Touchscreen Software Keyboard for Finger Typing [chapter]

Kentaro Go, Yuki Endo
2008 Human Computer Interaction: New Developments  
It is easy to record a sequence of typed characters, predicting subsequent characters based on a dictionary, and showing a menu of candidate words.  ...  The device sizes are categorizable into three groups: small, medium, and large. Small touchscreen devices include mobile and smart phones, Personal Digital Assistants (PDAs), and handheld computers.  ...  Each chapter gives the reader background information on a subject and proposes an original solution.

2012 Proceedings of the 17th ACM annual conference on Innovation and technology in computer science education - ITiCSE '12  
We propose that computer programming, and thus the teaching of programming, can and should be done directly on the mobile devices themselves, without the need for a separate PC or laptop to write code.  ...  Right now, in 2012, we are in the middle of another technology shift: instead of using PCs and laptops, mobile devices are becoming more prevalent for most everyday computing tasks.  ...  We predict that moving away from a keyboard, a device that allows very precise entry of around 100 different characters to a touchscreen typical for mobile devices will again influence how the program  ...

Augmenting Around-Device Interaction by Geomagnetic Field Built-in Sensor Utilization

Sandi Ljubic, Franko Hržić, Alen Salkanovic, Ivan Štajduhar
2021 Sensors  
In this paper, we investigate the possibilities for augmenting interaction around the mobile device, with the aim of enabling input techniques that do not rely on typical touch-based gestures.  ...  Namely, text entry is achieved by discrete positioning of the magnet within a keyboard mockup, and free-move pointing is enabled by monitoring the magnet's continuous movement in real-time.  ...  Touch-based interaction, on the other hand, comes with specific drawbacks due to the limited form factor of touchscreen devices and the effects of the well-known fat finger syndrome.  ...
