Abstract:
The idea of combining the effective visualization techniques to enhance usability among
young learners is becoming a problem in human computer interface (HCI). Although
several visualization techniques have been established for user interfaces development,
the integration of these visualization techniques has not been done. The research
enhanced usability through identification of the appropriate visualization techniques for
young learners and integrated them to develop an appropriate user interface for the One
Laptop Per Child (OLPC) project in Kenya. Both tree visualization techniques and the
category visualization techniques were integrated in creating an efficient user interface
for young learners. The user interface created was implemented and evaluated through
interaction with young learners and the results were positive since optimal information
dissemination was observed.
