What are the most significant risks that could jeopardize the success of the project? How are these risks being managed? What contingency plans are ready?
We are concerned about our planned method of mapping the detected coordinate in an image to the gui. We are not sure if in practice our design will be accurate. Our plan is to detect the coordinates of a green border along the perimeter of our gui. We will use these coordinates to find the relative distance of the button coordinates to the border. In the case that these detected coordinates are not precise enough for this application, we will place four distinctly colored stickers at the edges of the gui and will use these as reference.
We are also concerned about using the raspberry pi and Python for the piezo sensor circuit. We are prototyping with an Arduino for now and if we are unable to use the raspberry pi, we will continue to use the Arduino and send data to our Python color_detection.py script through a serial port. In this case, we will have to deal with any possible delays in sending a message to the python script.
We also need to spend a significant amount of time taking more test images to train our SVM. Currently, we have 26 test images with our poster board setup. We will work on taking more test images this upcoming week.
Were any changes made to the existing design of the system (requirements, block diagram, system spec, etc)? Why was this change necessary, what costs does the change incur, and how will these costs be mitigated going forward?
No new design changes were made this week.
