Research on spatial cognition and blind
navigation suggests that a device aimed at helping blind people
to shop independently should provide the shopper with
effective interfaces to the locomotor and haptic spaces of the
supermarket. In this article, we argue that robots can act as
effective interfaces to haptic and locomotor spaces in modern
supermarkets.We also present the design and evaluation
of three product selection modalities—browsing, typing and
speech, which allow the blind shopper to select the desired
product from a repository of thousands of products.
