Tangible Music Interfaces • Increased accessibility • Sensory engagement • Group use and concurrent
use
Advances in DIY hardware • Laser cutting • 3D printing • Electronics platforms (e.g.
Arduino)

Physical sound generation using everyday objects

actuator
object / surface Drum Duino Actuator!Sound is generated through the physical impact of the push rod against an object. Each actuator is color-coded to correspond to one specific channel.
Select active channel!Stores previous channel’s pattern in memory when changing.
Beat: enabled!
Beat: disabled!
Change speed!
Pattern indicators!Displays stored pattern, blinks to indicate active position.
Control panel Shape mimics the visual language of a Djembe Drum. Allows users to interact with up to three solenoid actuators
Version 1!
Version 3!
Version 2!
Participants • Co-discovery (constructive
interaction) • Preadolescents from a
technology hobby club • 5 pairs of 2 children • Aged between 8 and 11.
Setup • Short demonstration • 10 minutes of free
exploration • Recreate familiar sounds
(clock, jackhammer) • General questions about
their experiences
Method
What happened… • The actuators were much
more captivating than the control panel.
• Only after exploring many surfaces and objects did they start to change the rhythm.
• Children prefer loud objects.
• All groups agreed: “it would be hard to make music, but with enough practice, it should be possible.”
Results
Group use • Concurrent use was
facilitated because of the separate actuators.
• Actuators can be programmed individually, but always stay in sync.
Discussion
Accessibility • Children had no trouble
playing and generating sounds.
• Low threshold of use!
Sensory Engagement • Noise generated can be
considered annoying. • … but fun to play with!
Future work • Focus on the actuators.
