1. Remotely Controlled Communication and
Control System for Limited Mobility
Individuals
Abstract:
There is a great deal of interest in furthering the capabilities of smart homes and
intelligent environments. Our contribution to this research field is to create a system for use by
individuals that may have temporary or permanent limitations in their mobility while they are
recovering in the hospital as well as discuss open source options for a home version of the
system for remote control of the environment as well as social interaction. There are several
solutions available for the control of devices. Design improvements to a remotely controlled
system for patients with limited mobility are described. Transition to an open source Android
operating system is discussed for long-term use in the home environment. Prototype
configurations for use in the hospital and home environment are introduced.
Existing System:
In existing system motion sensors were used to control devices by a limited mobility
person. Since it has limited application we are using an android mobile for our applications.
Proposed System:
A system for controlling a room’s environment by a person with limited mobility and
hand function is described with detailed analysis of design alternatives. The long-term goal is to
reduce the anxiety of individuals with significant mobility limitations by providing them with
communication and control capabilities. The proposed system uses Bluetooth as a
communication medium between android mobile and the devices. The users with limited
mobility can use their mobile to control the home devices. Atmel’s AT89C51 executes command
received from the mobile through Bluetooth. The user can give input from the mobile to switch
the devices ON or OFF. The android application has been developed to establish a connection
with the control unit and mobiles Bluetooth. Devices will be controlled using electromechanical
type relays by microcontroller.
