The inkjet printing machine was initially used on ceramic parts as a small device in designing and advertising offices limitedly. In recent years, this device has been applied professionally to create high-quality patterns in the industry. In this method, liquid ceramic ink is sprayed on the specified parts by piezoelectric nozzles and after drying and discharging, the organic matter is baked a...

By introducing of digital techniques, forensic document examiners has been encouraged to work with better accuracy in non-destructive ways. The aim of this study was to present a non-destructive, accessible, economic (affordable), user friendly, portable, useful and easy technique for specifying the order of crossing lines of ink stroke and printed text. The intersections of LaserJet and In...

We present techniques that allow sharing of standardized digital ink in a heterogeneous collaborative environment. We explore the use of W3C InkML (Digital Ink Markup Language) and show how it is more flexible and suitable than other digital ink formats for this purpose. We discuss different possible digital ink sharing schemes using InkML and describe pros and disadvantages of each. We present...

Annotations on digital documents have clear advantages over annotations on paper. They can be archived, shared, searched, and easily manipulated. Freeform digital ink annotations add the flexibility and natural expressiveness of pen and paper, but sacrifice some of the structure inherent to annotations created with mouse and keyboard. For instance, current ink annotation systems do not anchor t...

Pen computing devices provide a natural interface for annotating documents with freeform digital ink. However, digital ink annotations are usually larger and sloppier than real ink annotations on paper. We present DIZI, a focus+context interface that zooms up a region of the underlying document for inking. Users write in the zoomed region at a comfortable size for the device. When the zoom regi...

Handwriting is one of the most natural ways for a human to record knowledge. In recent years this type of human-computer interaction has received increasing attention due to the rapid evolution of digital ink hardware. This thesis contributes to the art of efficient recognition of handwriting and compact storage of digital ink. In the first part of the thesis, we focus on the development of alg...

Pen-based computing has and continues to become accepted and increasingly used. Hardware and software vendors have typically stored and represented digital ink using proprietary or restrictive ink formats, and have provided software development toolkits to access or manipulate ink for user development on their devices. The variety of digital ink formats and device-dependent software toolkits ha...

There have been recent improvements in document technologies like the standardization of object interfaces to access and manipulate the properties of web documents. There has also been significant progress in pen based computing for recognition of digital ink in desktops, tablets and handheld devices. These have necessitated a need for further research on annotation architectures for digital do...

Literature suggests that it is possible to design and implement pen-based computer interfaces that resemble the use of pen and paper. These interfaces appear to allow users freedom in expressing ideas and seem to be familiar and easy to use. Different ideas have been put forward concerning this type of interface, however despite the commonality of aims and problems faced, there does not appear ...

We examine the common hierarchical data structure of digital ink representations in two distinctive ink domainclasses. Digital boards (eBoard) can receive inputs for both archival and reactionary modes from freehand writings (or drawings) and gesture-commands, respectively, from the digital pens. The latter is modelled as a result of the former in theoretical pattern recognition, and perhaps, m...
