Have you seen PARO? Countless people were first introduced to PARO in an episode of the first season of “Master of None” starring Aziz Ansari. But is PARO a real thing? Is there a real robotic baby seal that’s cute, cuddly, and interactive? There sure is.
More About PARO
PARO is an adorable robotic baby harp seal that weighs about six pounds. PARO was developed in Japan by Takanori Shibata and is equipped with 32-bit processors, microphones, and several tactile sensors. To boot, PARO’s fur is fluffy and antibacterial.
PARO is a remarkable little gadget and able to recognize voices, track motions, and utter endearing little squeaks and whistles. It also remembers behaviors, has touch-sensitive whiskers, which help it interact with humans, and has a bunch of little motors that enable it to wiggle. In total, PARO has five types of sensors—light, tactile, auditory, temperature, and posture—that help it come to “life.”
PARO was built as a “pet alternative” and mainly intended for older people who desire company. A real pet can scratch or bite whereas all PARO places in its mouth is a pacifier it uses to recharge. If interested in seeing PARO in action, there’s a Youtube video of the little guy.
Although PARO has been sold in its native Japan and countries like Denmark for years, it really started to make headlines after it was introduced stateside. In fact, PARO was featured on Aziz Ansari’s new Netflix series, “Master of None.” Currently, a number of American nursing homes have purchased PARO for use with their residents.
However, in order to be worth its $5,000 price tag, many believe that PARO must do more than act cute; it must also help people—particularly the elderly—feel better. In that vein, let’s look at the science supporting PARO’s use.
Does PARO Have Therapeutic Value?
In a 2014 study, researchers in Japan examined interactions between elderly nursing home residents with dementia and PARO as compared with these participants’ interactions with Lion, a stuffed toy lion. The sample is this study consisted of 19 patients with mild dementia and 11 patients with severe dementia. Here’s what these researchers found:
- Both participants with mild and severe dementia talked to PARO more than they talked to Lion.
- Both groups of people showed more positive emotion and laughed more frequently around PARO than around Lion.
- Participants with mild dementia were more likely to exhibit negative emotion with Lion than with PARO, suggesting less favorable interactions with a stuffed toy.
- Participants with severe dementia were more likely to exhibit neutral reactions with Lion than with PARO, also suggesting less connection with the stuffed toy.
- Members of the mild dementia group were more likely to interact with staff when Lion was around than when PARO was around, suggesting that PARO received more positive attention.
Ultimately, the researchers suggest that PARO could serve as an effective icebreaker and help nursing home staff better help older people with illness.
Similarly, Dutch researchers examining the use of PARO among elderly people found that PARO could serve as a useful therapeutic tool when caring for older people. Specifically, PARO could be employed as a user-centered intervention to increase the quality of care and quality of life among elderly people.
However, these Dutch researchers were careful to stress that PARO is merely an aid and not a replacement for actual care provided by human caregivers.
You’d probably think that a cuddly robotic seal-like PARO would have no detractors … think again. Apparently, some experts worry that PARO is being used as a surrogate for care, support, and companionship—roles that should be fulfilled by humans, not robots. Instead, these experts argue that the role of robots should be more utilitarian and help with activities of daily living. For instance, in Japan robots have long been used to help elderly people eat and move.
In sum, PARO is a cute and cuddly aide that appears to lift the spirits of those who engage it, including older people with dementia and other conditions. However, PARO is no substitute for human care and compassion. Instead, it’s a sort of social icebreaker and research supports its therapeutic value in this capacity. Unfortunately, PARO’s hefty price tag probably keeps it from being enjoyed by the general public. Furthermore, it’s unlikely we’ll see PARO populating the aisles of a big-box retailer. Nevertheless, it seems like PARO is a good investment for long-term care facilities.
