Describe what your project does and how it works
So our project is basically a semi-glove made to play without needing a keyboard. It have pressure sensors in the tip of each finger; When the user press the finger against a surface, the difference of pressure sends a signal to the Arduino board and it computes the signal and recognizes send it via Bluetooth to the computer. The application running in the computer receives the signal and simulates a keystroke pretending that the user is pressing that key on keyboard.
What are your overall feelings on your project? Are you pleased, disappointed, etc.?
Satisfied. After a lot of hard work and problems with pressure sensors (we tried velostat at first and it didn’t worked well) and coding (we discovered that a keystroke isn’t the same than sending the corresponding key to the console) it worked like we expected and meet with what we expected to do in the end.
How well did your project meet your original project description and goals?
Pretty well. We wanted to make the use of a keyboard to play games dispensable and in fact we did this. Our only limitation was the amount of keys that can be pressed with only five alternatives, which limits how many games can be played using the gaming gloves. But we already thought about how to fix this limitation in a future prototype: using a shift key in one of the fingers to double the alternatives of the remaining fingers. And if 8 keys isn’t enough, the user can make combo movements with fingers to create more commands.
What were the largest hurdles you encountered? How did you overcome these challenges?
The keystroke issue and the velostat. About the velostat: we just figured out that velostat was not the best option to do what we wanted because of it was not sending a reliable signal when pressed so we just changed to pressure sensors and fixed this problem. About the keystroke issue: After finishing the code (at least we tought it was finished) we figured out that the glove was working on notepad(it was writing Q,W,E and R when we pressed the corresponding finger) but ingame the skills Q,W,E,R were not working. So after a research we discovered that what we actually need was the software that receives the signal to simulates a virtual keyboard instead of just writing Q,W,E and R. After almost a hole night studying about the code and searching in the internet, we found a library that helped us to do what we need to fiz the problem.
If you had more time, what would you do next?
A mouse glove to completely remove the need of having a mouse or a keyboard to play computer games at the comfort of your couch.
This week we finished the finger’s cover with the pressure sensors added to it. As you can see in the picture below, we made a two layer’s cover to hide the sensors. We had already tested and all of the sensors are working perfectly by sending a response whenever it suffer any pressure. The arduino code is already done and we plan to finish the software by Wednesday. Besides the software all we have to do is just finish to plug all components of the glove in the actual prototype what should take us less than a day.
Things finally start to work for our side this week. We finally received the Bluetooth module. We had to buy another one because we didn’t receive the first order. Our fabric was also delivered this week so we could start to saw the tip of the fingers for the gloves. Because of all this problems with deliveries the project is late on the schedule, but since the software is something pretty simple to develop it will be easy to get things under schedule again.
Below are some pictures of our work this week.
Until next week!
The tip of the fingers made with a really thin neoprene.
The Bluetooth module.
This was a hard week for our project because of two things, our Bluetooth module was not delivered and we decided that we would use force sensitive resistors instead of Velostat. The good part is, the force sensitive resistors were already delivered and we already know how to use them after a few test.
So I hope that in the end of this week we will already have a prototype of our project!
Here are two pictures that I took from my tests with the resistors:
Some of the results from the test:
Project Title: Gaming Gloves
Project Members: Vinicius Furlan, Jhonatt Lima
Description of what you are going to do – We want to build gloves that will be used to replace keyboards necessary to play games. Our idea is to facilitate the game play when you are not in a good environment to play certain games.
Description of Materials you plan to use along with the costs for these materials :
Arduino Nano board: $8
Velostat pressure fabric: $4
Bluetooth module: $6
11/11 – Circuit finished and start of the software
11/26 – End of the software and beginning of the tests.
This is a project that I’ve been thinking for a while, and its kind of expensive but can be really useful in cold days. It is a multimedia jacket to basically control your smartphone through Bluetooth and Arduino.
This coat would have headphones, a microphone, an accelerometer, a gyroscope, and a LCD that would be used to pass some basic information to the user. In addition to those features you could use discrete solar panels on the shoulders to recharge the batteries of your Arduino and even track some basic accidents measuring pressure in key regions of your jacket.
The challenges that people might face in this project would be:
– Solar panels are expensive.
– How to determine that the user is in danger.
– How to efficiently use the solar panels to recharge the batteries.
The MBody project was created to help athletes to track important information about their body during their workout. It consist of a shorts that have sensors to monitor the leg muscles and a live application who receives the information sent by the short to show real time information about muscles load, heart rate and balance.
Why I selected it
I chose this project because it is a practical example of how wearable technology can help people to live a better life. This project uses sensor to inform people about an important data that we couldn’t track before.
How well you think the project accomplishes its objectives
I think the MBody it’s pretty effective and useful in its purpose, because the information provided by it can be used to prevent injuries caused by excessive effort. Another good point of the project is the MBody coach app that provide real time advice to the athlete.
