The Effect of Multimodal Search Input Window Type on Cognitive Load: Number of Search Inputs and Presence of Visual Cue as Adjustment Effect; [멀티모달 검색 입력 창의 유형이 인지부하에 미치는 영향: 검색 입력 값의 개수, 시각적 단서의 유무를 중심으로]

초록

Background This study aims to examine whether the type of multimodal search input window affects cognitive load depending on the number of search input values and the presence or absence of visual cues, and to empirically verify multimodal search input methods that can improve usability. Methods The type of multimodal search input window was identified through case study analysis, and the factors affecting the cognitive load with the number of search input values and the presence or absence of visual cues were derived through literature research analysis. Next, the research results of a total of 242 questionnaire answers were empirically analyzed through experimental research through manipulation of each factor. Results The type of multimodal search input window affects the intrinsic, external, and overall cognitive load, and there were differences according to the number of search input values and the presence or absence of visual cues. The left and right scroll types were identified as the highest cognitive load regardless of the number of search values, and the display of visual cues helped to reduce the cognitive load. The up and down scroll types provide the most positive search experience when the search amount was small. In addition, the accordion type is suitable to use it with visual cues when the search amount is large. Conclusions The results of this study will help build a strategy that can reduce cognitive load according to the multi-modal search input window, and the visual terminal. In addition, the study is expected to provide practical direction for future companies, which is expected for present companies.
