Our interactions with the world are multisensory in nature-the senses move us through spaces, mix with our memories and are constantly connected by our brains. Focused only on vision for a long time, the field of human computer interaction (HCI) started to meaningfully bring together all our senses in designing interactions for a variety of media....

Quality of Experience (QoE) is inextricably linked to the user experience of multimedia computing and, although QoE has been explored in relation to other types of multimedia devices, thus far its applicability to wearables has remained largely ignored. Given the proliferation of wearable devices and their growing use to augment and complement the...

Omnidirectional videos have become a leading multimedia format for Virtual Reality applications. While live 360° videos offer a unique immersive experience, streaming of omnidirectional content at high resolutions is not always feasible in bandwidth-limited networks. While in the case of flat videos, scaling to lower resolutions works well, 360° vi...

A consumer in Information Centric Network (ICN) generates an Interest packet by specifying the name of the required content. As the network emphasizes on content retrieval without much bothering about who serves it (a cache location or actual producer), every Content Router (CR) either provides the requested content back to the requester (if exists...
Article
Multisensorial books enrich a story with either traditional multimedia content or sensorial effects. The main idea is to increase children’s interest in reading by enhancing their QoE while reading. Studies on enriched and/or augmented e-books also propose synchronizing additional content with text. However, they usually focus on audio, vídeo, imag...

This chapter provides an overview of ICN. This also covers Internet architecture in its present form and its limitations. The chapter also covers Content Distribution Network (CDN) in b...
Chapter
Contents in ICN require universally location independent, unique, secure, and human-friendly identification. But it is a tough task to propose one single naming mechanism that fulfills all of these criteria. Instead of it, a multilayer/hierarchical naming mechanism that merges self-certifying identifiers with human-friendly keywords which is much p...
Chapter
Since the inception of ICN, there are many architectures proposed by various researchers. This chapter aims at describing all the available architectures proposed since 2009. The chapter starts with a brief description of the importance of ICN architecture and the need for a stable architecture for the wide acceptance of the new technology. The arc...
Chapter
Unlike an IP-based network, which is based on a host-centric approach, the ICN is based on content-centric approach. It implies that, for ICN, the location of the content is of greater importance than the producer of the content. Because ICN states that if a chunk of data is in the cache of a user and another neighbor is looking for the same chunk...
