Abstract: PDAs have become increasingly popular due to advances and availability of wireless services. The desire for effective text entry on portable devices have also increased with the advent of virtual keyboard being as one of the major contributors to the sudden burst of research in handheld device text entry techniques. Virtual keyboard is the one which employs on screen keyboard where programmable graphical buttons are handling the input activity based on the event triggered on them. In order to design virtual keyboard one has to consider nature of the language where by the text entry mechanism is achieved. In this project the Amharic language is chosen for the layout of the virtual keyboard to be designed. Amharic is the working language of the federal government of Ethiopia and is spoken and written as a first or second language in many parts of the country. The abundance of characters in Ethiopic script brings a challenge for developing Amharic virtual keyboard on handheld devices. The objective of this project is to address the design and implementation of the virtual keyboard for Amharic text entry on PDA devices. For this purpose the layout design for Amharic virtual keyboard is proposed and an Amharic virtual keyboard is developed by taking inherent challenge of Amharic language in to account. The developed virtual keyboard is implemented for a simulator of an Android operating system PDA. Android OS is selected for the implementation considering its possible future popularity and usage for mobile handheld devices such as PDAs, smart phones, mobile phone etc. The system is also designed in such a way that Amharic and English virtual keyboards can be switched to enable multi-script text entry.
