A number of applications are available that are designed to enhance student engagement in the classroom through the use of Tablet PCs. The value of this goal is well documented, and researchers working with applications such as Classroom Presenter and DyKnow Vision have blazed the way in studying not only how best to deploy this technology, but also how to best teach with it in actual classroom...

1. ABSTRACT We analyze the use of digital ink by three instructors of introductory university physics classes, discussing how they organize their slides, the ways in which they ink, and how they support their dynamic classroom activity with instructor notes – a part of the Presenter (UP [1] and CP [2]) framework. We find modes of usage including using ink to explicitly link multiple representat...

Recently, many pen-based devices have enabled people to input digital ink naturally. Often, there is smear and correction when writing. This not only makes the document dirty and look unpleasant, but also affects the handwriting recognition when recognition is called for. As the first paper to address the ink cleanup problem, we present our ink cleanup system that removes the smear and correcti...

The spencerlab DIGITAL COLOR LABORATORY has conducted cartridge reliability comparison testing of original HP Inc. [HP] inkjet cartridges, four (4) non-HP brands of Remanufactured ink cartridges, and four (4) non-HP brands of Refill retailers/Refill ink kits sold as substitutes in North America (NA). The study included testing of HP #61XL, #62XL, #63XL, #564XL, #950XL, #951XL, #970XL, and #971X...

A number of software tools are available to annotate documents with digital ink. However, they only partly solve the problem of annotating and grading student assignments, this task requires digital annotation capabilities, recognition of digital ink and support for workflow practices. We are particularly interested in marking student programming assignments. Programs differ from essays and rep...

The final print quality depends on the quality of the digital image as well as the properties of the printing system, the inks and the paper used. One of the most widely used digital printing technologies is ink jet, where ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most ink jet inks have low viscosity and low surface tension, which pose high deman...

Modelling freehand writing in all its capacitive expressiveness and stylised apotheosis is highlighted in this paper. We derive the necessary requirements for freehand writing representation from observations made in e-learning scenarios where the representation of ink data describing the dynamics of freehand writings as natural parameters is useful. We show that random real-time access for rec...

Despite the potential benefits of digital note taking tools, research has found that people continue to use paper for creating micronotes, informal personal notes such as reminders and to-dos. Design recommendations from formative studies suggest that “natural” input modalities such as voice and digital ink could help to overcome the drawbacks of text entry on phones and PDAs. We conducted an 1...
