ABSTRACT
Text entry system can be found commonly in modern computer and mobile devices
such as smartphone and tablet. Despite this, these text entry systems are not easily
accessible by handicaps. The major problem with the normal text entry system such as
the “QWERTY” keyboard, it would be very difficult for the handicaps to input the keys.
To use an ordinary keyboard, major hand movement is needed for them because the
keyboard contains over a hundred keys. They might have to move across the keyboard
to enter the desired keys. Hence, the usage of a keyboard for the handicaps is not
recommended especially for those who suffered from motor disabilities.
A new wireless-based text entry system is described in this research to help the
handicaps to ease their lives and input text faster. This new text entry system will be
much smaller than the traditional keyboard. In addition, this system would be designed
to be portable, lightweight, long operating hour and user-friendly. Besides, this system
enables the handicaps input text efficiently with minimum hand movement. Besides,
the handicaps will only require one hand to hold the equipment and one finger to
interact and to input text.
This equipment will be built using the Printed Circuit Board (PCB), the Arduino Uno
board (CT-UNO) and a Bluetooth module. PCB is used instead of using breadboard is
to keep the device with the minimum wires. Besides, the Bluetooth is used to ensure
the device can communicate to the computer wirelessly.
The algorithm used in this text entry system is Press-Drag-Release algorithm where the
user first pressed on the infrared text entry board, then the user drags the finger around
the board to choose the letter and then release. Next, the respective letters will be printed
on the computer. As a result, the user only needs to perform 3 steps to input a letter.
Apart from inputting letter to the computer, the text entry system is also a combination
of keyboard and mouse where the user can use the text entry system as a mouse and
navigate through the computer like the ordinary mouse.
The average entry rate of this text entry system is about 5 WPM. The result is better
than some of the system that designed for the handicapped.
