The team (Fabian & Zhou Yang) is inspired by Morse code. It is a type of character encoding system used in telecommunication. It conveys information through two different signal duration called dots and dashes. Through the use of short and long duration of vibration produced from a vibrator which correspond to the dots and dashes of the Morse code, we hope to convey information to our users.
Basic understanding of Morse code.
Concept sketch
References
We took references for the code of the vibrator from various sites to aid in our prototyping.

Vibrator motor
We use the following vibrator motor for our prototyping process:
Problems
The following are the problems we faced during the prototyping phases:
Testing of vibrator motor
Final arduino circuit
User testing
We tested out the final prototype.
We managed to condition ourselves to remember the different vibration combinations for the different functions. However, it took sometime for us to remember them. At the beginning, it was confusing to differential between the long and short vibrations. However, after some practice we are fine.
Problems faced
The following are the challenges we faced while prototyping:
Project description:
The idea is inspired by the traditional game catching. The game will consists of two teams preferably equal number of people on both sides. Each side will be wearing slippers with LED lights of different colors to differentiate from the other team. (Red and Blue) The objective of the game is to turn the LED lights of the opposite team into the other color. (Red to blue or vice versa.) They can do it by attempting to position their LED light in front of the light sensors placed at the back of the slippers players are all wearing. The game ends when one side of the team had all their members’ LED light changed color.
Areas of changes/improvements in concept:
Since the start of the development process we had make the following changes /improvements to the prototype:
Process:
Testing out the blue and red LED lights.
Fixing the LED lights onto the slippers for testing.
Assembling the arduino set up on the slippers.
Major issues:
We faced the following problems while prototyping:
1. The LED lights were unstable. They were showing random colors and blinking in random manners.
2. The LED lights were not responsive when we interacted with it.
These are some of the issues we faced while building our prototype. After troubleshooting, we realized most of the problems were solved after we change some of the parts as they are aging and thus malfunctioning.
3. Due to time constraints and our lack of knowledge and practice in Arduino we could not get the light sensors to work. In the end, we created a button function for the set up to mimic the triggering of the LED lights when the light sensor is activated.

Our code:
Project testing:
From the video, the LED lights are changing colors through the press of buttons to mimic the triggering of light sensors which will result in color change. However, we are having difficulty to make the LED lights response in a consistent manner.
