This paper presents simulation model that estimates average text entry, time and average number of user Inputs per character for an unambiguous virtual keyboard with different character predictors The simulation is focused on VK operated by binary user inputs (ON OFF) that could come from physical buttons, wink detection systems, etc The model allows us to use different predictors (k-grams, n-grams or any combination of them), prediction list scanning methods, lengths of prediction list and prediction turn-on delays The simulation give us optimal list length and prediction delay for different predictors and scanning methods

This In this paper, a system architecture that can be adapted to an individual’s motor capacity and preferences, to control a computer is presented. The system uses two different transducers based on the emission and the reflection of infrared light. These let to detect of voluntary blinks, winks, saccadic or head movements and/or sequences of them. Transducer selection and operational mode can be configured. The signal provided by the transducer is adapted, processed and sent to a computer by external hardware. The computer runs a row-column scanned switch-controlled Virtual Keyboard (VK). This sends commands to the operating system to control the computer, making possible to run any application such as a web browser, etc. The main system characteristics are flexibility and relatively low-cost hardware.

In this paper we present the integration of multimedia contents in the teaching of Digital Electronic Circuits and Computer Structure, of the first course of Computer Engineering at the University of Seville. Different tools for screenshot and video recording have been used for the preparation of audiovisual material, integrated in the learning platform currently used at the University of Seville.

ABSTRACT In this paper, a learning project is explained which is being carried out at the school of computer science at the University of Seville. The aim is that students receive knowledge of assistive technologies when in fact there is no this discipline in our curricula. So the best way, it is programming final studies projects in this field. We want to make the projects have a real application and can solve difficulties that children with Cerebral Palsy have in their daily activities in the school.
