Thesis Statement: Self-sustaining inexpensive interactive surfaces can support wireless communication of speech, movement, and touch interactions with feedback in indoor scenarios.
Abstract:
Current computational augmentation of our environment requires a bulky power-intensive expensive add-on IoT device. To get rid of these add-ons, I build maintenance-free, inexpensive, easy-to-deploy interactive surfaces. I take three system design choices into account - power, form factor, and cost. The interactive surfaces have simple circuitry that can self-sustain themselves to wirelessly collect, interpret and respond to a wide variety of human interactions e.g., talking, touching, swiping.
This work will introduce three projects with iteratively increasing computational capability. First, SATURN is a self-powered paper microphone based on a triboelectric generator made from inexpensive everyday materials like paper and plastic. Next, leveraging extremely simple circuitry ZEUSSS I add wireless speech communication capability to a single SATURN microphone. Furthermore, this work demonstrates the simultaneous communication with multiple MARS by enabling nano-power multiple-channel wireless communication capabilities for direction, identity, speech, and touch sensing. Finally, this work proposes a method for adding output in the form of a self-sustained feedback display powered by the human body.
The material device, circuit, and system innovations in this thesis pave a way forward for a world where computation can be truly woven into everyday physical objects and surfaces.
