Effects of display media type, ambient lighting, viewing distance, viewing offset, object type, and object size on large-screen display legibility

Spot colors are widely used in the food packaging industry. We wish to add a watermark signal within a spot color that is readable by a Point Of Sale (POS) barcode scanner which typically has red illumination. Some spot colors such as blue, black and green reflect very little red light and are difficult to modulate with a watermark at low visibility to a human observer. The visibility measurements that have been made with the Digimarc watermark enables the selection of a complementary color to the base color which can be detected by a POS barcode scanner but is imperceptible at normal viewing distance.

The Subject

The advent of the Portable Antiquities Scheme (PAS) has added a great deal to our understanding of prehistoric metal artefacts in England and Wales, namely in expanding enormously the corpuses of objects previously thought to be quite scarce. One such artefact type is the miniature socketed 'votive' axe, most of which are found in Wiltshire and Hampshire. As a direct result of developing such recording initiatives, reporting of these artefacts as detector finds from the early 2000s onwards has virtually trebled the number originally published by Paul Robinson in his 1995 analysis. Through extensive data-collection, synthesising examples recorded via the PAS with those from published excavations, the broad aims of this paper (in brief) are as follows: firstly, produce a solid typology for these artefacts; secondly, investigate their spatial distribution across England and Wales. As a more indirect third aim, this paper also seeks to redress the imbalance of focus and academic study specifically applying to Hampshire finds of this object type, which despite producing a significant proportion of the currently known corpus have never been the subject of detailed analysis.

When designing a layout, the designer must be aware of fundamental principles so as to make the design structured and consistent. When planning layout, a designer cannot be random and must consider essential factors, such as the media type, the readers, the design elements and so on. Electronic media, like web pages and electronic books, is a newer media than the print media, and is different in several aspects. Yet, the basic principles of the design are still identical. A solid layout is a great tool in communicating messages visually.
