
Outline
Purpose = try to help parents build their
children’s good sleeping habit
 Target preschool children

Interaction Design
Child doesn’t
go to sleep at
8:50
At 8:50, the
doll calls
parents and
child to play
The doll
records the
playing scene
for 10 mins
The doll starts
monitoring
child’s behavior
At 9:00,
parents send
child to bed
Interaction Design
If child is
sleeping, the doll
keeps playing
recorded scene
If child is moving,
the doll stops
playing to alert
the child
After child really
falls asleep, the
doll stops playing
Interaction Design
Some design background assumption
 Hugging a doll is like staying in mother's
comforting womb.
 Recording and playing parent-child
interaction sound attracts child staying in
bed and isn’t too stimulus
 Making the sound boring usually makes
people fall asleep

Interaction Design
Some negative effect
 Security blanket: children might be
attracted to the doll too much
 Annoy child at the mid-night: false-alarm
of motion detection might annoy child at
the mid-night

Interaction Design
Using a Dopod smart phone as recording
and playing platform (Implemented)
 Using WiTilt accelerometer to detect
children’s motion on their bed (Can
connect but not work now)
 Integrating with a doll (Not implemented)

Implementation
Using
accelerometer
It’s hard to detect children’s current
sleeping status
 Need field study to confirm assumption
