De meningen ge-uit door medewerkers en studenten van de TU Delft en de commentaren die zijn gegeven reflecteren niet perse de mening(en) van de TU Delft. De TU Delft is dan ook niet verantwoordelijk voor de inhoud van hetgeen op de TU Delft weblogs zichtbaar is. Wel vindt de TU Delft het belangrijk - en ook waarde toevoegend - dat medewerkers en studenten op deze, door de TU Delft gefaciliteerde, omgeving hun mening kunnen geven.

Sensors update week 5

We started off in week 5 with the ‘Mind Flex’. We measured the voltage across the 5 LED’s. The heigher the voltage, the more LED’s light up. This voltage can thus be linked to your brain activity. Low voltage means low activity. The excact values do seem to differ from person to person. We may adjust the pre-installed values on the ‘Mind Flex’  if it turns out this gives better results for our project. We will test this on different users.

Sensors update week 4

In week 4, we tried to connect and read the heart rate sensor with an arduino. We also started with the manipulation of a ‘ mind flex’  game in order to read brain activity.

Monday morning; with new deployment and good cheer we started today to make some progress.
But…Arduino decided not to work and caused some problems so that the heart rate monitor is not able to work. Everything is slowed down because the computers are not that fast.

Becide Arduino that does not work, the fluids has not arrived yet so we can not work on this side either. We hope that the fluid will arrive today but we do not know for sure. Hopefully we will make some progress today.


Heart rate monitor

To add another variable to determain the users’ emotion, we want to measure the users’  heart rate. We will do this by using the ‘ Polar heart rate system’ . This includes a normal chest strap used in fitness. To read the pulses use a ‘ polar heart reate receiver’ . Continue reading

Programming; 1 sensor, 3 outputs

Starting the programming phase of this project, we began by making 3 LED’s wich respond to a temperature sensor.

By squeezing the sensor between our fingers the measured temperature will rise. When the temperature is ‘ low’  only the green LED lights up. When the themperature is ‘ medium’  also the orange LED lights up. When the temperature is ‘ high’  all three LED’s light up. YouTube Preview Image

Research week 1

We began this project by looking at existing products, at things we can measure and how to display various emotions.
