  • Modúlos de diagnóstico y de tratamiento.
  • constatamos que los alumnos han sentido un interés considerable por la actividad (78,6% de acuerdo o muy de acuerdo) y que este se ha mantenido durante el desarrollo de la misma (64,3 % de acuerdo o muy de acuerdo). Así mismo, la mayor parte de los alumnos manifiestan claramente que la actividad les fue divertida (humor, 85,7%) y satisfactoria (felicidad, 71,4%). Los sentimientos menos frecuentes fueron los de hostilidad, ya sea hacia sus compañeros de equipo o sus rivales. No obstante, confiesan haberse sentido ocasionalmente frustrados e incapaces de superar ciertos obstáculos.

    16. 16. Gender HCI & UCD <ul><li>Gender HCI (*) is a subfield of HCI that focuses on the design and evaluation of interactive systems for humans, with emphasis on differences in how males and females interact with computers. </li></ul><ul><li>The main areas of interest are: </li></ul><ul><ul><li>Effects of confidence and self-efficacy on interactions with software </li></ul></ul><ul><ul><li>Design of gender-specific software </li></ul></ul><ul><ul><li>Design of interfaces and to study its effect. </li></ul></ul><ul><ul><li>Design of gender-neutral problem-solving software. </li></ul></ul><ul><ul><li>(*) Beckwith, L. and Burnett, M.

    17. 17. Gender HCI & UCD <ul><li>Researchers of Gender HCI had studied the field from different perspective: </li></ul><ul><ul><ul><li>Preferences and opinions of actors and cognitive differences between males and females has been studied (Arroyo, 2003, Arroyo et al, 2006; Bandura, 1977, Halpern, 2000). </li></ul></ul></ul><ul><ul><ul><li>Stimulus’ influence and attraction of technological tools has been analyzed (Beckwith 2005, Beckwith et al, 2004, 2006, Burnett et al, 2004, Beckwith et al, 2006). </li></ul></ul></ul><ul><ul><ul><li>Validators to analyze the semantic structure of web pages and videogames has been developed (Casell y Jenkins, 1998, Van Slyke et al, 2002). </li></ul></ul></ul><ul><ul><ul><li>There are several studies about effects of software interfaces on different user profiles (Dillon and Watson, 1996, Kucian et al, 2005, Nuñez, 2003). </li></ul></ul></ul>
    18. 18. <ul><li>Until recently, research has not considered whether the design of problem-solving software affect males and females differently. </li></ul><ul><li>Attention to gender differences is important in the design of software. </li></ul><ul><li>Evidence from other domains, such as psychology and marketing, strongly suggests that females process information and problem solve in very different ways that males do. </li></ul><ul><li>Some research has shown that software is unintentionally designed for males. </li></ul><ul><li>Needs of half the population for whom the software is intended are potentially being ignored. </li></ul>Gender HCI & UCD <ul><li>McDonough, J.

    19. 19. <ul><li>Example: Videogames </li></ul><ul><li>Since the design programs of today focus on user-centered design, and users of video games are increasingly female, then perhaps the way things are done in video game design has changed over the past 10 years. But not. </li></ul><ul><li>The people designing the games are still mostly male. </li></ul><ul><ul><li>Sony Online Entertainment announced a scholarship program aimed at getting more girls into video game design because there still aren’t very many women game designers. </li></ul></ul><ul><li>The content of many video games are still male-oriented. </li></ul><ul><ul><li>The list of best- selling video games are all mostly masculine themes. </li></ul></ul><ul><li>So, it appears that the video game design industry hasn’t really changed that much at all over the past 10 years, even though their users have. </li></ul>Gender HCI & UCD
    20. 20. <ul><li>We need more empirical evidences about how males and females interact with computers </li></ul><ul><ul><li>Human factors (cognitive, phisical, ergonomic, etc.) </li></ul></ul><ul><ul><li>Categorization of information (gender differences in the labeling and structuring of information); </li></ul></ul><ul><ul><li>How women think the task on the web ; </li></ul></ul><ul><ul><li>How women think on design and style’s guide ; and </li></ul></ul><ul><ul><li>How women cooperate, collaborate or interact on the net. </li></ul></ul><ul><li>Another important need is to elaborate a recomendations guide about gender differences to software designers. </li></ul>Gender HCI & UCD
    21. 21. Gender HCI & UCD <ul><li>Some findings on gender differences research : </li></ul><ul><ul><li>Differences on information processing, comunication and problem solving applied to software design. </li></ul></ul><ul><ul><li>Females has specif skills and use preferences on software in mathematics, programming, videogames, etc. </li></ul></ul><ul><ul><li>Related with user interface design or usability (*) </li></ul></ul>(*) Yu-chang Hsu (2007).
