Improving User Attention to Chatbots through a Controlled Intensity of Changes within the Interface

Abstract

Designing user interfaces requires the efficient management of elements that interact with the user and attract their attention. In the development of technologies supporting the development of chatbots, few studies have focused on the visual aspects of the interface. Changes in the chatbot area can be of different natures, such as increasing or decreasing the number of messages. Due to habituation (change blindness), messages delivered by chatbots may not be noticed. The main goal of the present study was to examine the impact of changes within the chatbot on user behaviour and the possibility of directing user attention to the chatbot area. This study showed that the intensity and types of changes within the chatbot can improve performance and successful message delivery to users.
