Little Bear – A Gaze Aware Learning Companion for Early Childhood Learners
No full textPart 7: DemonstrationsInternational audienceComputing devices such as mobile phones and tablet computers are increasingly used to support early childhood learning. Currently, touching the screen is the most common interaction technique on such devices. To augment the current interaction experience, overcome posture-related issues with tablet usage and promote novel ways of engagement, we propose gaze as an input modality in educational applications for early learners. In this demonstration, we present the Little Bear, a gaze aware pedagogical agent that tailors its verbal and non-verbal behaviour based on the visual attention of the child. We built an application using the Little Bear, to teach the names of everyday fruits and vegetables to young children. Our demonstration system shows the potential of gaze-based learning applications and the novel engagement possibility provided by gaze-aware pedagogical agents
Audvert: Using Spatial Audio to Gain a Sense of Place
No full textPart 1: Long and Short Papers (Continued)International audienceWe introduce Audvert – a system that facilitates serendipitous discovery and navigation through spatial audio; used to navigate and discover points of interest in large, unfamiliar indoor environments. Our main aim was to create a lightweight spatial audio display that can convey a sense of a place without complex point and select interactions. We conducted a preliminary study comparing two audio types to see which best suited sound localization and a study of Audvert used in a real world scenario. Our findings suggest that long continuous audio performs better than short intermittent audio for sound localisation. We also discover a change in behaviour when using the system, with a large percentage of users wanting to visit newly discovered shops after using the system. We discuss the findings and draw research conclusions
Gaze Awareness in Agent-Based Early-Childhood Learning Application
No full textPart 6: Interaction with ChildrenInternational audienceUse of technological devices for early childhood learning is increasing. Now, kindergarten and primary school children use interactive applications on mobile phones and tablet computers to support and complement classroom learning. With increase in cognitive technologies, there is further potential to make such applications more engaging by understanding the user context. In this paper, we present the Little Bear, a gaze aware pedagogical agent, that tailors its verbal and non-verbal behavior based on the visual attention of the child and employs means to reorient the attention of the child, when distracted from the learning activity. We used the Little Bear agent in a learning application to enable teaching the vocabulary of everyday fruits and vegetables. Our user-study (n = 12) with preschoolers shows that children interacted longer and showed improved short-term retention of the vocabulary using the gaze aware agent compared to a baseline touch-based application. Our results demonstrate the potential of gaze aware application design for early childhood learning
