Two Characters per Stroke -
نویسنده
چکیده
A novel pen-based text entry technique, which yields two characters with one stroke, is introduced, and the results of its investigation are presented. The 2CPS technique is implemented as a gesture-based user interface on a QWERTY soft keyboard. Eight participants completed eight text entry trials on a fully functional version of this stroke-based system on a Pocket PC. The difference between the means of the eighth trial and the first trial demonstrated a substantial improvement of 41%. In spite of this evident progress on the learning curve, the participants’ mean rate for the eighth trial was a mere 5.6 wpm. The reasons behind the results are discussed and future improvements to the system are proposed.

In this paper a new method for the online recognition of handwritten Persian characters has been proposed which uses a set of simple features and Support Vector Machine (SVM) as a classifier. The task of preprocessing allows us to equalize feature vectors from different characters. This algorithm is implemented in two steps. In the first step, input character is classified into one of eighteen ...
متن کاملPair-wise discrimination based on a stroke importance measure
The pair-wise discriminator is a binary classi.er that veri.es the outcome of the recognizer if it belongs to a class in a pre-de.ned confusion pair database. It is di0cult to discriminate a pair of characters that are very similar in shape except for a small di2erence, because the small di2erence can be overridden by the writing variation. This paper proposes a pair-wise discrimination method ...
متن کاملA Run-Length Coding Based Approach to Stroke Extraction of Chinese Characters
Traditional stroke extraction approach usually adopts thinning technique as the preprocessing method in obtaining the skeletons of Chinese characters. However, thinning may produce spurious branches and multiple fork points at junctions. Such distortion will make stroke extraction process more complicate and unreliable. This paper proposes a novel run-length-based stroke extraction approach wit...

In this work, we aim to transform handwritten Chinese characters into calligraphy style characters on a stroke-by-stroke basis. We extracted strokes from a set of handwritten characters by identifying the primary orientation of each stroke. We then adopted autoencoder and self-organizing maps to cluster the extracted strokes into 100 different groups. Using the neural networks obtained, we clus...
متن کاملText Entry Method for Reduced Keypads using One Key Stroke and One Column Stroke per Character
Proposed is a new method to enter text using a reduced keypad, as is typically found on telephones, with particular extensions for one with a display window above it, as is typically found on mobile phones. In this method each of the most commonly used characters is entered by selecting two keys in succession. The so-called KC-method may be programmed into a conventional mobile phone without an...
