Women represent 45% of the entire workforce in the United States, but only comprise 26% of the high-tech industry. Early introduction and interest in video games, contributes to computer literacy and self-confidence in terms of computing skills. Socially pervasive gender stereotypes, found in ubiquitous software, specifically games, factor in the alienation of young girls from active participation in computing. Currently marketed gaming software perpetuate this societal bias in the guise of overly-sexualized game avatars, and fail to adequately address documented female gaming preferences. Gender inclusive design is more a pragmatic approach to ameliorating gender bias, than creating a pink box “girl’s game.” Such games cater solely to stereotypical “female” interests, and are uncomfortably close to the concept of “separate but equal.” In the scope of this research a gender inclusive computer role playing game (CRPG) interface was designed and evaluated. The advantage of a CRPG is that it may be played individually or single player mode, as in the prototypic interface, or allow collaborative game play within a smaller group (2-12) when migrated to a multiplayer online environment. Small groups, involved in CRPG collaborative play, may reduce the incidence of online harassment or intimidation by male players, often encountered by experienced female gamers when engaged in Massively Online Multiplayer games. The Xanthia: A Fae’s Battle CRPG, was designed with the intent of studying key female preferences outlined in this research. The design utilized a stylized “cute” but strong female protagonist, featured a compelling storyline, and a backstory narrative. The game broached real world environmental issues with an underpinning of moral dilemma in the guise of good versus evil. Competitive but not combat-centric play was utilized in the game design, which enabled leveling up without the demise of the central protagonist. Fantasy-themed conflict resulted in transformations of both protagonist and antagonists when a change of state occurred during battle, thus eliminating the violence of gory death scenarios. This formative study endeavored to examine the underlying reasons for female underrepresentation in the high-tech and computing fields. The CRPG used in the study, incorporated key gender inclusive game elements found in current literature, in order to acquire insight into female gaming preferences. Two survey instruments were utilized to gather data from 35 female Barry University students, who had disparate gaming experience, comfort with computers, and academic majors. A pre-game questionnaire pertained to motivations for play, level of gaming expertise, and self-perceived comfort with computing. Additional data were gathered regarding access in early childhood to a gaming console or computer in the participants’ childhood homes and the incidence of tinkering. The female sample pool provided CRPG feedback post-game engagement. Examination of survey responses indicated that identification with the central female protagonist was a key element in positive game engagement for the majority of the study’s participants. In general, experienced gamers were more apt to tinker with the hidden features of the game. Experienced gamers also enjoyed competiveness and challenge more than their inexperienced or non-gamer counterparts. The primary component of positive engagement for this female sample group was “fun.” Social interaction was a key motivator for engagement in video game play for the majority of the participants. Empirical data collected from survey instrumentation suggested that individuals who had the easiest access to video game consoles and computing equipment, participated at greater rate in tinkering in childhood. The participants who tinkered, had a higher self-perception of comfort with computing.

With the introduction of new input devices, such as multi-touch surface displays, the Nintendo WiiMote, the Microsoft Kinect, and the Leap Motion sensor, among others, the field of Human-Computer Interaction (HCI) finds itself at an important crossroads that requires solving new challenges. Given the amount of three-dimensional (3D) data available today, 3D navigation plays an important role in 3D User Interfaces (3DUI). This dissertation deals with multi-touch, 3D navigation, and how users can explore 3D virtual worlds using a multi-touch, non-stereo, desktop display. The contributions of this dissertation include a feature-extraction algorithm for multi-touch displays (FETOUCH), a multi-touch and gyroscope interaction technique (GyroTouch), a theoretical model for multi-touch interaction using high-level Petri Nets (PeNTa), an algorithm to resolve ambiguities in the multi-touch gesture classification process (Yield), a proposed technique for navigational experiments (FaNS), a proposed gesture (Hold-and-Roll), and an experiment prototype for 3D navigation (3DNav). The verification experiment for 3DNav was conducted with 30 human-subjects of both genders. The experiment used the 3DNav prototype to present a pseudo-universe, where each user was required to find five objects using the multi-touch display and five objects using a game controller (GamePad). For the multi-touch display, 3DNav used a commercial library called GestureWorks in conjunction with Yield to resolve the ambiguity posed by the multiplicity of gestures reported by the initial classification. The experiment compared both devices. The task completion time with multi-touch was slightly shorter, but the difference was not statistically significant. The design of experiment also included an equation that determined the level of video game console expertise of the subjects, which was used to break down users into two groups: casual users and experienced users. The study found that experienced gamers performed significantly faster with the GamePad than casual users. When looking at the groups separately, casual gamers performed significantly better using the multi-touch display, compared to the GamePad. Additional results are found in this dissertation.

