Doorbell University project

Hello everyone!

We are a group of students that are doing a project regarding the doorbell system for people with hearing disabilities. We would gladly appreciate some of your help by answering the questions below:

1. How would you like a doorbell system to be tailored to your needs?

2. What other sounds systems to you wish to be adapted for deaf accessibility

3. How could we implement our new system in a way that would suit your need ((main idea)current idea is to have a lighting system that will change colours) or ((backup idea)a  vibrating wristband)  

Any other input or suggestions will be very appreciated.

Thank you all for your cooperation!
