided manufacturing in the form of intelligent man-machine systems are gradually applied to industries including national defense, industry, education, Various fields including medicine and entertainment. In these man-machine systems, there are generally two proble...
