This week, we made finished the integrating all our hardware pieces together. We have encasings for the raspberry Pi which is holding our GPS, battery, fan, and our distance sensor. We have the encasing for our wristband, which we can feel vibrations through when the sensor detects something in it’s field of view. We also decided to pivot from having a speaker + microphone attached to the raspberry Pi. Instead we are using a wireless headset which is acting as both a microphone and a listening device for the instructions. We were able to integrate this headset with the Raspberry Pi, using a bluetooth connection. After we got the encasings for all the devices we attached the connection to the gopro mount, and it is now able to be put on our bicycle for wholistic testing.
In terms of testing, we did more testing with our speech to text and our text to speech because we decided to use another speech model that was better for our bluetooth headset. This model also seemed to have more accuracy than the previous API we were using. We also tested our distance sensor to make sure it was good for detecting the motion of cars and when the user is in motion with the sensor.
RISKS:
There is potential strength of the connection piece for the mount not being strong enough to hold our device, so we need to see how it is riding quickly different terrain. There is also the risks of bluetooth connection not being the best with devices moving and every device being in encased, which could lead to choppy connection at times, but we will see with testing.
NEXT WEEK DELIVERABLES:
Continuous testing for the device still needs to be done, testing with actual cars and different journeys. We also need to get varying user feedback on the practicality of the device. We will be working on final presentations and getting working demo videos out.
