Study gauges preference for human-like or robotic faces
ATLANTA, Oct. 1 () -- People have varying opinions about what a personal robot should look like,[url=http://www.leedpe.com/]louboutin shoes sale[/url], and they change their minds based on what it is supposed to do, U.S. researchers say.In a study at the Georgia Institute of Technology, participants were shown photos of either robotic, human or mixed human-robot faces and asked to choose the one that they would prefer for a robot's appearance.While most college-age adults preferred a robotic appearance, nearly 60 percent of older adults said they would want a robot with a human face, and only 6 percent of older adults chose one with a mixed human-robot appearance, the study found."We found that participants, both younger and older, will assign emotional traits to a robot based on its face, which will determine what they are most comfortable interacting with," Akanksha Prakash, a School of Psychology graduate student who led the study, said.Preferences among both age groups wavered a bit when participants were told the robot was assisting with personal care, chores,[url=http://www.leedpe.com/]cheap christian louboutin shoes[/url], social interaction or for helping to make decisions, she said.For chores, the majority of older and younger participants chose a robot with a robotic face, but for decision-making tasks, such as getting advice for where to invest money, younger participants tended to select a mixed human-robot appearance, while older adults generally preferred a human face."Those who selected a mixed face perceived the robot as more intelligent, smarter or wiser than one with a 'cute' robotic face. Perceived intelligence in appearance was an important assessment criterion for receiving assistance with decision-making tasks," Prakash said. "As a result, preferences for robotic appearance varied across tasks."
