Aim/Timeline

Condense complex geo-info into multilevel vibrations and let the user experience navigationrelated info through tactile feedback

Non-obtrusive design setting. The system should be such that it fits the daily life of the user,avoiding him to worry about multiple devices and their handling.

Keep the design simple and used components cheap. Keep the design open-sourced Write a DIY guide through a editable Wikipedia where users can participate----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Build 4-5 robust prototypes with custom PCBs and test with users. -8 weeks Re-iterate design -4 weeks

Why

Presently people with limited vision and blinds depend solely on

Walking canes- Only helps detect obstructions

Friends/Other people who would always hold their hand and assist

Other voice based navigation aids can be distracting: blinds use their ears the most!

Expensive complicated stuff doesnt work! Nobody wants a 200$ camera over theirhead and a mobile phone in hand!

The Le Chal / Take-Me-There approach

How

- User speaks the final destination before starting his journey through an Android Appor his Desktop, which are in Sync.

- The maps data from Google maps is fetched and turn by turn directions to thedestination is loaded within the shoe

-The user starts his journey, which changes his GPS coordinates and headingdirection(calculated by compass within the GPS module)

- A vibration feedback indicating his direction of turn is activated within the shoe- The length of vibration depends upon the overall proximity from the destination i.e.

weak vibrations in the beginning and incrementally longer at the end of the navigation

task

Assemble it yourself!

- 8 mini vibrational motors= INR 90- A sole of the defined dimensions = J- An Arduino Lilypad GSM+GPS shield = Custom made in India for 400 INR- A wired version would cost around 150 INR including all components

Currently Working on

- Finding appropriate labs/fab-units where rapid prototyping and iterations could be done.

- Fabrication of a simple PCB for MEMS circuits

- A visualization tool for the commuted path. Open Source.- Exploring ideas how multiple user scenario could decrease the commutation time
