For a dumb it is difficult to express his ideas through his words, for a blind it is impossible to see and recognize the buttons in panel. With help technology disable can interact with public facility used daily quite easily.The basic the idea is to connect disable's people’s smartphone with various common facilities like elevator, train, buses, departmental stores, ATM machines etc in one tap and therefore transfer all the required data for operation.Let it be any kind of disability smartphone is accessible using voice recognition,image processing ,android talkback features.This brought me up with an idea of e-DoorMat.I am still working on prototype of this idea therefore i would like hear some suggestion.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Channel
- Intel Edison
- NFC transceiver module-like ST95HF
- Rechargeable battery source-4.5V
Working:Channel is the connecting pathway between the e-doormat and the user’s smartphone. For that I have placed NFC transceiver in one of the boot of disabled or in case of crippled in their wheel chair base.NFC module ST95HF will connect to the Intel Edison board through SPI port and will perform NFC based Bluetooth/WiFi pairing action or peer to peer connection.The Edison board will transmit information to the smartphone via inbuilt Bluetooth.
Step 2: E-DoorMat
It is basically a strip of multiple NFC chips aligned in a desired order.These will be placed in on the entrance of service which the user will be using like inside taxi, elevators ,next to metro entrance.They are divided in two categories on the basis of use:
- Passive Mat
- Active Mat
Passive Mat:It consist of multiple NFC tags aligned in straight line mostly 8- 10 tags/meter.These tags will initiate NFC based pairing.These will be placed on the entrance of the elevators, taxi or in restaurant entrance.While using this mat we have install a Wireless module as input in the system.
Active Mat:These mat will consist of a NFC transceiver of its own which will be connected to the public facility as input.This mat can be placed on floor of ATM machines,or metro entrance etc.These may be used for NFC payment exactly as it is done using phone.
A mobile application will take input from the user in advance and execute them in time of need.Application could understand the daily habits of user, can interact with things around and can further work more efficiently.
