Continuous writing the braille code

This paper describes a set of new methods of Braille character recognition with the use of mobile devices such as smartphones. In the frame of the studies, a set of four varying solutions was proposed, further called modes. They are: a simple mode, an acute angle mode, a minimum distance mode, and a scaled mode. Using them, the solutions are designed and implemented for the Android OS platform. The solutions were evaluated using a theoretical model called CLC (curve-line-corner). It was designed to deter-mine the speed of pen stroke gesture, although it is proven that there is no significant difference between pen and finger gestures, thus the results of the model appear to be valid. The model de-composes each stroke into simpler elements, allowing to calculate their production time using proper formulae. Once this is done the performance of the proposed solutions is compared with the existing ones. The results are satisfactory, as the average words per minute count was approximately 25. It is quite high result, although still on par with some of similar solutions.
