Since the previous presentation we have done, we have been questioned is the driver has to be naked because getting ECG signal usually it is by skin contact with electrodes.
We have spent a long time to search how to get ECG signal without skin contact. Although we found it but we don't understand how it works even after reading, due to this is the knowledge we never touch before. We also found what kind of sensor can get ECG signal through clothing without skin contact.
We wish to explain and prove how ECG can analyse drowsy signal, but it seemed like we need more research to do.

Week 7 - Technology Project APPT 6212
11/04/14 (Fri)
Last night we did research and we discussed our project until late night at my place. Due to we both have to work as part time therefore our process were slow.
Today was our stage 1 demonstration for our project. We have shown the basic system flow chart as below:
1. Signal from sensors
2. Signal conditioning (filter & amplifier)
3. Beat to beat interval detection
4. HRV library (general information)
5. Drowsiness detection
6. If driver is drowsy, warning will be given
7. If driver is no drowsy, system will keep monitor
From the presentation we have explained that we are now only focus on doing drowsiness detection in our project. Due to the alcohol issue it is needed another components to check the alcohol containing from human skin.
We planed to locate the ECG sensors on car seat to get ECG signal from driver's back, and also another sensor on the seat.
The material of sensor we will use which is conductive fabric. It is because of low cost and it can sense tiny electric signal of your muscles.
The reaction of the system, we decided to put warning sound until it switched off by driver. Moreover, the vehicle speed will be slowed down or stopped if warning system did not turn off.

Week 6 - Technology Project APPT 6212

We are still confusing about how to find the information that which can support on out project, and where is the direction to do our research. We do believe that ECG can determine on drowsiness but we can't even find one of the evidence to prove it and also can't get the electrocardiogram of drowsiness, most of them are heart attack or heart disease. So we still not clear on this area.
In the other hand, we are starting to discuss the whole system operation, the warning action, the components of the system and material. We also discuss what kind of information we need to prepare for our next presentation. We still have many unclear information are waiting to be solved.
