Rapid Aerial Building Investigation

Chih-Chun Lin David Debon Ulka Patil Akshay Yelmar

Problem Space

Design Scenario

• Fire alarm reported at a high rise apartment
• Target users

○ First Due Officer ○ Incident Commander

• Scene size-up - 360 walkaround

○ Are people in danger? ○ Where is the fire located and its size ○ What is the structure status?

• No visible sign of fire from the ground
• Building Intelligence

Current Options

• Helicopter

○ Costly to operate ○ Restricted airspace ○ Dangerous operating conditions ○ Slow to the scene

• Aerial Apparatus

○ Has a large footprint ○ Immobile once set ○ Limited view

• Drones?

Design Focus

• Perform Scene Size-up and Building

Investigation quickly

• Keep costs low
• Simplified controls to lessen training time

Ideation

10x10 sketches - devices

Foldable Wearable

Projector Gesture

Deciding the approach- Hand-held

• Portable
• Easy to grip
• Sturdy
• Weather proof

10x10 sketches - interface

Scenario/Storyboard

Takeaways from sketching/storyboarding

• Hand-held, portable device for emergency situation
• Physical buttons for easy operation
• Different camera modes to monitor various situation

Building the initial prototypes

Option A Option B Option C

Option A - front and back buttons

Zoom in/out Changing camera mode flight control Camera control Power on/fail safe Front buttons Back buttons

Option B - Voice control

camera control flight control

Option C - Voice and gesture control

Dial switch camera mode camera control

Evaluation

Multivariate user testing

Variants:

• 3 models

Participant details:

• Masters in HCI student
• Female
• 24 years old
• User is a beginner with drone controls

Tasks performed:

• Take off - Find the target - Detect Fire - Hover - Adjust Camera - Monitor Scenes

User testing Feedback on Physical device

• Chose the Option C

Camera controls were confused as flight controls Did not understand the hover button

User testing Feedback on Screens

User did not understand what ‘HD’ meant

• User required guidance in completing the tasks

User was not able to recognize the buttons for zoom User was not able to recognize the button for hover

Going ahead with the Option C

Self-walkthrough Feedback on Physical device

• Buttons required for Altitude, Flight Take off, Flight land and Record
• No need of the controls for flight
• The model needs to be more sturdy

Self-walkthrough Feedback on Screens

• No need of the screen buttons for flight take off and land
• Need information on wind speed, wind direction, heat and humidity
• No need of the screen zoom controls, voice and gesture commands

Final Design Direction

Final Prototype

Core functions

• Control video/thermal

imaging camera

• Adjustment and zoom
• Switching camera

modes

• Display mission-critical data

Camera adjustment and zoom

Tasks

• Assess fire from various angles

and viewpoints Joystick for adjusting camera view Slider for zoom

Switching camera modes

Tasks

• Look for people in danger
• Look for hotspots
• Assess size of the fire

Dial switch for camera modes

Monitoring the scene

Tasks

• View critical data
• Look for openings
• Monitor structural integrity

Mission-critical data Structural information

Why this design approach?

• Simple design > Avoids steep learning curve
• Portable solution
• Physical buttons
• Robust design (water/shock proof)
• Fail-safe options
• Scope for adding functionalities in future

Process

Materials

• Paper
• Cardboard
• Foam
• Plastic

Challenges faced

• Organizing the small components
• Drawing icons and labels by hand
• Size and placement of the buttons
• Hand-drawn wireframes

Learn Iterate
