Description
This thesis is an initial test of the hypothesis that superficial measures suffice for measuring collaboration among pairs of students solving complex math problems, where the degree of collaboration is categorized at a high level. Data were collected
in the form of logs from students' tablets and the vocal interaction between pairs of students. Thousands of different features were defined, and then extracted computationally from the audio and log data. Human coders used richer data (several video streams) and a thorough understand of the tasks to code episodes as
collaborative, cooperative or asymmetric contribution. Machine learning was used to induce a detector, based on random forests, that outputs one of these three codes for an episode given only a characterization of the episode in terms of superficial features. An overall accuracy of 92.00% (kappa = 0.82) was obtained when
comparing the detector's codes to the humans' codes. However, due irregularities in running the study (e.g., the tablet software kept crashing), these results should be viewed as preliminary.

Description
The quality of user interface designs largely depends on the aptitude of the designer. The ability to generate mental abstract models and characterize a target user audience helps greatly when conceiving a design. The dry cleaning point-of-sale industry lacks quality user interface designs. These impaired interfaces were compared with textbook design techniques to discover how applicable published interface design concepts are in practice. Four variations of a software package were deployed to end users. Each variation contained different design techniques. Surveyed users responded positively to interface design practices that were consistent and easy to learn. This followed textbook expectations. Users however responded poorly to customization options, an important feature according to textbook material. The study made conservative changes to the four interface variations provided to end-users. A more liberal approach may have yielded additional results.

Description
Cyber threats are growing in number and sophistication making it important to continually study and improve all dimensions of digital forensics. Teamwork in forensic analysis has been overlooked in systems even though forensics relies on collaboration. Forensic analysis lacks a system that is flexible and available on different electronic devices which are being used and incorporated into everyday life. For instance, cellphones or tablets that are easy to bring on-the-go to sites where the first steps of forensic analysis is done. Due to the present day conversion to online accessibility, most electronic devices connect to the internet. Squeegee is a proof of concept that forensic analysis can be done on the web. The forensic analysis expansion to the web opens many doors to collaboration and accessibility.

Description
As part of the InnovationSpace program, interdisciplinary teams of five undergraduate students from the areas of business, engineering, graphic design, industrial design, and sustainability are responsible for creating a product idea that addresses a societal need. My team, Flo, was tasked with finding a product/service solution that will increase collaboration or creativity in a workplace environment. After deciding as a group how to define collaboration—working with others to achieve a common goal—and creativity—getting to an end goal in a different way than is expected—we spent the fall 2014 semester researching pain points and areas of interest for potential customers and users. We learned that one of the barriers to productivity for our target users in startups and mature corporations is that they often lack the right mix of private and collaborative spaces. From this insight, we created a product system called Trenz.
There are benefits and drawbacks to both collaboration and individual work. Trenz sits at the intersection of both work styles, thus aiming to negate the downsides of both and harness their benefits based on real-time user needs. Holistically, the corporate workplace furniture industry is stagnant, despite several trends that pave the way for future innovation. Even though studies are consistently released on the benefits of natural light, flexibility, and activity in the workplace, the furniture industry has not yet responded with a solution that successfully solves all three while keeping the user in mind. As such, Trenz is a product-service system with the potential to create a new segment in the market because of its user-centric design, the support of individual/group work dynamics, and its feature set that can accommodate a diverse group of users.

Description
Research in the last decade has indicated that collaboration between speech-language pathologists (SLP) and general education teachers is a necessary component for effective instruction. Students that have language difficulties should have the necessary support to help them succeed in the general education classroom. Despite the overwhelming evidence that supports that collaboration is the best practice, it does not take place due to lack of training, time, and funding. My creative project includes a template and website that allows SLPs and teachers to collaborate to enrich instruction targeted towards third grade students diagnosed with a language disorder. This template is designed for the SLP to contribute specific language-based strategies that they implement during their therapy sessions. In turn, the general educator can access the template and easily integrate those strategies into her lessons to support the language skills of her students so that the student has more opportunities to generalize their skills. The template is formatted around the IEP goals of the students and aligned to the Common Core standards. The purpose of the template is to provide SLPs and general education teachers a means to collaborate without having to take additional time from each other's limited schedules and eliminates the need for in-person training to implement these strategies to effectively support students with language disabilities struggling in the general education classroom.

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.

