Computer Interaction

Dialogue in natural language is the most important communication method for the visually impaired. Therefore, the dialogue system is the main subsystem in the visually impaired navigation system. The purpose of the dialogue system is to understand the user’s intention, gradually establish context through multiple conversations, and finally provide an accurate destination for the navigation system. We use the knowledge graph as the basis of reasoning in the dialogue system, and then update the knowledge graph so that the system gradually conforms to the user’s background. Based on the experience of using the knowledge graph in the navigation system of the visually impaired, we expect that the same framework can be applied to more fields in order to improve the practicality of natural language dialogue in human–computer interaction.

This chapter shows how elements of gamification, i.e. game thinking and game mechanics, can be integrated into a collaborative navigation system for visually impaired persons in order encourage them to travel independently and thus improve their quality of life and self-confidence. The system supports independent navigation in unknown places by mediating help from another visually impaired person, who is familiar with the particular place. Our system utilizes a thermal user interface to introduce an additional communication channel and thus to increase the usability of the system. The system has been successfully enhanced by game elements and illustrates the potential of introducing game elements into these systems.
