Future developments for robotic companions for the elderly would most likely include the implementation of social and psychological aspects for the robot itself, as there is some evidence of elderly people unwilling to accept help electronically. The more human-like the robot is (in terms of conversation) the more enjoyable it will be for the user. However, this would require a lot of testing and design, as the robot would need to be socially intelligent, possibly recognize social cues and respond appropriately. There have been studies that show what the robot looks like correlates with its acceptance among humans as well as overall likability. While there are a multitude of robots currently in the works, most revolve around either cognitive rehabilitation, which are those that are more accustomed to helping with physical assistance, or social aspects, which are those that will have communication capacities. A study showed that, if given the choice, elderly people were more inclined to choose robots which were discrete and small, an example being PARO. In the same study, elderly people had been deterred from mechanical-looking robots, as they seemed like “children's toys”. Perhaps in the future, taking in this feedback from the elderly and integrating it into the design of robotic companions would allow for a higher acceptance rate.
