Description

ABSTRACT

Eyechart is used by the Hospitals especially eye specialty hospitals, to check the vision of the patient, which contains both alphabets and numbers in decreasing order of sizes to check the vision of the patient. In Hospitals, they used to change the display manually by changing the board or by using the high expensive system to change the display. Here we are proposing a newq method to the change the eyechart character by using Remote control by having the core system as Raspberry Pi.

BLOCK DIAGRAM DESCRIPTION

In the above block diagram, Raspberry Pi is used as the centralized system, where the IR receiver is connected serially to the Raspberry Pi, to receive the signal from the Remote. Then Monitor is connected to the Raspberry Pi using HDMI to VGA convertor, where the Eyechart is displays as each character at once.

 

PROJECT DESCRIPTION

IR Remote, which is held by the Doctor, to change the eyechart as character by character remotely. These commands are received by the IR receiver, which is connected serially on to the Raspberry Pi. Whenever we pressing the button in the remote the each character of eyechart is loaded in the monitor to make the patient to view. By their vision, problem can be identified based on their visibility. Which the system becomes wireless so that it makes this system as efficient.

 

HARDWARE REQUIRED

  • Raspberry Pi
  • Power Adapter
  • HDMI to VGA converter (optional, when connecting to Monitor)
  • IR Remote
  • IR receiver

SOFTWARE REQUIRED

  • Raspbian Jessie OS
  • SD Card Formatter
  • Win32 Disk Imager (or) Etcher

 

LIBRARIES USED

  • RPi.GPIO as GPIO (To access GPIO Pins of Raspberry Pi)
  • Time library (For Delay functions)
  • Serial

 

CONCLUSION

This Eye charts are used in every optical, which this system is used to change the characters remotely used by this system.
