Research on UX evaluation method of design concept under multi-modal experience scenario in the earlier design stages

User experience evaluation of design concept is of great significance to ensure predetermined design goals and to obtain feedback. Due to the fuzzy and dispersed design information in existing concept design views, complete experience information about the concept cannot be passed on to users during the process of concept evaluation in the earlier design stages. Against this background, firstly, an evaluation framework of design concept based on multi-modal and user-perceptible experience scenario was constructed, and the multi-modal expression mechanism and multi-sensory synergy arrangement principle of the design concept were also established. And then, specific generation method was given to have scattered concept views converted into the multi-modal and user-perceptible experience scenario. Finally, through a combination of semantic difference method, a multi-modal and scenario-based UX evaluation method of design concept in the earlier design stages was proposed in this paper, also a supporting prototype system was developed. The application of this method in the evaluation of ”high quality interior environment” concept showed that the multi-modal experience environment can effectively integrate the multi-views of design concept and improve the user’s perception depth of the design concept.
