Today's digital signage systems typically show content that has been scheduled well in advance by their respective "owners", i.e., companies or individuals who paid for and/or operate the public display. However, with the shift to open display networks that can obtain content from many sources and the corresponding advances in interaction and sensing technologies, the scheduling requirements in this domain are set to change radically. For example, we envision that displays in our environment will soon be able to adapt to their surroundings and allow viewers to appropriate them by actively selecting and/or contributing content. Such levels of interactivity and context-awareness will require new approaches to content scheduling. In this paper we discuss the challenges faced in developing new forms of application and content scheduling for Open Pervasive Display Networks.

This paper reports on large-scale trials of Internet-based university-level distance teaching. The use of technology, and more specifically the Internet, has been an important advance for distance education. However, simply translating material from familiar media into electronic form is rarely productive—and is certainly inadequate for supported distance education, which aims to engage the student in a “community of learning.” The value Internet technology brings to distance education lies not in direct translation from other media but in transformation of support mechanisms to exploit its potential range. The paper addresses how instruction and support functions can be served and potentially enhanced by an Internet-based structure. It considers which changes in culture help to preserve or improve teaching quality while adapting to screen-based and often asynchronous interactions. It discusses our trials of mechanisms for interactions among students and tutors; assignment marking using an electronic marking tool; electronic assignment handling; synchronous and asynchronous Internet-based problem sessions; and automatic student registration. The paper summarizes qualitative and quantitative findings of an extensive evaluation involving several hundred students over three courses and considering learning, student experience, assignment marking, problem sessions, scalability, and integration into existing administrative structures. It highlights both costs and gains of using the Internet to transform the distance learning environment for those associated with it: students, tutors, administrators, and institutions.

In several cases, the spectral properties of objects change and depend on the viewing angle. Some example of this kind of samples can be found in the printing industry where special effect coatings are used to obtain some effects on the surface of the printed media. This effect can be an additional gloss and even an effect of a color change with the viewing angle (goniochromism). To be colorimetrically characterized these samples require multiangular reflectance measurements. In this paper we represent reflectance recovery results for these coated samples using regression models and RGB measurements from multiple camera capture angles. The estimations are performed using 3-dimensional and 9-dimensional RGB data. We evaluated the differences in estimation performance for the chosen three angles by using standard color and spectral metrics and compared the recovery with 3-dimensional and 9-dimensional RGB data.

A part of the case for corpus building is always that the corpus will have many users and uses. For that, it must be easy to use. A tool and web service that makes it easy is the Sketch Engine. It is commercial, but this can be advantageous: it means that the costs and maintenance of the service are taken care of. All parties stand to gain: the resource developers both have their resource showcased for no cost, and get to use the resource within the Sketch Engine themselves (often also at no cost). Other users benefit from the functions and features of the Sketch Engine. The tool already plays this role in relation to four historical corpora, three of which are briefly presented.
