Reference photo showing all screens. From the left Take Off, Home Screen, Angle Adjustment,
Drone Movements, Orientation Adjustment, Distance and Speed Adjustment.

HTA for the first main task your team tested
Task: Take off and move to other side of user. Increase the drones altitude then move to touch
wall.. Land drone.
1. Take off Drone
a. Press anywhere on screen
b. Wait for the drone to finish take off and stabilize
2. Increase drone altitude
a. Press drone angle button
b. Increase Angle

If drone not high enough press increase angle

c. Press back button
3. Change orientation
a. Press drone orientation button
b. Drag drone to correct orientation (in relation to user)
c. Press back button
4. Move to wall (outside of HTA control)
5. Land Drone
a. Press land button

HTA for the second main task your team tested
Task: Low speed, high distance, counterclockwise 360 degree panorama shot
1. Take off Drone
a. Press anywhere on screen
b. Wait for the drone to finish take off and stabilize
2. Counter clockwise movement
a. Press drone movement button
b. Press counterclockwise movement button
c. Press back button
3. Set parameters
a. Press distance and speed button
b. Increase distance

If drone not far enough away press increase distance

c. Decrease speed

If drone moving too fast press decrease speed

d. Press back button

Our team, Team Rocket, worked together to make many design changes to our
tracking-drone because of the last prototyping session, and I will detail them now. As you can
see in the figure we made the “back” buttons more consistent and intuitive than in the previous

prototyping session.
As a team, once we saw the finalized design, we agreed that the back buttons were hard to
interpret and we predicted that users would have a difficult time figuring out what the buttons
meant, what they did, and how to use them. We predicted correctly. The new and improved back
buttons successfully addressed this issue. Another improvement that we made you can see in

As you can see, we made changes to the representations of the different the movement patterns
to show relation to the user.. We found from the last prototyping session that users had a hard

time figuring out what the buttons and arrows meant, and that confusion was greatly reduced by
the changes that we made.
Task Performance:
In comparison to the last prototyping session, this prototyping session was a massive
success. Users were more easily able to decipher what different buttons and screens meant and
what their purposes were. We believe this is due to the redesigned icons being more visual and
some minor rearrangement in the screen flow. One change we will implement moving forward is
to add unobtrusive titles to screens so that users don’t have to guess what the different buttons do
and moving the speed to a slider format on the movements screen.

As shown in the figure there is no option to change the speed and so having to go back to the
home screen to access the speed the drone executes movements is non-intuitive and confusing
which was the biggest obstacle during testing.
Revision Plan:
As seen in the above question “Task Performance”, the addition of screen titles will be
one major improvement that we will implement moving forward. This will allow users to more
easily know what screen they are on and what the buttons on the screen do. Another thing we
discovered thanks to the second prototyping session is that it was not intuitive what certain
button icons did and what actions they performed. In order to combat this, we plan to make small
button-subtitles that would allow a user to read what each button does. Additionally, we will

implement an “info” screen that is accessible from any other screen that goes into detail on what
the functionalities of each button and icon on the current screen are and how to use them.
Our team spent a while thinking about how we could gamify our project. We found it
difficult initially because we didn’t think users would enjoy a gamified system - we assumed
users wanted it to work as intended with no additional features. We then realized that gamifying
our project could give users incentive to use the drone more often which could spread awareness,
making it more successful. Our idea to gamify our project is to add certain milestones that users
achieve after a certain amount of time, uses, or other things. For example, one milestone may be
“Congratulations! You have flown 100 feet in the air.” and another may be “Congratulations!
You are now a member of the 1% of users who have used this drone 1000 times!”. These
milestones may be translated into points that may be redeemed through an online store, for
example, and may be shared through social media.
