The Easy Communicator (ECO) application is an implementation of an Augmentative and Alternative Communication (AAC) system for mobile devices. Its aim is to provide a tool for improving the possibilities of communication and understanding, both in personal and academic environment, of people with language, learning or interaction difficulties. The groups to which it is addressed are: from children with disorders of autistic spectrum, to teenagers with cerebral palsy, or seniors with cognitive problems.

ECO combine several communication elements: photos, pictograms, videos, texts and voices. Thus, messages are offered with complementary alternative formats. For example, the concept "school" can be either a customized photography of the user’s school, the generic pictogram, the video of the word school in sign language, the word read and the text, etc. There are several collections of pictograms, voices and videos available. Some of them are for free, such as ARASAAC, whilst other are commercial or proprietary. ECO allows both, incorporating these sources and structuring them internally, or using a small set of own development.

ECO provides facilities to:
- Organize the messages according to users and categories
- Create, edit and sort users and categories
- Import and export users and categories.
- Associate image, video and audio files with messages
- Customize the interface, by modifying font sizes, colors, response times, sorting patterns, response patterns, etc.

ECO comes with several users already installed, which are aimed to illustrate the performance of the application in terms of:

- Show emotions and responses to help users to hold conversations.
- Schedule and remind daily actions in a personal agenda
- Learn simple concepts through lessons (colors, numbers, flowers, etc.)

Application optimized for devices with 7" (or larger) display, with a minimum resolution of 600 x 1024 pixels.
