Robots will interact with us better if their eyes are soulful

Robots can be human-like, but lifeless eyes still make it easy to recognize it as a robot. And to make robots look more natural as well as research on communication between humans and machines, doctoral student Sean Andrist from the University of Wisconsin-Madison studied the vision of interacting with robots and he developed the The algorithm helps robots look at us at the right time and in the right way instead of the intimidating non-stop stare on human-like robots.

Why is the look and correlation between each person's eyesight and personality important? We all know two concepts of "extrovert" and "introvert". Extroverts will communicate more easily with extroverts. In the meantime, introverts often easily sympathize and share with other introverts or simply don't play with anyone. People of the same character when playing with each other are not only spiritually comfortable but also effective in many things, such as working together with higher productivity or better problem solving.

One of the most reliable ways to determine someone's personality or "direction" is a look . Extroverts tend to look at people when they are talking more than introverts. You may notice the look of an extrovert when talking to them even though you are looking away elsewhere.

People and robot clones.

If you are a human-like robot, you can use this data to interact more effectively with people. First, you can try using human eyes to determine whether they are introvert or extrovert and then you can adjust the look to match their gaze to make them feel feel more comfortable, thereby making them more effective when doing common tasks. The look is extremely important because "non-verbal behaviors, especially glances, have long been viewed as a useful scientific-social tool in persuading others to follow. request or suggestion ".

In a study published last year entitled "Look Like Me: Matching Robot Personality via Gaze to Increase Motivation," Andrist, along with two other researchers, Bilge Mutlu and Adriana Tapus tested many hypotheses related to Interoperability with adaptive gaze with the opposite person. The hypotheses included include:

• Combining the character of robots with human character will improve the proportion of people controlling emotions about robot performance;
• Combining the character of the robot with human character will improve the interaction efficiency with the requirements of the robot to perform a task in a longer time.

Participants were asked to play Tower of Hanoi Tower - a puzzle game in which you have to change the positions of circular discs mounted on 3 columns and match round discs to form a tower of size from Small to large, under the observation of robots and robots will also provide all the necessary gradations of game rules as well as the process of playing through many stages of the game. After initial instructions, the robot will carefully explain the game's goals and rules, and ask participants to complete the game. After the first successful completion, the robot will ask the player to do more and remind the player that they can decide to stop at any time if they wish.

The results are very interesting, according to Andrist's description: "Our first hypothesis predicts that participants can achieve a higher rate of emotional control with the performance of a robot with a personality that suits. they say, simply, the coordination between people and machines becomes more ".

This hypothesis somewhat reinforces the experiment in it: introverts say they like the behavior of robots more introverted. Meanwhile, participants who looked outwardly showed that there was no difference in the rate of emotional dominance. Introverts may be more sensitive to robot behavior and many previous studies have shown that they have a much higher awareness and awareness rate than extroverts. In addition, a study related to the rate of feelings of introverts with others also shows that introverts choose people with the same personality based on the "level of trust, honesty and morality " in when extroverts often contradict ideas when choosing you and often disobey these factors.

If you are a human-like robot, you can use this data to interact more effectively with people.

The experiment also reinforces the second hypothesis which predicts that players will be able to work well with robots that suit their personality. Based on measuring playing time, both extrovert and introverted people showed greater consensus with robots of the same character. However, if you measure the total number of plays and the number of disks moved to form the tower, the extrovert shows a greater consensus with robots of the same size as the introvert. Previous research on human communication - machines also showed similar results.

Andrist's research shows the interaction of sight between humans and robots to bring tangible effects, not just at human comfort or discomfort. For the ability to support socially as well as physically, glare is an important factor for robots to use tools to encourage people to complete tasks that will be very boring or repetitive. when they work with normal robots. This study was conducted with a group of participants and under certain conditions, so the researchers clearly understood that behavior and gesture behavior would be much more complex than their experiments. . In the future, they have planned to increase the detail and complexity of the vision models as well as experiment with more groups to find out who benefits the most from the support of robots.
