[Poster] Utilizing contact-view as an augmented reality authoring method for printed document annotation

Abstract

In Augmented Reality (AR) the real world is enhanced by superimposed digital information commonly visualized through augmented annotations. The visualized data comes from many different data sources. One increasingly important source of data is user generated content. Unfortunately, AR tools that support user generated content are not common hence the majority of augmented data within AR applications is not generated utilizing AR technology. In this paper we discuss the main reasons for this and evaluate how the contact-view paradigm could enhance annotation authoring process within the class of tabletop size AR workspaces. This evaluation is based on a prototype that allows musicians to annotate a music score manuscript utilizing freehand drawing on top of device screen. Experimentation showed the potential of contact-view paradigm as an annotation authoring method that performs well in single and collaborative multi-user situations.

Adaptive user perspective rendering for Handheld Augmented Reality

“…They later extended their investigations to specifically study the use of surrounding visual context in a map navigation task [7] and to sketching applications [18]. Pucihar et al also proposed a specific variation of UPR, called contact-view, which allows pseudo transparent rendering of documents when a smartphone lies directly on the document [17,16], achieving similar effects compared to proprietary solutions using transparent displays [12,13].…”

The Hybrid Stylus: A Multi-Surface Active Stylus for Interacting with and Handwriting on Paper, Tabletop Display or Both

“…It is thus not surprising that numerous concepts to merge the richness of paper interactions with the flexibility of digital content have been proposed, developed and explored [10]. A common coupling involves displaying digital information and commands (buttons, knobs and sliders) above the paper [11][12][13][14], on [15][16][17], besides [3,18] or beneath the paper [19][20][21][22]. Digital content can be displayed by either projecting it on and around paper, or by showing it on a nearby display.…”
