Abstract
Nowadays, pen-based mobile computing devices, such as personal digital assistants (PDA) and
other handheld devices are becoming popular. Because of their personal nature, such devices are
expected to conform well to the cultural expectations of their users. However, such devices
originally do not support languages that use Ethiopic scripts for writing, and this makes the users
to communicate with the device in a foreign language. Thus, localization of these devices to those
languages that use Ethiopic script is crucial for getting benefits from the device and for the
utilization of the devices for local applications.
As online handwriting recognition is one of the basic features of pen-computing devices, this
research proposes a model for multi-script (Latin and Ethiopic script) text editing based on online
handwriting recognition. The designed model aims to facilitate users’ task such as note taking,
memo handling, communicating and saving messages with their language of preference. To
reveal the model, a text editing system is developed, and an experiment is conducted to evaluate
the proposed model. The experimental result shows that the system has a recognition accuracy of
88.03% for Amharic basic characters and the usability of the system evaluated to be 93.34%. The
experimental result also shows that a better performance can be attained when the users get
experience of using the stylus (electronic pen).
Key words: A model for multi-script text editing, Ethiopic Online Handwriting
