Über dieses Buch

This book investigates the functional adequacy as well as the affective impression made by feedback messages on mobile devices. It presents an easily adoptable experimental setup to examine context effects on various feedback messages and applies it to auditory, tactile and auditory-tactile feedback messages. This approach provides insights into the relationship between the affective impression and functional applicability of these messages as well as an understanding of the influence of unimodal components on the perception of multimodal feedback messages. The developed paradigm can also be extended to investigate other aspects of context and used to investigate feedback messages in modalities other than those presented. The book uses questionnaires implemented on a Smartphone, which can easily be adopted for field studies to broaden the scope even wider. Finally, the book offers guidelines for the design of system feedback.

Frontmatter

Chapter 1. Introduction and Motivation

Abstract
In their daily lives, many people carry small but powerful computers in their pockets: modern smartphones.
Julia Seebode

Chapter 2. Assessing the Quality and Usability of Multimodal Systems

Abstract
To develop a user-friendly system, it is necessary considering quality aspects as early as possible in development process.
Julia Seebode

Chapter 3. System Feedback on Mobile Devices

Abstract
The partial reversion of the effects of a process to its source or to a preceding stage

Chapter 4. Experimental Paradigm to Examine the Affective Quality and Functional Connotation of Feedback in Different Contexts

Abstract
So far, no standardized methods have been developed to study the influence of context on feedback perception. Therefore, one aim of this thesis is to provide an easy to realize and possibly realistic setup to investigate the influence of context aspects.

Chapter 5. Affective Quality and Functional Connotation of Auditory Feedback

Abstract
This chapter will present a series of studies to investigate the relationship between functional applicability and affective impression of earcons and auditory icons (see Sect. 3.​2).
Julia Seebode

Chapter 6. Affective Quality and Functional Connotation of Tactile Feedback

Abstract
This chapter describes a series of two studies: a Pilot Study to find meaningful vibrotactile messages of which then the affective impression and functional connotation is investigated using a smartphone, as in the previous chapter within varying staged contexts.
Julia Seebode

Chapter 7. Affective Quality and Functional Connotation of Auditory-Tactile Feedback

Abstract
So far, the investigated audio and tactile feedback messages under examination were tested unimodally. However, the combination of sound and vibration gives the possibility of audio-tactile feedback which could overcome the special disadvantages of each singe feedback modality.
Julia Seebode

Chapter 8. Investigating Different Types of Feedback in a Mobile Interaction Paradigm

Abstract
So far, the empirical work in this thesis focused on the sole perception of feedback messages without real interaction. As a next step to understand the influence of feedback in a mobile situation, an Interaction Study, which constitutes the concluding empirical part of this work, is described in this chapter.
Julia Seebode

Chapter 9. Conclusion and Future Work

Abstract
This concluding chapter summarizes the findings of the empirical part of this work, followed by guidelines derived after the study results.
