David states that he drew on the idea of playing with building blocks
as a kid, tactically feeling everything and learning from our interactions
from the blocks, what if when we use a computer, its the same basic
Instead of a mouse cursor serving as a single fingertip around the
desktop, reach ion with both hands, physically grab the information
stored there, and arrange it however we like.
Each siftable is the size of a poker chip. Each is also an integrated
computer system with native data. Pick them up, move them around by
hand, and slide them together. They detect when they are next to another
siftable, and the two are capable of exchanging data.
David demonstrates one individual siftable that's displaying a video.
An internal gyroscope and accelerometer means he can change the rate
the video plays by tilting it in different directions.
Combining the awareness of nearby siftables, relative positions and
this tilt mechanism, he has gone one stage further, by allowing users
to 'pour' information from one siftable to another, by literally holding
both and tilting one over another, simulating the pouring motion.
Siftables configured to display numbers and maths signs can be dynamically
rearranged likewise, into scrabble-like strings, where they will automatically
compute the sums they are placed into.
