Interview survey of sighting information turned out to be more accurate when compared with Avatar in VR environment

ByMarco Verch

When conducting a testimony about a situation witnessed by a human being in the past, it is better to look back on the incident in the VR (virtual reality) environment against the "avatar" computer created by the computer than to oppose the person, Research has made it clear that you can remember the situation.

This research was conducted by Donna Ann Taylor, a full-time lecturer at the Westminster University psychology department in London, and a research team by Professor Coral J. Dandau of the faculty. When I listen to the animation reproducing the imaginary car theft case in the subject 48 hours after hearing the situation, I will explain the situation to the actual person and the situation that the virtual character created by the computer wearing the VR headset " Avatar ", and investigated what kind of influence appears.

The VR environments prepared for the survey are as follows. One of the chairs placed on the side of the table One of the avatars simulating a human being on the listening side sits and looks back on the incident in the state of being immersed in the VR space as an avatar that is reproduced on the computer by the computer.


Avatars prepared are as follows. It seems that it may be made more realistic, but rather it is a miso that it is an avatar that looks like a facial expression does not come out finely.


In addition, the VR equipment used in the experiment is Oculus Rift, 3D sound is also used together. Subjects who participated in the experiment were 38 people from the age of 18 to 38 who were selected by SNS and word of mouth, with 12 men and 26 females. Of these, 20 randomly chosen people face real people, the remaining 18 people face avatars in the VR environment.

The graph showing the results of this survey is as follows. The three graphs "AtoA" on the left side of the graph listen to the avatar, and the breakdown of the graph is "total correct answer number", "total number of mistakes", "total number of stories" from the left It is. It has been revealed that the result of AtoA is more "total correct answer" than face-to-face listening "FtoF", conversely "fewer total misunderstandings" and "total number of stories" are less near FtoF In other words, it means "I can recall more correct memories, few mistakes, and few cases to create stories on my own."


Mr. Dando said about the result: "A witness when hearing an interview is distracted by social behavior, such as the expression of the face of the opponent, but it may cause less attention. Social behavior may have a negative impact on the testimony and the performance of memories, "not only purely withdrawing memory but also acting to respond to the opponent in front of you, your own memory has a bad influence We are told that there is a possibility to receive it.

Although the interview conducted this time was against the general public, for example, when the audience was a person with authority such as a police officer, the pressure that the witness felt became even bigger, It can be predicted that it will reach. Although this experiment was targeted to a limited number of subjects as 38 people, by further deepening research further, in addition to bringing about the truth of the more accurate incident than it is now, in addition to sinning without being able to endure the pressure of investigation It seems that it can be said to be a research result that makes us feel that it can be used to prevent false accidents that would admit it.
