Order interface model for individuals with Down sydrome and emotion analysis

Individuals with Down syndrome should be adapted to society. As there are various projects to achieve this goal, one of them is establishing cafes where all waiters/waitresses are individuals with syndrome. The Down Cafe is the one of these cafes that is located in Istanbul, Turkey. In such cafes, some of the tasks are quite hard to be performed by individuals with Down syndrome, such as taking orders. The waiters/waitresses with Down syndrome need assistance by their voluntary mothers for such tasks, thus it is actually performed by their voluntary mothers. In this study, a novel user interface is modeled for individuals with Down syndrome to take orders. We then analyzed their emotion mode as they are using the prototype. The interface was tested with existing Down cafe aiters/aitresses and findings were reported. We concluded that using novel assistive user interfaces for people with disabilities, personal assistance by their voluntary caregivers can be minimized as self sufficiency and degree of rehabilitation improves.
