A Preliminary Investigation of Human Augmentation for Inclusive Design Education: Exploring Left-Handed Experience Simulation Effects

Inclusive design requires empathy for users with diverse needs, yet designers often find it difficult to consider perspectives and needs they have not personally experienced. This study investigated whether simulating left-handedness through human augmentation could enhance design awareness and reduce unconscious bias. The “left-handed experience device,” a wearable robot that simulates left-handedness by mirroring right-handed movements, was developed. Engineering students were divided into three groups: (1) no information about left-handedness, (2) explanation of left-handedness, and (3) experiential learning using the device. Each group conducted product redesign tasks focusing on usability and inclusivity using everyday tools such as calipers and kitchen tools. Design outcomes were evaluated using a self-assessment rubric. The group that used the device (Group 3) demonstrated higher awareness and generated more inclusive and symmetrical designs. Participants also reported increased confidence and empathy toward minority users. These results suggest that human augmentation can serve as a valuable educational tool for fostering inclusive design thinking. While experiential learning was effective in raising awareness, sustainable behavioral change remains a challenge.
