Covid-19 may spread through public facilities—
such as digital signage. Gaze-based touchless technology allows
digital signage to be accessed without touching the screen.
Previous works, however, merely focused on seamless interaction
without rigorous consideration of user interface development.
Here we report an implementation of Design Thinking—a user-
centered design method—in development of digital signage user
interface. We conducted a survey of over 200 participants
for categorizing important topics related with Covid-19. Next,
we defined and developed personas and user interface. The
interface was deployed in a touchless digital signage equipped
with a Tobii ET5 eye tracker. Finally, we evaluated the proposed
user interface design in a real-time experiment. We asked the
participants to complete two tasks through different modes
of button—fast (300 pixels/s) and slow (150 pixels/s) moving
button. Our experimental results show that the participants
achieved 96.88% of average Task Completion Rate for both
fast- and slow-moving button. Our study implies that the user-
centered design provides a reliable scientific method to develop
a more user-friendly interface. Even in a novel technology such
as touchless digital signage, appropriate user interface design
may provide enjoyable interaction between users and the digital
signage
