Physical object memory & its relation to user interfaced design. Points and images taken from Kate Devlin's UID Lecture slides. Related slides found here
Sensor-based interaction where physical ojects i.e. bricks are coupled with digital representations
When a person manipulates the physical object/objects it causes a digital effect to occur i.e. an animation. Digital effects can take place in a number of media and places or embedded in objects.
A physical exploratory system embedded in objects.
Examples
Chromarium cubes
– when turned over digital animations of color are mixed on an adjacent wall
– faciliates creativity and collaborative exploration
Flow Blocks
– depict changing numbers and lights embedded in the blocks
– vary depending on how they are connected together
Urp
– physical models of buildings moved around on tabletop
– used in combination with tokens for wind and shadows -> digital shadows surrounding them to change over time
Benefits-can be held in both hands and combined and manipulated. Multi person exploration possible & encourages alternative ways of exploring and representing a problem space. People see and understand situations differently-can lead to greater insight, learning and problem-solving than with different kinds of interfaces. Creativity and reflection.
Design issues-how to map between action and effect. What physical aspect to use.
