The goal of this project is to build an application based on a mobile platform like Android in order to test the viability of the patented technology TouchOver (r) to provide a haptic interface to aid visually impaired people to use their mobile devices in a more natural way. We need a highly skillful app programmer in Android but iOS knowledge will be desirable. An knowledge of PWM (pulse width modulation) and DSP techniques and real time interrupt controllers implementation over Android is a must as it is required to control vibration motor in a PWM fashion in real time depending on user movements and multitouch through screen and activities. Image processing, OCR and filtering basics knowledge should be also valuable. The project is totally innovative and should be interesting and challenging for any applicant as the result will help visually impaired people using their mobiles and tablets as well as create future teaching apps for them also allowing our elders to integrate better in the digital world. The job is very much described in a pdf document in English with examples, images and options, that will be delivered to you when pre-selected and NDA signed. We already have a simple demo working application built in TouchDevelop for you to understand the main concepts applied in this app. You'll have to take into account that some of the options defined will be activated in a in-app purchase option and some free options with advertisement should also be activated if needed. Both behaviors should be defined during the development. The job is divided into three main tasks (Documentation and a test app should be implemented as well as source code commented must be delivered for every milestone): 1. Vibration Core Design You should design a real time interruption controller in order to generate a continuous vibration control signal composed of the summation of up to 10 simultaneous real time vibration patterns. This signals are generated depending on the location and the way user touch and swipe his/her fingers on the current screen elements (buttons, icons, sliders, text, graphics, etc). 2. User Interface In this task you will integrate some user gestures to actions like activate/deactivate functions and application with gestures on screen like double two fingers tapping, circle to right or left, etc. Gestures are defined in the description pdf document. You also will generate a Braille level 1 alphabet. Braille alphabet is explained in the pdf document with some examples and it is already designed for Spanish language. You should design it in English as it is straightforward and will design an easy way of updating the alphabet database for future languages depending on the user defined language. Finally a Text to Braille conversion should be implemented and showed a Braille text line in an area on the screen when user touch a text on it. A simple color conversion RGB to text will also be implemented. Example on how can it be implemented is explained in the pdf document with examples. Also an easy way to update colors and languages must be implemented for future updates of the app. Text to voice when selected is a straightforward function to be implemented too. 3. Setup activity should also be implemented finally in order to allow setting up the application as a function of user requirements. An optional graphical integrated tool could also be developed in order for the user to assign patterns and actions to areas in images or screen so impaired people can get voice, vibrational information or both when touching the user defined areas in screen or image. This is also described in the pdf document. Finally internal experiments with real blind people will be done and the feedback should be used to modify or add some features to the application in the final version. Please add the word "haptic interface" to your application.
