The Soap Bubble Interface

January 26th, 2010

The Soap Bubble Interface is an ephemeral user interface that uses liquids, smoke and soap bubbles for computer input. Users can generate normal as well as smoke-filled bubbles which drop onto a dark liquid surface. As the bubbles are tracked by a camera from below, the position of the floating soap bubbles can be used to control digital output like graphics, ambient light, or sound. The fragile soap bubbles can be moved either by blowing or touching them cautiously and thus create a special interaction quality which includes that they elude the complete control of users, as the bubbles inevitably burst after a short while. Thus, the soap bubble interface provokes thoughts about durability, control, and materiality of tangible user interfaces.

Demo Presentation at TEI’10

January 25th, 2010

We presented the Soap Bubble Interface at the fourth international Conference on Tangible, Embedded and Embodied Interaction (TEI’10) hosted at the MIT Media Lab in Cambridge, USA , January 24th to 27th. It was mentioned in an article about the conference in the Technology Review Blog (You can also find a short video there). Tanja also gave an Video-Interview to Kerime B. Toksü which you can watch on her 2literal.com blog.

Liquids, Smoke, and Soap Bubbles – Reflections on Materials for Ephemeral User Interfaces

January 24th, 2010

Paper Abstract

In this paper we inquire material qualities for tangible user interfaces and introduce the term “ephemeral user interface”. We present an example user interface that employs fragile soap bubbles for human-computer interaction: the user has to move or blow bubbles over a dark liquid surface in order to interact with a computer system. Our installation uses liquid, smoke, and soap bubbles as unusual and transient materials, which demand a very cautious and calm handling, and furthermore elude the complete control of users, as the bubbles inevitably burst after a short while. Thus, the soap bubble interface provokes thoughts about durability, control, and materiality of tangible user interfaces.
