Therefore, this application provides first old man can carry out the VR online with other second old man that carry out the rehabilitation exercise, the second virtual personage after the behavioral configuration that corresponds the second old man is accomplished, map in virtual scene, first old man can see the second old man who is carrying out the same rehabilitation exercise through the simulation of virtual reality equipment, need not to remove the rehabilitation exercise equipment, under the circumstances that fully guarantees real experience and feels, further promote the interest that first old man carries out the rehabilitation exercise. When the rehabilitation exercise equipment is used for rehabilitation exercise, most first old people only move in situ, and when second virtual characters of a plurality of second old people need to be mapped, the mapping positions need to be reasonably determined on the basis of first relations between the second old people and the first old people and second relations between the second old people and other second old people; the first and second relationships may be preset by the user, for example: level 1 friends and level 2 friends, the higher the level, the more intimate, may also be determined by historical interaction conditions among the elderly, for example: the old often converses or interacts in a virtual scene historically, and the intimacy is higher; generally, the closer the first old person is, the closer the mapping position is to the first old person, and the closer the VR visual angle center instrument friend of the first old person is to the first old person.
In one embodiment, the online module obtains other second elderly people performing rehabilitation exercises that need to perform VR online, including:
when a first old man inputs a first other old man who the first old man wishes to perform VR online based on an input device arranged on a virtual reality device, if the first other old man is online, a first VR online invitation is sent to the first other old man, and if the first other old man accepts the first VR online invitation within a preset first time, the first other old man is taken as a second old man;
and/or the presence of a gas in the gas,
when a first old man receives a second VR online invitation sent by at least one second other old man and inputs an accepting instruction for accepting the second VR online invitation based on an input device in a first time, taking the corresponding second other old man as the second old man;
and/or the presence of a gas in the gas,
when the first old man inputs a random VR online instruction based on the input device, the first old man is randomly paired with a third old man which also inputs the random VR online instruction and serves as a second old man.
The working principle and the beneficial effects of the technical scheme are as follows:
there are 3 ways to add a second elderly who needs VR online: one is that the first elderly enter directly based on input devices, such as: the VR online is carried out with the XX, and the input equipment can be a voice collector and the like; the first old man accepts the VR on-line invitation sent by others; and thirdly, randomly pairing the first old man online. Guarantee that the old man can select to want other old man of VR online, also guarantee that the old man can invite the interdynamic with other old man, in addition, even do not want the online object of VR, the system also can pair on line, has further promoted the interest.
In one embodiment, the online module maps the second virtual character in the virtual scene based on a first relationship between the second elderly person and the first elderly person and a second relationship between the second elderly person and other second elderly persons, including:
determining a plurality of first mapping positions capable of carrying out virtual character mapping in a preset range around a first virtual character in a virtual scene;
obtaining the distance between the first mapping position and the first virtual character;
when the first relation is not empty and the second relation is empty, a second virtual character corresponding to a second old man is mapped on a first mapping position with a distance from small to large in sequence according to the intimacy of the first relation from large to small;
when the first relation is not empty and the second relation is not empty, determining whether other second old people having the second relation with the second old people also have the first relation with the first old people;
if yes, the second old and other second old having a second relationship with the second old are preferentially and adjacently mapped on the remaining second mapping positions with the distances from small to large in the first mapping positions in sequence according to the intimacy of the first relationship between the second old and the first old;
if not, the second old man and other second old people having a second relationship with the second old man are adjacently mapped on the remaining third mapping positions with the distances from small to large in the first mapping positions in sequence according to the intimacy of the first relationship between the second old man and the first old man from large to small;

when a plurality of second virtual characters of a second old man need to be mapped, the mapping conditions are divided into 3 types: in a first mapping situation, a second old person only has a first relationship with a first old person, and does not have a second relationship with other second old persons, which indicates that the second old person only needs to be close to the first old person, and the closer the intimacy of the first relationship is, the closer the second old person is to a first mapping position closer to the first old person; in the second mapping situation, the second old person has not only the first relationship with the first old person but also the second relationship with other second old persons, and at this time, the second old person needs to be subdivided into 2 situations: the method comprises the following steps that 1, other second old people having a second relation with the second old people also have a first relation with the first old people, and at the moment, the second old people are preferentially mapped on the rest second mapping positions to ensure that the second old people are adjacent to the first old people, so that when the second old people generate an interactive action, the first old people can be seen in a VR visual angle, and the closer the intimacy of the first relation is, the closer the first old people is; 2, other second old people who have a second relationship with the second old people do not have a first relationship with the first old people and belong to stranger relationships, so that the first old people are not necessarily required to be seen in a VR visual angle when the second old people and the first old people generate interactive actions by mapping the far left third mapping positions, and the closer the intimacy of the first relationship is, the closer the first old people is; in the third mapping situation, the second old man does not have the first relation with the first old man, belongs to stranger relation, and is randomly mapped on the remaining fourth mapping positions. The tradition all is that virtual character removes in virtual scene, and what is seen by virtual character just transmits for the VR user, and more fixed exercise equipment user realizes that virtual reality is not suitable for, according to the difference of relation, can guarantee to have different mapping overall arrangement in different old man's VR visual angle, and the most suitable old man of mapping overall arrangement in old man VR visual angle self and other old man's relation condition do not influence each other between the user, and is more intelligent.
