“…However, designers and researchers are often in a rush to create new installations and remediate previous media forms [4] and conceptual approaches for urban spaces. Such an approach is not necessarily sensitive to concerns of people, place, architecture or urban design, suggesting the need for new understandings of these designed objects, and the way they shape our experience of built and urban environments [30]. Mid-sized urban screens such as video walls and digital billboards are often just used as digital replacements for analog billboards.…”

Abstract-Weiser's seminal vision of ubiquitous computing had calm information presentation at its heart and identified an important challenge in providing pervasive yet unobtrusive information display while avoiding problems of information overload. Since this vision was first articulated, a range of approaches have emerged for presenting information on pervasive displays and digital screens of varying sizes are now an everyday feature of our environments. Such displays provide significant opportunities for presenting information in-situ to support users in a range of activities, and the growing expectation is that there is constant peripheral access to digital information. In this article we review three different pervasive display technologies used for information presentation: traditional 2D display media, urban media façades, and novel display hardware. Our survey identifies five emerging trends that cross all three technologies: an increasing focus on situatedness, a movement towards non-expert users, growing demand for accessible interaction, a potential for new applications of data, and a difficulty in balancing 'calm' computing against presentation of data at an appropriate granularity and complexity.

“…However, while these technologies offer exciting possibilities, they also present challenges. For example, LCDs have an impact on the natural beauty of green space due to their artificial appearance [3]. Projectors, on the other hand, are difficult to use in the bright conditions typically found in these spaces.…”

There are various proposals for employing grass materials as a green landscape-friendly display. However, it is difficult for current techniques to display smooth animations using 8-bit images and to adjust display resolution, similar to conventional displays. We present ProgrammableGrass, an artificial grass display with scalable resolution, capable of swiftly controlling grass color at 8-bit levels. This grass display can control grass colors linearly at the 8-bit level, similar to an LCD display, and can also display not only 8-bit-based images but also videos. This display enables pixel-by-pixel color transitions from yellow to green using fixed-length yellow and adjustable-length green grass. We designed a grass module that can be connected to other modules. Utilizing a proportional derivative control, the grass colors are manipulated to display animations at approximately 10 [fps]. Since the relationship between grass lengths and colors is nonlinear, we developed a calibration system for ProgrammableGrass. We revealed that this calibration system allows ProgrammableGrass to linearly control grass colors at 8-bit levels through experiments under multiple conditions. Lastly, we demonstrate ProgrammableGrass to show smooth animations with 8-bit grayscale images. Moreover, we show several application examples to illustrate the potential of ProgrammableGrass. With the advancement of this technology, users will be able to treat grass as a greenbased interactive display device.INDEX TERMS Grass display and interface, non-luminescent displays, programmable matter, shapechanging display

“…Researchers and practitioners within the field have provided some insights into the body of knowledge of these new urban elements, from technology and prototyping [18], policy and design issues [19,20], social interaction [21], displayed context [22], to design challenges [23], aesthetics [24], and more. Alas, there is still very little research on the environmental and health impacts of outdoor media architecture [25].…”

Urban environments have become significantly brighter and more illuminated, and cities now consider media architecture and non-static, self-luminous LED displays an essential element of their strategy to attract residents, visitors, and tourists in the hours after dark. Unfortunately, most often, they are not designed with care, consideration, and awareness, nor do they support the visual wellbeing and circadian rhythms of humans. They also increase light pollution which has an adverse effect on the environment. The aim of this study was to estimate the scale of the negative impact of 28 non-static, self-luminous LED shop window displays within a real-life city context along the main shopping street Banhofstrasse in Zurich, Switzerland. An experimental field measurement survey investigation was performed to identify visual luminance with commonly available tools such as a luminance meter and a digital reflex camera for luminance photography. Moreover, the most important global approaches to reduce light pollution were evaluated in the form of existing guidelines, technical standards, and laws, all of which should be considered when specifying illuminated digital advertisements. A literature review and survey results both confirmed the extent of the problem and highlighted, too, the need to better measure, apply, and manage this new technology. The authors’ proposal for improvements involve practical recommendations for the design and implementation of future projects which can positively guide and direct this growing trend.
