TOMIHARI Ryuto (Miyashita Homei laboratory), a second-year student of the master’s course in the Frontier Media Science Program, Graduate School of Advanced Mathematical Sciences, received the Student Encouragement Award at the 205th Special Interest Group on Human-Computer Interaction, the Information Processing Society of Japan.
TOMIHARI gave an oral presentation titled "
Target Size Correction for Persons with Low Vision in Pointing" and was recognized for his excellent presentation.
The study focuses on the decrease in vision and the duration of mouse operation.
When you operate a mouse on a PC and click a button, the larger the button, the easier it is to select and the shorter the operation time. In addition, the shorter the distance between the cursor and the button, the shorter the movement and operation time. These factors are based on values determined by UI designers, and all users operate a mouse in the same conditions.
However, the operation time varies depending on the user even if a mouse is operated in the same conditions. For example, for people with low vision, buttons and cursors appear blurry, requiring careful operation and increased operation time.
The study verifies the prediction model of operation time considering the visual acuity of users.
It also verifies a model that corrects a decrease in vision by increasing targets (buttons and icons to be selected) in size. Use of this model enables operation in the same operation time even if the visual acuity deteriorates.
Then, the study suggests that the prediction model of operation time considering visual acuity could be used as a tool to correct UI according to the visual acuity of users.
