Optimisation of the Selection Set Features for Scanning Text Input
نویسندگان
چکیده
Scanning is one of the most popular text input methods for people with severe movement restrictions due to diverse kinds of disabilities. It is frequently used to input messages into communication systems, such as text-tovoice translators in order to maintain conversations. Nevertheless, the rate of text production usually obtained is very slow. For this reason, every effort to save time and optimize communication speed is welcome. In this way, this paper presents a study on the influence on the character input rate of diverse parameters related to the matrix that contains the selection set, such as shape, size, number of dimensions and layout of the selectable items. Its purpose is to extract a set of guidelines to design efficient input systems well adapted to the user, based on the scanning of items and its selection by means of one switch or push-button.

Image retrieval is an important research field which has received great attention in the last decades. In this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. For text-based features, keywords and for content-based features, color and texture features have been used. Query in this system contains some keywords and an input...
متن کاملFeature selection for a DTW-based speaker verification system
Speaker verification systems, in general, require 20 to 30 features as input for satisfactory verification. We show that this feature set can be optimised by appropriately choosing proper feature subset from the input feature set. This paper proposes a technique for optimisation of the feature sets, in an Dynamic Time Warping (DTW) based text-dependent speaker verification system, to improve fa...
