Harnessing Technology project
a group project about haptics
One aspect of haptic interactivity is the direct relationship
between the way a user touches a device, the immediate response
of the device, and the user's interpretation of that response.
To explore the qualities of such interactivity, four plain
boxes were designed and programmed to produce natural, meaningful
responses to input from a user's hand. A user interacts with
each box by approaching and touching it. When each box is
touched, it reacts in a unique way. The reaction to the user's
action establishes a relationship between the box and user.
During this project the all group was involved in compiling
a short research about the state of the art in haptic technologies.
We had also the opportunity to visit the PERCRO lab of the
Scuola di S.Anna in Pisa.
See the group website
for a comprehensive documentation.
My Tofu box: Pandora
developed with Livia Sunesson
Pandoras box is connoted with her own behaviour.
The walls of the box are halfway open until you approach them
with the lid.
When you try put on the lid on the box, the walls will stand
up straight to support the lid. The box will help you to close
itself up. The box will complain if you don't put on the lid,
through movements of the walls.
Reminding the myth of the Vase of Pandora, the box should
try to prevent you to keep it open.
Input: IR emitter placed on the lid of the box. The IR receiver is inside the box.
Output: servo motor with a wheel. The wheel is connected to the walls through few threads, rotating at the variation of IR it moves the walls.
