A Tablet PC is a portable computing device which combines a regular notebook computer with a digitizing screen that interacts with a complementary electronic pen stylus. The pen allows the user to input data by writing on or by tapping the screen. Like a regular notebook computer, the user can also perform tasks using the mouse and keyboard. A Tablet PC gives the users all the features of a regular notebook computer along with the support to recognize, process, and store electronic/digital ink, enabling a user to make and save hand-written notes or data. In institutions of teaching and learning, instructors often use computer-based materials like web pages, PowerPoint® slides, etc., to explain subject matter. The ability to annotate on presentation information using the electronic stylus of a Tablet PC has attracted the attention of the academic community to use the Tablet PC as a potential tool for increasing the effectiveness of presentations in teaching and learning. Tablet PC-based applications such as OneNote®, WindowsJournal® and Classroom Presenter have been developed to enhance note-taking in classrooms based on the fact that a pen stylus is a more natural form of input device for making notes on the computer as compared to the regular keyboard and mouse. Although tools like OneNote®, WindowsJournal® enhanced the note-taking process on the Tablet PC, they lacked the ability to allow the user to directly annotate on the lecture content. Classroom Presenter provides the ability to integrate classroom notes and the presentation material by allowing the instructors and students to annotate over the lecture material. However, all the above tools lacked the ability to allow a user to take notes over the output window of an arbitrary application like Excel, an active simulator or a movies players output. The Tablet PC based tool, WriteOn, developed at Virginia Tech, addresses this drawback. WriteOn, when deployed on the Tablet PC in a classroom environment, allows the instructor to utilize electronic ink to annotate on top of any application window visible on the Tablet PC display screen, including those that play active content like a movie or simulation. WriteOn facilitates a user to annotate over a dynamic application window by activating its virtual transparency surface called the eVellum (electronic vellum). The user can view a movie or an active simulation running in the eVellum background because of its transparent color. The user can deactivate the eVellum to make it invisible by "piercing" it if he/she wishes to access the desktop or an application window under the vellum window. WriteOn provides the instructor with the ability to broadcast a composite of the dynamic lecture content and ink annotations to the students in real-time. The term dynamic lecture contents is meant to indicate that the content being annotated need not be static words on a background, but may also be window contents that are changing in time. Using WriteOn, the students can make their own notes by writing on the eVellum enabled on top of the lecture stream window without losing visibility of the lecture. The instructor/student can save the ink annotations along with base lecture material as a movie file. The ability of WriteOn to improve classroom presentation and student note-taking as shown by initial tests, were pedagogically very useful. However, in order to deploy WriteOn on large scale in classrooms as an active and effective teaching tool of choice, several aspects of the application had to be improved. One aspect of the application that needed improvement was the user interface. The primitive Graphical User Interface (GUI) of the WriteOn tool was not easily usable by instructors and students from non-computer science backgrounds. The second aspect needing improvement was the operational performance of the application in terms of its CPU resource utilization. The WriteOn tool has shown to have operational performance issues during the screen capture process. This research therefore aims to address improvements in the GUI to make it more user friendly and increase the operational performance to the point where the user does not notice degradation of a base lecture application. Incorporation of these improvements has led us to rename the application as WriteOn1.0. WriteOn1.0 implements a picture-based GUI that comprises of two forms: a main form that appears shortly after WriteOn1.0 starts and a toolbar. The WriteOn1.0 toolbar appears in the center of the top edge of the display as soon as the user initiates a task like a screen recording session, by clicking on the appropriate menu button on the main form. The toolbar provides the user, accessibility to perform all the desired activities like annotating, screen recording, presentation broadcast, and piercing of the eVellum by a single-click of the appropriate menu icon. Tool tips that appear when the user points the mouse over a picture icon on the toolbar, explain the task that shall be performed when he/she clicks on the underlying menu icon. WriteOn1.0 introduces a window-like resizable and movable eVellum called the scalable eVellum that it activates in the area of interest specified by the user. Unlike the first implementation of the eVellum which had a fixed location and spanned the entirety of the user's desktop window, the instructor/student define the dimensions of the scalable eVellum and can choose to re-dimension, relocate and pierce through it at any point of time during a session. WriteOn1.0 also introduces the transparent mode of operation wherein the instructor/student, without having to deactivate the scalable eVellum can access any underlying window by a right-click of the mouse on the eVellum surface while the ink annotations are intact on the foreground. WriteOn1.0 addresses the operational performance issues observed during a screen capture session in WriteOn by capturing the activities only in the area of interest of the user for recording and broadcasting. By combining this scheme with a with a lossless screen capture codec called the MSU screen capture