Design of multimodal instructional tutoring agents using augmented reality and smart learning objects

This demo presents a novel technique of enriching students’ learning experience in electronic engineering laboratories and the basis for its design. The system employs mobile augmented reality (AR) and physical smart objects that can be used in conjunction to assist students in laboratories. Such systems are capable of providing just-in-time information and sensing errors made while prototyping of specific electronic circuits. These systems can help reduce cognitive load of students in laboratories and bridge gaps between theory and practical applications that students face in laboratories. Two prototypes have been developed – (i) an intelligent breadboard prototype that can sense errors like loose wiring, wrong connections, etc. for a specific experiment, and, (ii) an AR application that provides visualization and instruction for circuit assembly and operating test equipment. The intelligent breadboard acts as a smart learning object. Design methods were used to conceptualize and build such systems. The idea is to merge practices of Human Computer Interaction with those of machine learning to design highly situated physically located tutoring systems for students. Such systems can help innovatively in teaching and learning in engineering laboratories.
