“…Previous research has shown that older people do have unique needs in terms of abilities to perform computer-based tasks successfully (Hawthorn, 2000;Kelly & Charness, 1995). Zajicek (2004) once expressed in her study that there are considerable social and economic reasons why interface designers should rise to the challenge of designing interfaces that are usable by older people. Middle-aged people between the ages of 45 and 54 are some of the important subjects in human-computer interaction (HCI) research areas.…”

Since the 1980s, extensive research has been conducted comparing reading comprehension from printed text and computer screens. The conclusions, however, are not very consistent. As reading from computer screens requires a certain degree of individual technical skill, such variables should be objectively taken into consideration when conducting an experiment regarding the comparison between print and screen reading. This study analyses the difference in the level of understanding of the two presentational formats (text on printed pages and hypertext on computer screens) for people between 45−54 years of age (i.e. "middleaged" adults). In our experimental findings there were no significant differences between the levels of comprehension for print and screen presentations. With regard to individual differences in gender, age group and educational level, the findings are as follows: gender and education effects on print reading comprehension performance were significant, while those on screen reading comprehension performance were not. For middle-aged computer learners, the main effect of age group on both print and screen reading comprehension performance was insignificant. In contrast, linear texts of traditional paper-based material are better for middle-aged readers' literal text comprehension, while hypertext is beneficial to their inferential text comprehension. It is also suggested that hypermedia could be used as a cognitive tool for improving middle-aged adults' inferential abilities on reading comprehension, provided that they were trained adequately to use available computers.

“…number of items to show in group when handling a list of retrieved results, allowing barge-in or not, time in seconds allowed to record messages). In order to improve these capabilities, we propose the incorporation of new user profiles that allow the distinction between young and old people (following the indications suggested by Zajicek (2004) and Wolters et al (2009)) or between men and women. On the other hand, the process of detecting this information could be based on using runtime modules or based on the information provided from the database after the user goes through a previous verification process.…”

Current development platforms for designing spoken dialog services feature different kinds of strategies to help designers build, test, and deploy their applications. In general, these platforms are made up of several assistants that handle the different design stages (e.g. definition of the dialog flow, prompt and grammar definition, database connection, or to debug and test the running of the application). In spite of all the advances in this area, in general the process of designing spoken-based dialog services is a time consuming task that needs to be accelerated. In this paper we describe a complete development platform that reduces the design time by using different types of acceleration strategies based on using information from the data model structure and database contents, as well as cumulative information obtained throughout the successive steps in the design. Thanks to these accelerations, the interaction with the platform is simplified and the design is reduced, in most cases, to simple confirmations to the "proposals" that the platform automatically provides at each stage.Different kinds of proposals are available to complete the application flow such as the possibility of selecting which information slots should be requested to the user together, predefined templates for common dialogs, the most probable actions that make up each state defined in the flow, different solutions to solve specific speech-modality problems such as the presentation of the lists of retrieved results after querying the backend database. The platform also includes accelerations for creating speech grammars and prompts, and the SQL queries for accessing the database at runtime.Finally, we will describe the setup and results obtained in a simultaneous summative, subjective and objective evaluations with different designers used to test the usability of the proposed accelerations as well as their contribution to reducing the design time and interaction.

“…This will be always made under supervision of human tutors in the job social centres where these people are working. In this sense, several meetings have been carried out with dedicated centres as GUREAK, ATZEGI Y TASUBINSA which agree with configuring the behavioural analysis in order to improve, as possible, the integration of these people into work environments (Chia-Fen, 1999;Zajicek, 2004).…”
