Introduction

In this project an API for wheelchair has been implemented. The target of the API is to get different information of the wheelchair. The information is given and recieved in json format.

Motivation

The project is made for the my Academic thesis - "Secured wheelchair in IoT Environment"

Features

• Fall detection using Accelerometer data (Used threshold technique)
• Control Wheelchair

Quick start running the project

1. git clone https://github.com/asif001/wheelchair-api.git
2. Create python virtual environment with python-3.7.3
3. Install required python dependencies into your python virtual environment using pip install -r requirements.txt
4. Comment out cloud config section and uncomment local config section in app.py to run locally
5. python app.py db upgrade
6. python app.py runserver
7. Go to http://127.0.0.1:5000/<params> to get data for given params. The list of params are given below

Params

• All data are sent and received in json format

1. status -- To send and receive whhelchair status

• POST: {"Accelerometer": accelerometer_data}
• GET: {"Accelerometer": .. , "FallStatus": ..}

2. direction -- Control wheelchair in different direction

• POST: {"direction": direction_to_go}
• GET: {"direction": ..}

3. trigger -- Trigger when a fall is detected

• POST: {"isTriggered": boolean_trigger_data}
