Based on the suggestions and needs of local elderly services providers, we launched a companion doll specially designed for the elderly in Hong Kong. It can respond to touches and sounds to interact with users, and it also has a recording function. Their family can relay their messages to the elders through Abao. This product is suitable for long-term hospitalized elderly and patients with dementia. Using Bo, We hope to provide the elderly with opportunities to express their feelings, so as to stabilize their emotions and behaviors, and at the same time reduce the pressure on caregivers.