Description
Course-Based Undergraduate Research Experiences, or CUREs have become an increasingly popular way to integrate research opportunities into the undergraduate biology curriculum. Unlike traditional cookbook labs which provide students with a set experimental design and known outcome, CUREs offer students the opportunity to participate in novel and interesting research that is of interest to the greater biology community. While CUREs have been championed as a way to provide more students with the opportunity to experience, it is unclear whether students benefit differently from participating in different CURE with different structural elements. In this study we focused in on one proposed element of a CURE, collaboration, to determine whether student's perception of this concept change over the course of a CURE and whether it differs among students enrolled in different CUREs. We analyzed pre and post open-ended surveys asking the question "Why might collaboration be important in science?" in two CUREs with different structures of collaboration. We also compared CURE student responses to the responses of senior honors thesis students who had been conducting authentic research. Five themes emerged in response to students' conceptions of collaboration. Comparing two CURE courses, we found that students' conceptions of collaboration were varied within each individual CURE, as well as what students were leaving with compared to the other CURE course. Looking at how student responses compared between 5 different themes, including "Different Perspectives", "Validate/Verify Results", "Compare Results", "Requires Different Expertise", and "Compare results", students appeared to be thinking about collaboration in distinct different ways by lack of continuity in the amount of students discussing each of these among the classes. In addition, we found that student responses in each of the CURE courses were not significantly different for any of the themes except "Different Expertise" compared to the graduating seniors. However, due to the small (n) that the graduating seniors group had, 22, compared to each of the CURE classes composing of 155 and 98 students, this comparison must be taken in a preliminary manner. Overall, students thought differently about collaboration between different CUREs. Still, a gap filling what it means to "collaborate", and whether the structures of CUREs are effective to portray collaboration are still necessary to fully elaborate on this paper's findings.

Description
As the shift to more innovative and open workspaces continues gaining popularity, millennial-heavy trends are now influencing businesses to create a more "Google-ly" and open atmosphere that caters to the needs of different personalities in a quirky, fun and innovative fashion. Millennials are becoming even more central as they begin to dominate the work force and replace more than 75 million older workers who are nearing, or are currently at, retirement age (Twenge et al., 2010). These Millennials have high expectations of their employers and will quickly leave their job if these needs are not being adequately met . One of those expectations is a push for creating spaces that optimize creativity and collaboration among employees. Team n o o d l e aims to address this problem by tackling the issue of underutilized conference rooms that dominate traditional business environments. Team n o o d l e is introducing a product that aims to eliminate the inefficiencies of traditional brainstorming sessions, such as time spent prepping, sticky-note usage and clean up. Otlet is a multi-functional conference table that doubles as a recreational gaming center. Otlet combines work and play by creating an open and engaging environment for sharing ideas. It serves to enhance creativity and collaboration among workers, and in the process may be a catalyst to transform the culture of that workplace. Academic research has begun to validate the importance of fun in the workplace. A number of studies have demonstrated that fun relates to employee attitudes and affective states, such as job satisfaction, organizational commitment, engagement, positive mood, and positive emotions . (Fluegge, 2008; Karl and Peluchette, 2006a, b; Karl et al., 2007, 2008; McDowell, 2004). Today, a business's online presence is everything. A 2013 poll by AT&T revealed that 67% of businesses are using their website to market to customers . Additionally, 66% of small businesses are maintaining or increasing their spend on digital marketing . The rise in popularity of digital marketing and the Internet is, for the first time, empowering small businesses to compete with businesses of all sizes. The ability to reach audiences across the world has evened out the playing field and leveraged small businesses to compete on a national and global level. Otlet's success will be dependent on an effective and innovative digital marketing strategy. With that being said, I recommend that team n o o d l e implement an initial digital marketing strategy for Otlet that includes a website, paid ad campaigns, a search engine optimization strategy, landing page development, and content marketing.

Description
I analyzed a non-profit's educational content website called SolarSPELL and proposed to redesign its interface. SolarSPELL is a solar-powered, offline site that can be accessed without wifi. It looks and behaves exactly like a real website. SolarSPELL is used by children and community members in developing countries across the world, including Africa and the Pacific Islands. The original site was not intuitive or easy to use, which deterred users with low technical literacy, lowering its effectiveness and defeating its purpose of providing educational materials to schools in the community, because users were less likely to use it to access educational content. The website was not responsive, meaning that it did not resize well to fit tablet and mobile devices. I redesigned the site's UX based on user feedback and expert advice to create wireframes that improved the site's layout and user flow to make it more intuitive. I pulled user comments from past surveys on the site and designed solutions to each of the user's complaints. I implemented a filter system and a universal search bar to improve the process of finding specific pieces of content. I designed prototypes using Adobe Illustrator to create the visual side of the interface. I designed my wireframes and prototypes with responsiveness in mind, creating versions for desktop, mobile and tablet. I also illustrated banners for the East Africa and Native American versions of the site, featuring landscape and wildlife from the respective regions. This interface redesign will be coded into a working site and distributed to communities around the world.

Description
Virtual Reality (hereafter VR) and Mixed Reality (hereafter MR) have opened a new line of applications and possibilities. Amidst a vast network of potential applications, little research has been done to provide real time collaboration capability between users of VR and MR. The idea of this thesis study is to develop and test a real time collaboration system between VR and MR. The system works similar to a Google document where two or more users can see what others are doing i.e. writing, modifying, viewing, etc. Similarly, the system developed during this study will enable users in VR and MR to collaborate in real time.
The study of developing a real-time cross-platform collaboration system between VR and MR takes into consideration a scenario in which multiple device users are connected to a multiplayer network where they are guided to perform various tasks concurrently.
Usability testing was conducted to evaluate participant perceptions of the system. Users were required to assemble a chair in alternating turns; thereafter users were required to fill a survey and give an audio interview. Results collected from the participants showed positive feedback towards using VR and MR for collaboration. However, there are several limitations with the current generation of devices that hinder mass adoption. Devices with better performance factors will lead to wider adoption.
