Description
The purpose of the study is to gain a better understanding of baby boomers' attitudes toward video chat applications and software based on their user experiences through the measurement of the level of use, usefulness, usability and aesthetics preferences. 133 participants recruited at a local public library and at three senior centers took the survey and 14 respondents were interviewed. The results of the study indicate: (1) Baby boomers have diverse attitudes and experiences in video chatting, but their attitudes do not present a significant difference from those of older generations; (2) Baby boomers' preferences for interface design are influenced by their psychological characteristics rather than physical changes; (3) Family members and close friends are a great resource for assistance and motivation for boomers. The knowledge of motivational factors and barrier factors could help maintain the existing baby boomer users and encourage potential users by providing an improved video chat experience design for them to connect with younger generations. This research could also lead social services into the telehealth age by bridging the gap between a traditional intervention and modern instant video communication.

The International Standards Organization (ISO) documentation utilizes Fitts’ law to determine the usability of traditional input devices like mouse and touchscreens for one- or two-dimensional operations. To test the hypothesis that Fitts’ Law can be applied to hand/air gesture based computing inputs, Fitts’ multi-directional target acquisition task is applied to three gesture based input devices that utilize different technologies and two baseline devices, mouse and touchscreen. Three target distances and three target sizes were tested six times in a randomized order with a randomized order of the five input technologies. A total of 81 participants’ data were collected for the within subjects design study. Participants were instructed to perform the task as quickly and accurately as possible according to traditional Fitts’ testing procedures. Movement time, error rate, and throughput for each input technology were calculated.
Additionally, no standards exist for equating user experience with Fitts’ measures such as movement time, throughput, and error count. To test the hypothesis that a user’s experience can be predicted using Fitts’ measures of movement time, throughput and error count, an ease of use rating using a 5-point scale for each input type was collected from each participant. The calculated Mean Opinion Scores (MOS) were regressed on Fitts’ measures of movement time, throughput, and error count to understand the extent to which they can predict a user’s subjective rating.

Description
Multimedia educational technologies have increased their presence in traditional and online classrooms over the course of the previous decade. These tools hold value and can promote positive learning outcomes but are reliant on students’ degree of cognitive engagement and self-regulation. When students are not cognitively engaged or have low self-regulation capabilities, their interaction with the technology becomes less impactful because of decreased learning outcomes. Building or altering technologies to cognitively engage students is costly and timely; the present study investigates if introducing higher agency roles, to change the role of the student, increases learning outcomes. Specifically, this study investigates if higher agency roles of a designer or teacher enhances cognitive engagement and improves learning when compared to the conventional role of a learner. Improved learning outcomes were observed from the pretest to posttest for the learner, designer, and teacher role. Participants engaged with higher agency roles did not demonstrate more growth from pretest to posttest when compared to the control group, but participants in the teacher role outperformed those in the designer role. Additionally, reading ability did not impact learning gains across groups. While students who engaged with higher agency roles did not achieve greater learning outcomes than students in the control group, results indicate a learning effect across groups. Results of this study suggest that it was underpowered. Further research is needed to determine the extent of the impact that higher agency roles have on learning outcomes.

Today, in the internet-age with global communication every day, it is more important than ever to learn how best to communicate across cultures. However, a review of literature and localization research reveals no studies comparing written communication preferences between cultures using the English language. This gap in research led me to my question–How do localization needs or preferences differ between English-speakers in the U.S. and Canada? To answer my research question, I created a study focused on written communication using a quality measure after consulting the IBM rubric (Hofstede, 1984). I incorporated a demographics questionnaire, a sample document of an Alberta Government brochure, and a survey to measure participant perceptions of quality for use with the sample document. Participants for the study were recruited from Phoenix, Arizona and Edmonton, Alberta, Canada. All participants reviewed the Canada-based sample document and answered the questions from the survey. The survey responses were designed to obtain data on culturally specific variables on contexting, which were critical in understanding cultural differences and communication preferences between the two groups. Results of the data analysis indicate differences in cultural preferences specific to language, the amount of text, and document organization. The results suggest that there may be more significant differences than previously assumed (Hall, 1976) between U.S. and Canadian English-speaking populations. Further research could include a similar study using a U.S.–based document and administering it to the same target population. Additionally, a quality-based measure could be applied as a way of understanding other cultures for localization needs, since inadequate localization can have an adverse impact on perceptions of quality.

