QWERTYBeats:
an accessible
interface for
rhythm
Ethan Hein
Design for the Real World
Michelle, age 15
• Enjoys music, but has little experience participating
in it, and no formal training
• Has limited vision, along with some additional motor
and cognitive challenges
• Has access to internet-connected mobile devices
and/or desktop computers both in her
music classroom, and at home
Goals:
• Enable her to jam in class
• Help her explore rhythmic ideas that she can transfer
to hand percussion or other instruments later
• Enable her to make music without disturbing other
family members
Cognitive skills required:
▪ Memory and attention
▪ Enough motor skill to find particular keys - precise
timing not necessary
User persona:
high-functioning student