codec that has a high-compression ratio and that is optimized for speed for data compression, WriteOn1.0 greatly improves the operational CPU performance of the tool. WriteOn1.0 employs various technologies to implement its features. The improvements to operational performance are implemented by using the MSU screen codec from Moscow State University's Graphics and Media Lab. Microsoft®'s Video for Windows Framework (VfW) and WindowsMedia Player API's are used to realize the module that records the screen activities to an AVI file while DirectShow of DirectX and ConferenceXP API's are used for streaming presentations over a network. WriteOn1.0, with its features like its scalable eVellum, good operational performance and picture-based GUI is aimed at potentially making it a teaching tool of choice across classrooms and changing the method of classroom instruction of courses involving dynamic content. / Master of Science

This thesis provides an introduction to an advance in technology-aided instruction. Most of the research in this area has focused on PowerPoint® based applications or white board-centered electronic ink applications with the capability of broadcasting slides, ink annotations and so forth, used for presentation or classroom lectures. But these tools lack the capability of annotating on any kind of applications with active content playing (a movie or a simulation, for instance) in the background. Additional useful, but currently unavailable functionality would include the capability of broadcasting the presentation information, which can further consist of lecture slides, ink annotations, video of the desktop screen activity, or any other application program that might be used to demonstrate a concept or illuminate an idea. Therefore, the current research attempts to provide these facilities with a new tool, WriteOn. WriteOn improves both the presentation of information and the interactivity in classroom instruction, because it gives the instructor the ability to ink annotate on any application by using a virtual transparency surface, called electronic vellum or simply eVellum, which in effect resides on top of all desktop window applications. The instructor can enable the vellum at any point during the lecture and write on it to draw diagrams, make notes, emphasize points, or otherwise elucidate the presentation content. The instructor can also pierce the eVellum in order to switch to different applications, modify an applications parameters or operating values, or otherwise manipulate an operating program as part of a classroom demonstration or discussion. These features allow the instructor to demonstrate the dynamic operation of any application, which is an improvement on a static PowerPoint display of a program's operation. With WriteOn, the instructor can save the ink annotations along with desktop screen activity over an interval of time as a movie file and later make this file available to students. Alternatively, the instructor can transmit to the students the presentation information along with ink annotations in real-time so that the students can make their own notes on top of information being produced by the instructor. Thus the tool can be used to enhance the interactive lecturing process and help students to develop good note-taking processes and habits. WriteOn is also capable of saving the voice of the instructor, provided there is an audio device attached to the instructor's Tablet PC. However, broadcasting the instructor's voice is not yet fully supported. The WriteOn tool was developed using Microsoft's technologies: Windows Media Encoder® and DirectShow of DirectX®, as well as Microsoft's ConferenceXP API to achieve streaming of the presentation information. The first chapter explains the need for computer tools used for effective teaching purposes. The second chapter presents the architectural and technical details of WriteOn. Chapter three describes the architecture of the WriteOn tool. Chapters four through six explain the major software components of the system and also give the pros and cons of the DirectShow and Windows Media Encoder technologies. The seventh chapter provides an explanation of the usage of the tool by instructors and students. The eighth chapter presents the experiences of the instructors and students using the WriteOn tool in the classroom and concludes with a discussion of future work in this area. The Appendix V provides a developers guide for those who might like to expand on this open source code. / Master of Science

<p>The 2020 pandemic emphasized the need for accessible and accurate point-of-care diagnostic tests. With the continued development of isothermal nucleic acid amplification tests, this can be achieved. A requirement of these tests includes heating and holding a specific temperature, in this case, 65C for 30 minutes, for amplification to occur. To achieve this, heaters often require external feedback to control the temperature; bringing up the device’s cost. Several self-regulating heaters have been made with materials having a positive thermal coefficient of resistance eliminating the need for complex circuitry. With this property, point-of-care diagnostic tests can be simplified and made more accessible. In this study, ink-based positive thermal coefficient of resistance heaters are developed and characterized using the scalable method of screen printing to achieve 65C and aid in the detection of SARS-CoV-2. Various curing methods and screen-printing parameters were evaluated to improve the stability and understanding of the reproducibility of the heaters. The longevity of the heaters was evaluated with oxidation studies and a COMSOL model was created to study the heat transfer within the device. Furthermore, the heaters were successfully implemented into a second-generation electronic point-of-care diagnostic device. Detection of SARS-CoV-2 using a self-regulating heater removes the need for complex circuitry, improving the accessibility of point-of-care tests with the potential to be expanded to a wide range of pathogen detection. </p>
