Additive manufacture techniques using concentrated colloidal inks are a promising approach for creating three-dimensional (3D) calcium phosphates scaffolds for bone repair and regeneration. Among those, the direct-write assembly allows building scaffolds with precise size and geometry. In the present work, commercial β-TCP and HA were used to produce two types of colloidal ink. According to the...

We devised and tested two new visual guides to help users comprehend distorted sketched information in magnification lenses. Distortion techniques, such as fisheye lenses, have the advantage of magnifying information without occluding the surrounding content. However distorted information in the transition region requires extra mental workload to understand: this can lead to frustration and rej...

Sketch-based user interfaces provide a more direct and convenient way for interacting with computers, especially for performing graphical tasks. Most computer programs provide a mouse-and-palette based user interface for editing shapes which can be cumbersome to use. In order to draw a shape, a user must first select the desired shape from a menu or from a hierarchy of menus, and then make a se...

From the viewpoint of archaeology, it is necessary to preserve historical artifacts for posterity. Digital archiving is one of the most effective ways to sustain these ancient objects into the future. In this paper, we focus on archiving handwritten documents with ink brush painting on an absorbent paper. Appearances of the documents can be vary among observing environments as shown in Fig.1. S...

This study is in the form of digilog [1] that synthesizes analogue sentiment and digital technology, which reinterprets the Four Gracious Plants in modern context. Interactive Ink-and-Wash Painting Project aims to enable audience to communicate with the work through synesthesia by expressing the four paintings of the Four Gracious Plants in interactive art. “Digilog Bamboo”, which is a part of ...

Handwriting is one of the most natural ways for a human to record knowledge. Recently, this type of human-computer interaction has received increasing attention due to the rapid evolution of touch-based hardware and software. While hardware support for digital ink reached its maturity, algorithms for recognition of handwriting in certain domains, including mathematics, are lacking robustness. S...

This paper describes a method of retrieving handwritten text using directional features. Text search from handwritten digital ink employing character recognition technology has been developed. However, the character recognition based approach does not support languages which are not assumed. To address this problem, the proposed method was devised to hypothetically segment text into character s...

The motivation for this research is based on how artists mix and print colour by traditional means (painting and printmaking) and how these differ from colour picker tools, slider bars and methods developed for digital printing, and whether it is possible to incorporate both? Artists have been expert at mixing colour for centuries, yet although the artist and designer has access to a wide range...
