The researchers also asked participants a variety of questions to rate their "power usage," or level of expertise and comfort in using machines. This combination seems to make people more accepting of these technologies," said Sundar. They initiated online chat interactions with the various types of avatars to test the participants acceptance of those healthcare providers and their intentions to use those providers in the future.Researchers at Penn State University have claimed that people who have high confidence in machines and in their own technological capabilities are more likely to use and accept digital healthcare services. Some level of automation is clearly needed," he added."We found that the higher peoples beliefs were in the machine heuristic, the more positive their attitude was toward the agent and the greater their intention was to use the service in the future," said Sundar.Next, they exposed participants to various combinations of the healthcare provider, such as receptionist, nurse, and doctor; and agent types, such as human, avatar, and machine.The study was presented at the ACM Conference on Human Factors in Computing Systems in Glasgow, Scotland.According to Sundar, the healthcare industry can benefit from increased reliance on automated systems.The researchers recruited participants from the online workforce, Amazon Mechanical Turk, to gain a better understanding of user psychology behind the acceptance of automation in clinics A power user (a person with advanced computer skills) is more likely to accept a robot doctor, for example, than a non-power user," he added."We also found that power usage predicted acceptance of digital healthcare providers."In contrast, machines can be programmed to think of all the possible conditions that a patients symptoms could point to, and they never get tired.The team also noticed a double dose effect of machine heuristic and power usage."Doctors are limited by their human bandwidth, by their experience, knowledge and even state of mind from minute to minute," he said.First, the team gauged the participants preconceived beliefs about and attitudes toward machines - what is called a "machine heuristic".The team measured participants adherence to the machine heuristic by asking them to indicate their level of agreement with statements."We found that if you are high on machine heuristic and you are high on power usage, you have the most positive attitude toward automated healthcare providers."There is increasing use of automated systems in the medical field, where intake is now often conducted embroidery machines Wholesalers through a kiosk instead of by a receptionist," said S Shyam Sundar, one of the researchers, Penn State University."A machine heuristic involves stereotypes people have about machines, including their beliefs in machines infallibility, objectivity, and efficiency," said Sundar.
