    Objective: The aim of this study is to investigate the effect of character size and font type on legibility of elderly in smart watch usage, and to suggest a design guideline for smart watch - dedicated for legibility enhancement of the elderly people. Background: As the elderly population increases, the demand for health care and relevant costs for elderly are increasing correspondingly. Hence, there have been researches to implement wearable device onto the health monitoring system for elderly. In such manner, smart watch is one of the wearables popularly studied. However, poor legibility due to the small display of smart watch is considered to be a problem for the elderly to fully use it. Thus, legibility should be improved to allow elderly to use the smart watch more conveniently. Method: The task of selecting a target stimulus within two simultaneously given stimuli on a smart watch display was given to participants. A total of 10 sets of stimuli was given, and they were in combination of single font size and type. All subjects performed the task for a total of 8 stimuli sets combining 4 font sizes and 2 font types. The dependent variable is the time to select stimulus and the error occurrence frequency: the number of interference stimulus chosen. Results and Conclusions: In Gothic type, there was no significant differences in recognition time between font sizes. However, in the case of Myung, 9pt, 10pt is better than 11pt, and 12pt. In the case of error frequency, it is shown that 10pt and 11pt results better compared to other two font sizes in case of Gothic. There was no difference in Myung. Application: The results of the study can be the useful guideline to improve legibility for the elderly.
