IRiS is an ever expanding range of products that can stimulate, calm a person or aid in the development of their lifeskills regardless of age or ability.

This application allows the user to control any number of IRiS Listeners with the following inputs: - Touching coloured buttons on the device screen - Placing the device inside the coloured Qube so that the colour on the top of the Qube is selected - Using the microphone in the device (if it has one) to respond to sound - Using the movement sensors in the device to respond to vibration - Using the compass sensors (if they are present in the device) to respond to user orientation - Using the touch screen or tilting the device to control the movement of an IRiS scanner - Using RGB sliders or colour wheel to control RGB capable lights - Using speech recognition to change light colour - A calming mode that slowly cycles through colours with no input required The application will work even if not connected to an IRiS+ module – so you can download the app and see what it is capable of. We are sure you will be impressed by its potential to help people with special needs!

Fun English alphabet and number tracing game for preschool & kindergarten kids! Learn how to write with correct formation. Are you having trouble teaching your preschooler and kindergarten children how to write letters and numbers with proper formation? The UptoSix Letter Formation App is perfect for your child. This app is fun, engaging, and developed by experienced teachers to teach your children how to write. Kids can watch and learn how to write correctly. Unlike other apps, this does not auto-correct a child’s writing. Children really learn to Write ABCs and 123s. Preschool and Kindergarten children must learn to write letters and numbers with correct formation. Once they have learned how to construct letters or numbers correctly, they need to know about the sizing and placement of the letters so that the handwriting looks neat and legible. It is a gradual process, and children need guidance for this. Otherwise, children are likely to pick the wrong way of writing, which is very difficult to correct later. LETTERS AND NUMBERS An animation repeatedly plays to show the proper letter and number formation. Children watch the animation and try tracing independently on the big red letter. A stylus or a finger can be used to trace. Tracing with a finger is similar to writing on a sand tray with a finger or on a slate with water. Writing with a stylus is similar to writing with a pencil on paper. So kids start with finger tracing and gradually progress to paper-pencil writing. HOW THE APP IS DIFFERENT FROM OTHER APP The app does not auto-correct the writing. This app does not give any false sense of achievement to the children. Accurate finger control happens, and children learn to write in a fun and engaging way. FOUR LINES WRITING Once children have perfected letter formation, they must learn about letter sizing and spacing and keep their writing within the designated space of the page. Kindergarten children learn to use the four lines on the page to guide the sizing of the letters. Chicken, giraffe, and monkey letters are useful for remembering which lines to put the letters on. CHICKEN LETTERS are small. They sit between the two middle blue lines. Like ‘a’, ‘c’, ‘s’. GIRAFFE LETTERS are tall. They have long necks; they touch the top red line. Like ‘b’. ‘d’, ‘h’. MONKEY LEYYERS have a tail that falls and touches the blue bottom line. Like ‘g’, ‘y’. Capital letters and numbers are all giraffe letters. PRE-WRITING SKILLS FOR FINE MOTOR SKILLS Children who need help with more finger control exercises can practice Pre-writing skills. By tracing different types of lines, they can master various finger movements. FEATURES - A colourful early education game that helps children learn to write -Uppercase and Lowercase Letters of the alphabet - Numbers - Chicken, Giraffe and Monkey letters -Four lines writing - Pre-writing skills -Smart interface helps kids focus on learning without accidentally exiting the game. We hope this app will help Kindergarteners and preschoolers to learn to write with PROPER FORMATION in a fun and engaging way. LEARN TO READ WITH PHONICS.
