A fuzzy interaction scheme of mid-air gesture elicitation

摘要

In a virtual assembly scenario, a semantic model of mid-air gesture interaction is established through a user-defined elicitation experiment. Considering the spatial-temporal continuity of the gesture movement, a fuzzy interaction scheme of gesture segments is proposed based on Trie Tree and Levenshtein distance. The experiment result proves that this design can effectively alleviate the effect of missing input sequences and recognition errors. Moreover, it helps relieve the memory load for users by establishing a close correlation of input actions. (C) 2019 Elsevier Inc. All rights reserved.
