Arduino Nano RF
Transmit data read from the sensor
to the receiver wirelessly via radio
frequency.
MPU-6050 Sensor
An inertial measurement unit
that detects acceleration and
rotation of the wrist.
Adjustable Straps
Accommodation of different wrist
sizes using Velcro.
LiPo Battery
Compact and lightweight battery
for powering the transmitter and
sensor while being rechargeable.
EVA Foam
A lightweight material that is easily
cut, carved and heat to form the
wristwear shape.
Max/MSP
Data is displayed using dotted graphs to
determine specific gestures for triggering
the various selectable audio samples. The
visuals can be designed for projection to
complement the experience besides
gestures.
Features
Arduino Nano RF
Acts as an receiver to receive the transmitted
data from the wristwear to be displayed on
the computer via USB.
LiPo Battery Charger
It charges the LiPo battery that is used to
powered the wristwear’s sensor and Arduino
Nano RF via USB 3.0 for multiple uses.
Downwards Movement
The first gesture is an abrupt top-down hand movement,
with fingers pointing to the floor. The acceleration of the
downward movement is used to trigger the audio sample.
Bass Boom
The first audio sample is a bass boom with a pitch drop effect.
The effect deepens the pitch of the bass boom automatically
when the sample is triggered and played over time. Once the
sample has finished playing, the effect will reset itself.
Gestural Controls
Rolling Movement
The second gesture is a rolling wrist movement, with a
certain angle of the rolling movement triggering the audio
sample. Then, the acceleration of the rolling movement is
used to determine the subtlety of the movement to control
the audio effect on the audio sample.
Strings
The second audio sample is a strings with a vibrato effect. The
intensity of the effect depends on the subtlety of the movements
once the audio sample is triggered. When the audio sample is not
played, the effect will be turned off.
Gestural Controls
Upwards Movement
The third gesture is a down-top hand movement, with
fingers pointing to the ceiling. The angle of the upward
movement is used to trigger the audio sample.
Female Vocal
The third audio sample is a female vocal with a chorus effect.
The effect can be manually adjusted by the user beforehand,
creating an illusion of multiple singers singing at once.
