“…This also emphasises the importance of physical documents and interaction with them. Campos et al [9] showed how placing a tablet computer beneath the paper can be used to make static objects perceptually dynamic whilst Cook et al [13] revealed how integrating electronic circuits into paper can be used to illuminate various parts of an image in a book. IllumiPaper is another example of integrating electronics into paper where visual extension and interactivity is achieved using conductive ink and electroluminescence [38,39].…”

Despite the drive to digitise learning, paper still holds a prominent role within educational settings. While computational devices have several advantages over paper (e.g. changing and showing content based on user interaction and needs) their prolonged or incorrect usage can hinder educational achievements. In this paper, we combine the interactivity of computational devices with paper whilst reducing the usage of technology to the minimum. To this end, we developed and evaluated a novel back-print illumination paper display called LightMeUp where different information printed on the back side of the paper becomes visible when paper is placed on an interactive display and back-illuminated with a particular colour. To develop this novel display, we first built a display simulator that enables the simulation of various spectral characteristics of the elements used in the system (i.e. light sources such as tablet computers, paper types and printing inks). By using our simulator, we designed various use-case prototypes that demonstrate the capabilities and feasibility of the proposed system. With our simulator and use-cases presented, educators and educational content designers can easily design multi-stable interactive visuals by using readily available paper, printers and touch displays.

“…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.…”

The distinct properties and affordances of paper provide benefits that enabled paper to maintain an important role in the digital age. This is so much so, that some pen–paper interaction has been imitated in the digital world with touchscreens and stylus pens. Because digital medium also provides several advantages not available to physical paper, there is a clear benefit to merge the two mediums. Despite the plethora of concepts, prototypes and systems to digitise handwritten information on paper, these systems require specially prepared paper, complex setups and software, which can be used solely in combination with paper, and, most importantly, do not support the concurrent precise interaction with both mediums (paper and touchscreen) using one pen only. In this paper, we present the design, fabrication and evaluation of the Hybrid Stylus. The Hybrid Stylus is assembled with the infinity pencil tip (nib) made of graphite and a specially designed shielded tip holder that is attached to an active stylus. The stylus can be used for writing on a physical paper, while it still maintains all the features needed for tablet interaction. Moreover, the stylus also allows simultaneous digitisation of handwritten information on the paper when the paper is placed on the tablet screen. In order to evaluate the concept, we also add a user-friendly manual alignment of paper position on the underlying tablet computer The evaluation demonstrates that the system achieves almost perfect digitisation of strokes (98.6% of strokes were correctly registered with only 1.2% of ghost strokes) whilst maintaining excellent user experience of writing with a pencil on the paper.
