Supporting the supermarket shopping experience through a context-aware shopping trolley

摘要

Shopping in supermarkets is becoming an increasingly interactive experience as stores integrate technologies to support shoppers. While shopping is an essential and routine type of consumer behaviour, emerging technologies posses the qualities to change our behaviour and patterns while shopping. This paper describes CAST - a context-aware shopping trolley designed to support the shopping activity in a supermarket through context-awareness and the acquiring of user attention. The design is based on understandings of supermarket shopping needs and behaviour derived from previous studies. The system supports customers in finding and purchasing products from a shopping list. A field evaluation showed that CAST affected the shopping behaviour and experience in more ways, e.g. more uniform behaviour in terms of product sequence collection, ease of finding products. However, they saved no significant time of the shopping activity.
