Graphic design
In order to develop an application with an attractive user interface we need professional graphic designers. An app without an easy and attractive interface cannot be successful.
This graphic design could be used in all operating systems: Android, IOS, Windows Phone, etc.

Mobile devices for developement: apps, tablets, etc.
We want to develop and test our app for all kind of devices. We need at least the most commonly accesible mobile devices. We must consider size of the screen, availabilty of accelerometer, gps, gyroscope, etc.
|
€ 1.300 | |
|
Audio equipment
3 active noise cancellation headsets (1 on-the ear and 2 in-the-ear) in order to get a perfect isolation during the developement of the sounds.

Webpage: rankings, users online and information
We need a professional website connected to our mobile app translated to many languages. Moreover, we will publish the world ranking of players with all their information and statistics and the players waiting for opponents online in real time.

Costs related to our crowdfunding campaign
We will face the following costs:
-- professional video
-- taxes of Goteo and bank transfers (http://goteo.org/faq/sponsor#q98)
-- promotional images
-- rewards for contributors
-- communication costs
|
€ 950 | |

Solution of problems and bugs during the development
During the development of mobile apps (especially those that use connectivity and devices such as GPS, accelerometer and gyroscope) many unexpected issues come out. Solving them take more time than the whole developement of the project itself.
|
€ 4.900 | |
|
Marketing plan to broadcast our app
We need native people that spread out this project in several countries. They must contact different organisations in their countries (organisations of people with disabilities, cultural associations, etc.) during and after our crowdfunding campaign.
|
€ 900 | |
|
Improvement of the webpage
We will make our website more sofisticated and secure. This requires extra budget.
|
€ 500 | |

Related games such squash or paddle
Once we finish our tennis app we want to create different games and open a way for a new generation of sports.

General information
'Invisible tennis' is an open-source app project for Android, IOS, Windows Phone and other operating systems in which users play tennis with a virtual ball and use their device as a racket. This new sport was designed for blind people, those with other disabilities and also non-disabled ones.
Players orientate themselves through sound and vibration coming from their device. Our aim is to create very accurate sounds so each player knows where the ball is, and what is his own and opponent's position on the court. We also want to analyse the movement of the racket (mobile device) in order to make the hit as accurate as possible.
You can set a 1-player game or 2-players game (face-to-face or through internet). The match will be broadcasted via internet and everybody will be able to watch it on their devices with the representation of the ball and players in real time. A world ranking of players will also be created.
If we have enough financial resources we will create new games such us squash, fronton or paddle.
Main features and goals of the crowdfunding campaign
The app will track the position of the players as well as the direction and speed of the ball. Matches can be watched on other devices in real time with the updated view of the players and the virtual ball positions.
The court can be real or vitual. A real court consists of two players competing face-to-face on the site with real distances. A virtual one consists of, for intance, a game between a player from New York against one from Berlin. The dimensions of the court can be customised in each game.
Different game levels and modes will be developed.
A world ranking of online players waiting for a new match will be shown in real time. That will be visible through our app and through our website.
WHAT WILL BE THE MOST DIFFICULT PART OF THE PROJECT?
Everything related to GPS, accelerometer and gyroscope.
Why this is important
In the beginning it was aimed to be designed mostly for people with visual disabilities. But as it turned out anyone can have fun and play this game anytime anywhere by using only their mobiles.
Goals of the crowdfunding campaign
As engineers we have designed the structure and specifications of this project. If we want a professional result in terms of engineering, usage and appearance we need your contribution.
Our aim is that millions of people will enjoy playing this game soon.
We have experience in the management of mobile applications, specially for Android.
