Multitouch Table at MoMA

MoMA Installation

Overview

An interactive multitouch table developed in cooperation with the Museum of Modern Art (MoMA) New York for the "Un-Private House" exhibition in 1999.

For this interactive multitouch table, I developed a sophisticated sensing array installed beneath the table surface. This array could precisely locate the x and y positions of users' hands both on and above the table surface.

The system works by measuring the rate at which electrical charge accumulates on each electrode in the array. When a hand approaches the table, it affects the local electric field, requiring more charge and thus slowing down this rate. A predictive model was developed to calculate the expected charge variations based on hand position, allowing the system to recognize when a hand enters designated "hotspot" areas.
