devnagari text | Indic text input presents a unique challenge in the field of keyboard |
entry, gesture | design because of the number of standalone characters, conjuncts, matras, |
keyboard (GKB), | and symbols. It poses a huge challenge to the HCI practitioners to |
matras, modifier, | accommodate the humongous array of Devnagari characters in a |
syllable, IMEs | keyboard. Solutions for input in Devnagari scripts using a physical |
| keyboard have been around for a while but none of them have emerged as |
| a standard mechanism due to several usability related concerns. In this |
| paper we have described the design of a new gesture based keyboard, |
| which has a dual input mode 1. Gesturing 2. Tapping. The "gesture |
| keyboard" concept is based on partial hand writing recognition as well as |
| |
| supports tapping for getting the base consonants and some symbols, |
| while it also recognizes handwritten matras as per handwriting |
| recognition methods. This paper also reports the findings of the user |
| study, which was carried out to find the optimum sizes of the keys and |
| layouts. |
