Just ordered some new parts to work on a wearable prototype to read and collect bio-metric data. These parts don't quite fit the form factor that I'm aiming for but they make it much easier to work towards a more optimal design.
I choose the Adafruit Feather M0 Bluefruit BLE as my microcontroller because it has a number of elements included that simplify prototyping:
- Arduino compatible microcontroller (lots of community support)
- Integrated USB communication (easier debugging)
- On board connection for LiPo power (including voltage regulator and charging)
- On board Bluetooth BLE
- Only interested in pulse data (to determine heart rate) - don't need the oxygen saturation data.
- The Pulse Sensor Amped can directly output IBI (inter beat interval) data directly from a microcontroller (using open source software).
It is likely possible to get this data from the Maxim breakout but the learning curve is to steep for me now. Another plus is that the Pulse Sensor Amped uses green LED's which are likely to make data collection from the wrist easier.
Just a quick update and now I'm getting back to working on this.

This project is an outgrowth of my Voight-Kampff project. My goal is to use what I've learned (as well as what I'm continuing to learn) about physiological markers for emotion and focus this on better methods of facilitating communication for people who have difficulty expressing emotions though facial expressions, vocal intonation or body movements.
Currently there are a number of applications for detecting emotions through analysis of facial expressions (Microsoft's Emotion API, Empatica's facial analysis, etc). These do a truly amazing job at detecting emotional expression and their abilities are growing daily but they only work with those who have no impediments in expressing emotions.
The above technologies offer great promise in helping people learn to recognize the non-verbal signals of emotion (facilitate recognition of emotional states in others). This is an application that is being pursued, especially to help people who fall in the autism spectrum.
For those who do have difficulty (due to various issues) in outwardly expressing emotion, there does not seem to be similar efforts (at least that I've found so far - please let me know if I'm incorrect!). The primary goal of viEwMotion is to address that very issue.
There are numerous other potential applications for viEwMotion ranging from research into emotional response (especially by Citizen Scientists), game design and play (increased immersion due to game response to player emotions) and even market research (analyzing emotional response to advertisements, etc.).
