Situations present themselves in which someone needs to navigate inside of a building, for example, to the exit or to retrieve and object. Sometimes, vision is not a reliable sense of spatial awareness, maybe because of a smoky environment, a dark environment, distractions, etc. I propose a wearable haptic device, a belt or vest, that provides haptic feedback to help people navigate inside of a building that does not rely on the user's vision. The first proposed device has an obstacle avoidance component and a navigation component. This paper discussed the challenges of designing and implementing this kind of technology in the context of indoor navigation, where GPS signal is poor. Analyzing accelerometer data for the purpose of indoor navigation and then using haptic cues from a wearable haptic device for the navigation were explored in this project, and the device is promising.

Description
Millions of people every day log onto their computers to play competitive games with others around the world. Each of these players has their own unique personality and their own reasons for playing. To explore the relationship between player personalities and gameplay, this study asked participants to report their Myers-Briggs sixteen personality types and complete a survey that asked them questions about their behavior while games playing competitively online including their preferred in-game archetype and questions about how they interact with other players online. The survey also included the Grit Scale test, which which was intended to explore players' perseverance. Nearly 700 people participated in the study and all responses were analyzed based on their Myers-Briggs' personality type. While this study revealed that Myers-Briggs' personality type alone cannot determine a player's mindset while playing online, it was found to be an indicator of how they feel about socializing with others online. The implications of these results are discussed in this paper.

We discuss processes involved in user-centric security design, including the synthesis of goals based on security and usability tasks. We suggest the usage of implicit security and the facilitation of secureuser actions. We propose a process for evaluating usability flaws by treating them as security threats and adapting traditional HCI methods. We discuss how to correct these flaws once they are discovered. Finally, we discuss the Usable Security Development Model for developing usable secure systems.

Description
Over the course of computing history there have been many ways for humans to pass information to computers. These different input types, at first, tended to be used one or two at a time for the users interfacing with computers. As time has progressed towards the present, however, many devices are beginning to make use of multiple different input types, and will likely continue to do so. With this happening, users need to be able to interact with single applications through a variety of ways without having to change the design or suffer a loss of functionality. This is important because having only one user interface, UI, across all input types is makes it easier for the user to learn and keeps all interactions consistent across the application. Some of the main input types in use today are touch screens, mice, microphones, and keyboards; all seen in Figure 1 below. Current design methods tend to focus on how well the users are able to learn and use a computing system. It is good to focus on those aspects, but it is important to address the issues that come along with using different input types, or in this case, multiple input types. UI design for touch screens, mice, microphones, and keyboards each requires satisfying a different set of needs. Due to this trend in single devices being used in many different input configurations, a "fully functional" UI design will need to address the needs of multiple input configurations. In this work, clashing concerns are described for the primary input sources for computers and suggests methodologies and techniques for designing a single UI that is reasonable for all of the input configurations.

Smartphones have become increasingly common over the past few years, and mobile games continue to be the most common type of application (Apple, Inc., 2013). For many people, the social aspect of gaming is very important, and thus most mobile games include support for playing with multiple players. However, there is a lack of common knowledge about which implementation of this functionality is most favorable from a development standpoint. In this study, we evaluate three different types of multiplayer gameplay (pass-and-play, Bluetooth, and GameCenter) via development cost and user interviews. We find that pass-and-play, the most easily-implemented mode, is not favored by players due to its inconvenience. We also find that GameCenter is not as well favored as expected due to latency of GameCenter's servers, and that Bluetooth multiplayer is the most well favored for social play due to its similarity to real-life play. Despite there being a large overhead in developing and testing Bluetooth and GameCenter multiplayer due to Apple's development process, this is irrelevant since professional developers must enroll in this process anyway. Therefore, the most effective multiplayer mode to develop is mostly determined by whether Internet play is desirable: Bluetooth if not, GameCenter if so. Future studies involving more complete development work and more types of multiplayer modes could yield more promising results.

Description
Web-application development constantly changes \u2014 new programming languages, testing tools and programming methodologies are often proposed. The focus of this project is on the tool Selenium and the fairly new technique known as High Volume Automated Testing (HVAT). Both of these techniques were used to test the Just-in-Time Teaching and Learning Classroom Management System software. Selenium was used with a black-box testing technique and HVAT was employed in a white-box testing technique. Two of the major functionalities of this software were examined, which include the login and the professor functionality. The results of the black-box testing technique showed parts of the login component contain bugs, but the professor component is clean. HVAT white-box testing revealed error free implementation on the code level. We present an analysis on a new technique for HVAT testing with Selenium.

Cravingz is a web-based application that allows users to learn the maximum number of food items that they can purchase at a restaurant within a defined personal budget. We created two versions of this web-based application and asked 40 users to perform an A/B test to determine which version provides the best user experience in terms of efficiency and performance. Users who participated in this study completed a set of tasks to test these applications. Our findings demonstrate that users prefer a web application that does not require them to input data repeatedly to view combinations for multiple restaurants. Although the version which required reentry of data was more visually-pleasing, users preferred the version in which inputting data was a one-time task.

Description
In this study, the implementation of educational technology and its effect on learning and user experience is measured. A demographic survey, pretest/posttest, and educational experience survey was used to collect data on the control and experimental groups. The experimental group was subjected to different learning material than the control group with the use of the Elements 4D mobile application by Daqri to learn basic chemical elements and compounds. The control group learning material provided all the exact information as the application, but in the 2D form of a printed packet. It was expected the experimental group would outperform the control group and have a more enjoyable experience and higher performance. After data analysis, it was concluded that the control group outperformed the experimental group on performance and both groups has similar experiences in contradiction to the hypothesis. Once the factors that contribute to the limitations of different study duration, learning the application beforehand, and only-memorization questions are addressed, the study can be conducted again. Application improvements may also alter the future results of the study and hopefully lead to full implementation into a curriculum.

Description
Technical interviews have become the standard for assessing candidates for software development roles. The purpose of this study is to determine whether time constraints impact the performance of individuals on HackerRank coding assessments. During the surveys and HackerRank assessment, subjects wore two physiological sensors: a galvanic skin response bracelet, Shimmer3+GSR that measures emotional intensity and an EEG headset, B-Alert X24 that measures cognitive workload, engagement, and distraction. Subjects were also monitored by external sensors, such as an eye tracker to measure visual attention and by a facial-based emotion recognition system through a webcam to measure their visual attention and emotions. Through these metrics, as well as a Big Five personality demographic survey and mental demand survey, the study examines the difference in performance between strictly timed assessments and timed assessments with time to revise.

Description
Physical activity has been shown to have lasting impacts on one's physical and mental wellbeing. The purpose of this study was to further this understanding by examining the effects of high team-based exercise on cognition and perception, and the role of gender and emotion in those differences. Participants were fitted with a biometric measure system (EEG headset, GSR bracelet, face-based emotion recognition system, and eye tracking system), while they engaged in diverse tasks, such as: a demographic survey, self-report of emotional intelligence test, tower of London test, motor speed test, viewing product and experience marketing videos, working memory capacity battery, completion of an online task on online store, and a system usability survey. By participating in this series of assessments, individuals of low and high exercise levels had diverse metrics collected which yield a view into their cognition and perception. This study found that gender and emotion does play a role in the effect on cognition and perception of individuals who exercise in team-based settings. Utilizing Welch's t-test, female participants of high team-based exercise were found to be less engaged during the tower of London test and a marketing video about baseball products that shows different experiences of the game and more distracted during a marketing video about baseball products that shows a particular baseball product than male participants of high team-based exercise during the same same exact test and marketing videos.
