Learning System Using Cross Reality Technique for Physical Electronic Circuit Construction and Virtual Mid-Air Operations

Science and technology education necessitates teaching and learning experiments involving electronic circuit construction and measurements using experimental equipment. In this study, a novel cross reality system for learning physical circuit construction and performing virtual experiments using virtual experimental equipment with mid-air haptics is proposed. The proposed system possesses a technical novelty that enables a learner to operate virtual equipment with the same motions of his hand and fingers as the operations of the real equipment. An evaluation test using 150 patterns of virtual experiments verified the proposed system's effectiveness.
