Washroom cleanliness is a key influence on our positive attitude towards public spaces. Recently, interactive technology has been introduced. While the role of physical cleanliness is obvious, interactive technology may affect the perception of cleanliness. This study investigates whether the most recent washroom service time displayed on a touchscreen influences the perception of washroom cleanliness. Participants leaving a washroom were asked to rate the cleanliness of the washroom. The touchscreen that showed the service time was visible for the experimental group and covered for the control group. Results showed that participants who noticed the most recent washroom service time in the experimental group perceived the washroom as cleaner than the control group. In addition, the touchscreen was preferred as an interface for washroom service request, compared with telephone calls and text messaging. The results suggest interactive technology has potential to enhance attitudes towards public space.
