Abstract

This study is part of the new branch of the domain MMI / HCI. The research has investigated the correlation between Vocational Preferences of the user and his expectations from a given computer application.

This research is based on the assumption that the various applications are created in order to fulfill the needs of various domains. According to Holland’s research (1960), every such domain is populated by professionals belonging to a group with known preferences, which categorize the professional tendencies into six vocational groups: Realistics, Investigators, Artistics, Socials, Enterprise and Conventionals.

In order to study this correlation, an internet questionnaire was constructed, that determines the study participant’s belonging to a specific vocational group profile and his perspective toward the way in which he perceives / understands the computer and its various applications. 15 computer applications were examined: text editing, message and chat applications, media editing applications, sharing applications, movie and music players, search engines, anti virus and protection applications, news sites, community environments, price comparison sites, setting and organizations application, computer games, the unique application in work, the main computer and its operating system and the email application.

The viewpoints examined were chosen from the work of John Kamasgard (1986). He described four common perspectives from which users understand the computer application: as a Mediator between people, as a Partner to accomplish a mission, as a Machine of a system, and as a Tool Box.

The questionnaire of about 400 questions was completed by 101 subjects chosen according to their vocations, with the aim of creating a database that can be equally divided into the six above-mentioned types.

Analysis of the observations shows the possibility to characterize the various viewpoints regarding the computer application on the part of the users, and suggests two models to describe the correlation between the users’ profiles and their perspectives regarding the computer applications. The first model is a single axis model, which concerns with the way users see the computer application at the present time and how they expect the computer application to be in the future. The second model places on a two-dimensional model matrix both the users’ viewpoints and the also the various computer applications.

According to the first model, there is a similarity among the different users, on the continuum between what is currently available and what would be desirable.

According to the second model certain computer applications are preferred by the users as accordance to the user’s group perspectives.
