The document describes a motion-based message conveyer system for paralytic disabled persons. The system uses an Arduino board, accelerometer, LCD display, voice module, and speaker. Gestures detected by the accelerometer will play corresponding recorded voice messages on the speaker to communicate basic needs like food, water, or medicine. The system provides a low-cost way for paralytic patients to communicate their needs through simple gestures. It aims to improve independence and quality of life for those unable to communicate verbally.

3. OBJECTIVE
 The main aim of the project is to implement a low cost reliable system which will help
to establish communication between paralytic or disabled patients and other people.
 MEMs and APR based announcement system for patients using Arduino is a project
that uses gestures to play recorded voice messages for physically challenged people.

4. EXISTING METHODS
• Monitoring system make it easier for doctors to collect and observe a patient’s vitals,
there aren’t many options for actual verbal communication for paralytic and disabled.
• They cannot communicate their basic needs with their family members.

5. ABSTRACT
• Physically challenged people have no specific electronic devices to communicate their
needs using gestures
• This project proposes a MEMS and APR based announcement system for patients.
• A patient can easy send messages by just tilting an accelerometer connected to the body
• The system detects the patient's gestures and plays a recorded voice message based on
the gesture.
• The system can be used in homes, hospitals, and public places.

Architectural Design For Proposed System

7. Arudino UNO:
Arudino has inbuilt Analog to digital converter. It has a 16 MHz ceramic resonator, 14 digital
input/output pins ,6 analog inputs, a USB connection, a power jack, an ICSP header, and a reset
button.The ATmega328 has 32 KB ROM. It also has 2 KB of SRAM and 1 KB of EEPROM
(which can be read and written with the EEPROM library.
The operating voltage is 5v and supply voltage is 7 to 20v.
Arduino boards are able to read analog or digital input signals from different sensors and turn it
into an output such as activating a motor, turning LED on/off.

8. MEMS(ADXL345):
 This ADXL345 Accelerometer module consists of an ADXL345 Accelerometer IC, Voltage
Regulator IC, Level Shifter IC, resistors, and capacitors in an integrated circuit.
 ADXL345 is a 3-axis accelerometer but we use two axis that senses both static acceleration (due
to gravity) as well as dynamic acceleration (due to motion or shock).
 It converts mechanical energy into electrical energy. So, it can be used as a tilt sensor or to detect
free fall. This sensor works with I2C and requires 5v of voltage.It is also called as gyroscope.

9. Voice module(APR33A IC):
• The APR33A3 device is a single-chip voice recording, non-volatile storage, and
playback capability for 40 to 60 seconds.
• The operating voltage range of this 3v-6.5v.
• It can record 8 voices but we use 4 of it and contains a condense mike.
• It User-friendly, easy-to-use operation and Low power consumption.

10. 16X2 LCD:
• Liquid crystal display is very important device in embedded system. It offers high
flexibility to user as he can display the required data on it.
• A liquid crystal display (LCD) is a thin, flat electronic visual display
• Operating voltage is 4.7v to 5.3v and operating current is 1mA.
• It works in both 8-bit and 4-bit mode.
• It consumes low power.

11. Regulated power supply:
• A regulated power supply ensures that the output current remains constant,even if the input
changes,by converting unregulated AC to DC.
• With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable
voltage (or less often current), to a circuit or device that must be operated within certain
power supply limits.
• The output from the regulated power supply may be alternating or unidirectional, but is
nearly always DC (direct current).
• The primary advantage of RPS is that it provide a stable and constant output voltage or
current which is crucial for the proper functioning of electronic circuits.

12. Experimental Results includes output photos of project
The paralytic disabled people can communicate their basic needs with their family/nurse.The
output displays on the LCD.It sounds message through speaker.

17. Comparision with existing system
• Among the large number of paralytic disabled peoples , very few actually focus on helping
patients with disabilities to communicate.
• Although monitoring systems make it easier for doctors to collect and observe a patient's
vitals, there aren't many options for actual verbal communication for disabled patients.
• The main aim of the project is to implement a low cost reliable system which will help to
establish communication between paralytic or disabled patients and other people.
• A patient can easy send messages by just tilting an accelerometer connected to the body.
• The system detects the patient's gestures and plays a recorded voice message based on the
gesture.
