SpeakCup: Simplicity, BABL , and Shape Change Jamie Zigelbaum, Angela Chang, James Gouldstone, Joshua Jen Monzen, and Hiroshi Ishii

ABSTRACT a simple tangible interface that uses shape change to convey meaning in its interaction design. we explore the coupling of shape and action in an interface designed for simplicity while discussing some questions that we have encountered along the way.

a simple tangible interface that uses shape change to convey meaning in its interaction design.

we explore the coupling of shape and action in an interface designed for simplicity while discussing some questions that we have encountered along the way.

As an experiment in simplicity we created SpeakCup, a digital voice recorder in the form of a soft silicone disk that relies on shape change as input. We are interested in shape change as a way to privilege simplicity in interaction design and also as a means to incorporate physical metaphor or analogy into new devices. INTRODUCTION

As an experiment in simplicity we created SpeakCup, a digital voice recorder in the form of a soft silicone disk that relies on shape change as input.

We are interested in shape change as a way to privilege simplicity in interaction design and also as a means to incorporate physical metaphor or analogy into new devices.

We first imagined SpeakCup during a design exercise in which we challenged ourselves to create interfaces with minimal feature sets without relying on abstract buttons or blinking lights . SPEAKCUP

We first imagined SpeakCup during a design exercise in which we challenged ourselves to create interfaces with minimal feature sets without relying on abstract buttons or blinking lights .

SpeakCup’s body is made from a six-inch disk of platinum cure silicone rubber. A ring of aluminum is embedded inside the outer rim of the disk so that it stays round when deformed. A combination microphone/speaker is embedded in the center of the disk. Red and green LEDs are wired around the perimeter of the microphone/speaker. Two flex sensors that change resistance when bent span the diameter of the disk embedded in the silicone and facing in opposite directions to sense deformations on either side. SpeakCup is wired to a protoboard where the electronics and batteries that power it are located. We used a cheap RadioShack voice recorder module with 20 seconds of memory to store and playback sound. We rewired this module’s buttons, running them through analog electronics to connect the flex sensors and drive the LEDs. Implementation

We rely on metaphor to inform the use of SpeakCup. The disk has seven holes on one side, deforming SpeakCup so that these holes become the bottom of a cup triggers the sound recording. Although during the design exercise we initially conceived of SpeakCup without LED feedback we added this feature during implementation because it provided clear feedback for the user.

We rely on metaphor to inform the use of SpeakCup.

The disk has seven holes on one side, deforming SpeakCup so that these holes become the bottom of a cup triggers the sound recording.

Although during the design exercise we initially conceived of SpeakCup without LED feedback we added this feature during implementation because it provided clear feedback for the user.

Although our goal for this work was simplicity of function and form we experimented with adding more expressive power. This method was interesting but it added an extra level of complexity that we were unable to integrate into the existing metaphor so we did not develop it enough for testing. The simple version of SpeakCup turned out to be best. Although limited in functionality, we have found some promising uses for it, for example as a toy for social interaction in public spaces—users drawn to SpeakCup’s novel form could record messages and stick them to a wall for someone else to experience.

From our informal testing we found that users enjoyed SpeakCup. At the same time we are skeptical about using these techniques for feature rich applications. CONCLUSION
