Bibo the Dancing Cup: Reminding People with Dementia to Drink.

We present the concept and technical realisation for a cup that moves and lights up so as to bring itself to the attention of a person with dementia, to trigger taking a sip as a response. The concept is aimed at people with dementia in home or resident care who still have the ability to act, but tend to mentally drift away and thus require external impulses and triggers. The cup moves and lights up in regular intervals if it has not been picked up recently. Once it is emptied, it alerts a caregiver to refill. Moreover, the degree or level of movement and light can be configured, depending on the person's needs and reactions. This paper describes the core idea and focuses on the technical aspects of building a prototype on Technology Readiness Level (TRL) 3.
