Title: "Design Multi-Modal Interaction Techniques for Flying Drone"
Mr. Yui Pan YAU
Flying drones have become common objects in our daily lives, serving a
multitude of purposes. Many of these purposes involve outdoor scenarios
where the user combines drone control with another activity. Traditional
interaction methods rely on physical or virtual joysticks that occupy both
hands, thus restricting drone usability.
In this thesis, we investigate the feasibility and usability of a minimal
and subtle human-to-drone interaction. We designed a one-handed
human-to-drone-interaction method leveraging three modalities: force,
touch, and IMU. After prototyping three different combinations of these
modalities on a smartphone, we evaluate them against the current
commercial standard through two user experiments. These experiments help
us to find the combination of modalities that strikes a compromise between
user performance, perceived task load, wrist rotation, and interaction
area size. Accordingly, we select a method that achieves faster task
completion times than the two-handed commercial baseline by 16.54% with
the merits of subtle user behaviors inside a small-size ring-form device
and implements this method within the ring-form device.
The last experiment involving 12 participants shows that the ring device
demonstrates better performance due to its small size and weight than the
same method implemented on a mobile phone. Furthermore, users unanimously
found the device more helpful in controlling a drone on mobile.
Our findings give significant design clues searching for subtle and
effective interaction through finger augmentation devices with drone
control The users with our prototypical system and a multi-modal on-finger
device can control a drone with subtle wrist rotation (pitch and roll
gestures) and unnoticeable thumb presses within a miniature-sized area.
