The current state of computer algebra system on tablet devices

Infty project[1] developed and released some useful software including InftyReader – an OCR system for mathematical documents. InftyEditor is one of the products developed by Infty project, and is a mathematics typesetting tool. The author, a core member of Infty project, built into InftyEditor a computing function for mathematical expressions[2]. In 2003, AsirPad[3], a computer algebra system with a handwriting interface on PDA, was developed using the technology of InftyEditor. AsirPad can communicate with Risa/Asir[4] through OpenXM protocol[5], and calculate mathematical expressions inputted by handwriting. This is an application for Zaurus that is a PDA with 400MHz CPU, 64MB memory, Linux OS, 3.7inch VGA screen and the weight 250g. The mainstream of the current mobile devices is shifting to smartphones or tablet devices and some computer algebra systems for these platforms are developed. In this article we explore the current state of computer algebra system on tablet devices.
