• Idea: Shape-changing shuttle:
• By changing the feather shape, air resistance can be changed.
• Usage Scenarios by changing the flying distance
• Adjusting the flying distance depending on the individual strength.

Proposal
Augmented sports by changing the flying distance of shuttle
Concept of our research Usage scenario
• Shuttle (18cm)
• Sixteen Strings
• A servo motor in the shuttle changes the opening status
5
Device: Shape Changing Shuttle
Principle of opening status Our proof-of-concept prototype
• Two experiments
• Experiment 1: Measure the distance depending the servomotor’s angles
• Experiment 2: Measure the distance by changing the opening status in the air
• Launching 10 times on each conditions
• Launching Device
• Unified distance by pulling to a set line