There is a growing societal need to address the increasing prevalence of behavioral health issues, such as obesity, alcohol or drug use, and general lack of treatment adherence for a variety of health problems. The statistics, worldwide and in the USA, are daunting. Excessive alcohol use is the third leading preventable cause of death in the United States (with 79,000 deaths annually), and is responsible for a wide range of health and social problems. On the positive side though, these behavioral health issues (and associated possible diseases) can often be prevented with relatively simple lifestyle changes, such as losing weight with a diet and/or physical exercise, or learning how to reduce alcohol consumption. Medicine has therefore started to move toward finding ways of preventively promoting wellness, rather than solely treating already established illness. Evidence-based patient-centered Brief Motivational Interviewing (BMI) interven- tions have been found particularly effective in helping people find intrinsic motivation to change problem behaviors after short counseling sessions, and to maintain healthy lifestyles over the long-term. Lack of locally available personnel well-trained in BMI, however, often limits access to successful interventions for people in need. To fill this accessibility gap, Computer-Based Interventions (CBIs) have started to emerge. Success of the CBIs, however, critically relies on insuring engagement and retention of CBI users so that they remain motivated to use these systems and come back to use them over the long term as necessary. Because of their text-only interfaces, current CBIs can therefore only express limited empathy and rapport, which are the most important factors of health interventions. Fortunately, in the last decade, computer science research has progressed in the design of simulated human characters with anthropomorphic communicative abilities. Virtual characters interact using humans’ innate communication modalities, such as facial expressions, body language, speech, and natural language understanding. By advancing research in Artificial Intelligence (AI), we can improve the ability of artificial agents to help us solve CBI problems. To facilitate successful communication and social interaction between artificial agents and human partners, it is essential that aspects of human social behavior, especially empathy and rapport, be considered when designing human-computer interfaces. Hence, the goal of the present dissertation is to provide a computational model of rapport to enhance an artificial agent’s social behavior, and to provide an experimental tool for the psychological theories shaping the model.

In 2001, the ACM and IEEE Computing Curriculum stated that it was necessary to address "the need to develop implementation models that are international in scope and could be practiced in universities around the world." With increasing connectivity through the internet, the move towards a global economy and growing use of technology places software internationalization as a more important concern for developers. However, there has been a "clear shortage in terms of numbers of trained persons applying for entry-level positions" in this area. Eric Brechner, Director of Microsoft Development Training, suggested five new courses to add to the computer science curriculum due to the growing "gap between what college graduates in any field are taught and what they need to know to work in industry." He concludes that "globalization and accessibility should be part of any course of introductory programming," stating: A course on globalization and accessibility is long overdue on college campuses. It is embarrassing to take graduates from a college with a diverse student population and have to teach them how to write software for a diverse set of customers. This should be part of introductory software development. Anything less is insulting to students, their family, and the peoples of the world. There is very little research into how the subject of software internationalization should be taught to meet the major requirements of the industry. The research question of the thesis is thus, "Is there a framework for software internationalization that has been validated against industry requirements?" The answer is no. The framework "would promote communication between academia and industry ... that could serve as a common reference point in discussions." Since no such framework for software internationalization currently exists, one will be developed here. The contribution of this thesis includes a provisional framework to prepare graduates to internationalize software and a validation of the framework against industry requirements. The requirement of this framework is to provide a portable and standardized set of requirements for computer science and software engineering programs to teach future graduates.
