The idea is to have a wrist mounted sensor to give an indication of sensory "load", with an aim to help Autistic people show or be aware of increased sensory situations. This is detecting the SCR (Skin conductive response) to try to get an idea of the level of activity, while this isn't an absolute measurement of what we want it appears to be a good indicator.
This information can then be processed and displayed in way of an RGB led for information of the individual or others.
The aim here is to build a device to log the EDA, then add a way for it to process the information and display it. As I am yet to find a device that can do this at mid cost.
I have been working on this for a while and been making small progress. I have several days or recordings but currently no real way of analysing it with the goal of processing it in real-time. This is an area I am not good at hence this project to see if the wider community could help.
I have drawings, data and links to post to this project that should be helpful. I also have gaps in what I have documented and could do with a prod if something need to be included.
This article provides a good explanation of what the signal looks like https://imotions.com/blog/skin-conductance-response/ for this we are ignoring the tonic and counting the phasic response aiming for a count per min/5min and basing the indicators off of that.
