Getting the Big Picture on Small Screens

Abstract

This chapter provides an overview of the key factors that influence the quality of experience (QoE) of mobile TV services. It compiles the current knowledge from empirical studies and recommendations on four key requirements for the uptake of mobile TV services: (1) handset usability and its acceptance by the user, (2) the technical performance and reliability of the service, (3) the usability of the mobile TV service (depending on the delivery of content), and (4) the satisfaction with the content. It illustrates a number of factors that contribute to these requirements ranging from the context of use to the size of the display and the displayed content. The chapter highlights the interdependencies between these factors during the delivery of content in mobile TV services to a heterogeneous set of low resolution devices.

User Experiences and Differences in Viewing Architectural Images with Various Interfaces

“…Many studies have concentrated on resolving specific issues related to visualization due to requests from users (Bellman, Schweda, & Varan, 2009). The visualization of advertisements on different types of screens is an example that has been extensively studied in the communication framework (Heppner, Benkofske, & Moritz, 2004;Knoche, McCarthy, & Sasse, 2005;Knoche & Sasse, 2008). As indicated, studies conducted for evaluating differences in the effectiveness of generic visual messages due to differences in the screen size and the image quality are currently a matter of great interest for modeling communication and improving empathy between users and messages.…”