Description
Providing the user with good user experience is complex and involves multiple factors. One of the factors that can impact the user experience is animation. Animation can be tricky to get right and needs to be understood by designers. Animations that are too fast might not accomplish anything and having them too slow could slow the user down causing them to get frustrated.
This study explores the subject of animation and its speed by trying to answer the following questions – 1) Do people notice whether an animation is present 2) Does animation affect the enjoyment of a transition? and 3) If animation does affect enjoyment, what is the effect of different animation speeds?
The study was conducted using 3 prototypes of an application to order bottled water in which the transitions between different brands of bottled water were animated at 0ms, 300ms and 650ms. A survey was conducted to see if the participants were able to spot any difference between the prototypes and if they did, which one they preferred.
It was found that most people did not recognize any difference between the prototypes. Even people who recognized a difference between the prototypes did not have any preference of speed.

Description
In the United States, seasonal influenza is responsible for enormous medical costs and lost earnings as well as thousands of deaths. Medical masks are effective non-pharmaceutical preventions for minimizing the spread of illness in the event of an influenza outbreak. However, people in the United States rarely wear face masks the way many people in Asian countries do.
In a previous study of public response to the 2009 influenza A H1N1 pandemic, 71% of United States respondents supported the recommendation to wear a mask during the flu outbreak, while only 8% of respondents reported they wore a mask in public to protect themselves from getting sick. What are the factors that cause this gap? The purpose of this exploratory study is to identify barriers to the wearing of masks among adults in the United States.
The research was conducted through an online survey of 84 American residents via the Survey Monkey Audience service to collect their opinions on influenza, mask-wearing, and the perceived barriers to wearing face masks for flu prevention. The results are presented in the descriptive analysis and the non-parametric analysis.
The results showed a barrier against social interaction is a significant factor (p=0.003) regarding the impact between flu experience and the perceived barriers. The participants believed mask-wearing may lead other people difficult to perceiving their feelings. Regarding the relationship between mask-wearing experience and the perceived barriers, there were significant differences in perceived benefits (p=0.028), perceived risks (p= 0.003), and social value (p=0.021). Participants who have had worn masks had perceived higher benefits of mask-wearing, higher risks of catching the flu, and a higher agreement of importance to protect other people from getting the flu from them. The most common perceived barrier among the participants is product satisfaction. 85.71% of the participants agreed that wearing face masks is uncomfortable. 80.95% of the participants agreed with the importance to wear face masks as it protects other people from getting the flu from them, but only 37.5% of the participants with flu history had worn face masks.
By examining barriers to the wearing of masks for influenza prevention, this study can assess public willingness to adopt personal prevention behaviors and provide information for related policies in the future.

Description
Social interaction among people in public spaces is an important way to strengthencommunity ties. Therefore, this study seeks to shed light on the significant role of interior
design in increasing the quality of exhibition-built environments. Which in turn affects
human behavior, which may lead to enhanced communication between visitors. In
addition, the results guide the designer to the most effective design features to build spaces
that help social interaction. The research took the Biennale of Islamic Arts in Jeddah, Saudi
Arabia, as a case study representing contemporary religious exhibitions. It investigates the
impact of lighting, furniture layout, and space planning on interactive behavior among
visitors. And these aspects will be measured by applying the triangulation method: field
observation, semi-structured interviews, and survey, spread randomly, among biennial
local and international adult visitors (n = 114, women n=71 and men n=43). The results
illustrate that employing design features around users’ preferences (Human-centered
design) within public interior spaces influences the visitors’ behavior and willingness
toward social interaction.
