The robots that dementia caregivers want

Speed read
  • Caring for people with dementia is stressful and emotionally difficult
  • Many current technologies for caregivers focus on education rather than assistance
  • Collaborative process lets caregivers design robots with features that would help the most

Building robots that can help people with dementia has been a longtime goal for roboticists. Yet until now, no one has sought to survey informal caregivers, such as family members, about what characteristics and roles these robots should have.

<strong>In need of support.</strong> Family members of people with dementia provide 18 billion hours of unpaid care per year with little support and few resources. Could technology ease their burden?A team of scientists at the University of California San Diego (UC San Diego) attempted to address this by spending six months co-designing robots with family members, social workers, and other caregivers.

Researchers found that caregivers wanted the robots to fulfill two major roles: support positive moments shared by caregivers and their loved ones; and lessen caregivers' emotional stress by taking on difficult tasks, such as answering repeated questions and restricting unhealthy food.

"Caregivers conceived of robots not only managing difficult aspects of caregiving--but also for supporting joyful and fun activities," said Laurel Riek, UC San Diego professor of computer science.

Spouses or adult children provide 75 percent of the care for people with dementia. Thats equivalent to 15 million people in the US alone, providing 18 billion hours of unpaid care per year with little support and few resources.

Most technology designed to support caregivers only seeks to educate, rather than to reduce burden. Caregivers may have access to virtual support systems and connections to clinicians via smartphones or desktop computers, but again this focuses on education and not direct assistance.

Before building the robots, it is crucial to get caregivers' input so that the robots are well designed and actually useful.

"It is imperative researchers take a community-health focused approach to understanding stakeholders' perspectives prior to building the technology," Riek said. "Especially in healthcare robotics - one should not walk in with a technology hammer."

Half of the robots designed by caregivers were primarily focused on alleviating stress from the repetitive questions people with dementia ask. Caregivers also envisioned robots that could provide reminders of a person's daily schedule and tasks. They also designed robots to help with physical therapy and manage medications.

As dementia progressed, caregivers wanted robots to interact more with the person with dementia by helping with daily tasks and offering reminders. The robots that caregivers imagined acted as counselors and facilitators--and sometimes as the "bad guys" who could say "no" to the person with dementia.

The researchers are now using these initial low-tech prototypes to build high-tech prototypes that they plan to begin testing in homes over the next year.

Interviews and hands-on workshops

For the study, researchers led by Riek built relationships with three different dementia day care centers in San Diego County.

Panduro and computer science postdoc Hee Rin Lee. A total of 18 people participated in the research, including family members who acted as caregivers, social workers who led the day care centers, and geriatric nursing students.

In the workshops, the researchers gave caregivers a brief presentation about the types of technologies available today, including pet-like robots, cleaning robots, telepresence robots, smart speakers, and wearables.

The caregivers selected key problems and co-designed robots to tackle them. They also selected functions for the robots (such as playing games, reviewing photo albums, exercising, etc.) and a mode of interaction (e.g., voice commands and touch screens).

Caregivers designed their ideal robots to follow predetermined scenarios, including preventing a person with dementia from driving, getting them to bathe, or answering repetitive questions.

Robot characteristics

Based on the results of the design process, the researchers identified a number of characteristics and guidelines for robots to support dementia caregivers and people with dementia:<strong>Caregivers want robots</strong> to help with problems like repetitive questioning but also to enhance positive experiences like viewing photo albums.

  • Robots should help redirect conversations when repetitive questioning becomes burdensome

  • Robots should be integrated into everyday objects that people with dementia are already familiar with, or borrow features from those objects. For example, one caregiver wanted her husband to get messages through the TV, which he spends a lot of time watching.

  • Robots should be able to adapt to new situations and to the behavior of the person with dementia. This is particularly important because dementia is a progressive disease and each stage brings new challenges for caregivers.

  • Robots should be able to learn from end users, and customize and personalize their interaction and responses.

  • Robots should have human-like components. That is not to say that they should look human. Rather the machines could, for example, use a real human voice or face. "When caregivers wanted robots to take active roles in persuading people with dementia to do something, they designed robots with more human-like features," the researchers write.

  • Robots should interact with humans via voice activation—much like a smart speaker. More specifically, caregivers wanted the robots to use voices that their loved ones would be familiar with. Caregivers also wanted robots to be capable of facial recognition.
