eMo (myoelectric – myomechanical sensor array)
This fantasy device or concept prototype describes a device that might be able sense muscle tone and muscle movement in the larynx both while a user is speaking and silent. The device employs a combination of myoelectric sensors (the muscle’s electrical pulse as transmitted by the motor cortex) and myomechanical sensors (the physical pulses that muscles produce). Together with speech processing an other biometric sensors like pulse and GSR the device would hope to detect a user’s emotion state in realtime and be able to use those emotional cues to enrich human computer interaction.
The myoelectric sensors consist of 3 electrodes (2 redundant electrodes supplying current and one grounded sensor that reads the muscle’s nerve activity). The myomechanical sensors are simple microphones with silicone dampening and low pass filters (muscular pulse frequency ranges between 20 – 30Hz).
Though this initial prototype is somewhat cumbersome, subsequent designs could most likely be scaled down.
Some of the papers that I used as reference on this project include:

This is a very high fidelity fantasy device – excellent work. I love the background research!
I can’t get over how you actually MADE all that. It looks really professional. And it kind of looks like something from a horror movie. Professional mad scientist?
