Outcome

Description

Sibling Love connects two siblings that are geographically separated. The doll can be placed on a desk leaning against the wall. When one user "pokes" the belly of the doll, the other doll will bite. Similarly, when one user pulls the hair of the doll, the other one will kick. In this way, two siblings can continuously show their love through annoying physical actions even if they are not together. 

Process

The first step was to come up with as many annoying actions that siblings do to each other as we could think of. The final list was: biting, kicking, poking, and pulling hair. Afterwards, we developed a storyboard to display the actions we wanted our device to perform. 

Storyboard

Next we made an initial prototype to test the concept and code. At the same time, we split up the code to work on the poke and bite scenario on one particle, and the hair pull and kicking scenario on another particle. 

Finally, after testing, we developed our final prototype and code.

Future

In the future, we would like to better manufacture the doll so that it looks more realistic. Secondly, we would like to add more interactions that siblings could do with the doll including adding sound.
