Interaction DesignImplementationFuture work

Interaction Design

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

At 9:00, parents send child to bed

The doll starts monitoring

child’s behavior

Scenario

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

Scenario

Interaction Design

Some design background assumptionHugging 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 effectSecurity blanket: children might be

attracted to the doll too muchAnnoy child at the mid-night: false-alarm

of motion detection might annoy child at the mid-night

Implementation

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

Setting recording start time I

Setting recording start time II

Implementation

Recording and playing

Using accelerometer

Further Work

It’s hard to detect children’s current sleeping status

Need field study to confirm assumption
