Multi-touch technology, used in consumer products such as the iPad, enables users to register multiple points of contact at the same time; this enables a user to interact with a touch screen interface using several fingers on one hand, or even both hands. This affords interface designers the opportunity to define gestural interactions based on what is most natural for users and not on merely what can be recognised and processed by technology. In light of this, the research question that this study aimed to address was: what is the most intuitive user-defined gesture set for conducting an informational search on a multi-touch tablet web browser? In addressing this research question, the aim of this study was to create a user-defined gesture set for conducting an informational search on a multi-touch tablet web browser, based on gestures elicited from participants with little or no experience with touch screen devices. It was necessary to use these participants as users who are familiar with touch screen interfaces would draw upon the gestures they have learnt or used before, and would therefore be biased in the gestures they proposed. Inexperienced or naïve users would simply provide gestures that came naturally to them, providing a more accurate reflection of what a typical, unbiased user would do. A set of hypotheses, relating to the gestures that would be elicited from this participant group, were drawn up and investigated. These investigations yielded the following key findings: • The use of two-handed gestures should be limited. • If two-handed gestures are developed for a specific function, an alternative one-handed gesture should be made available. • It is not be advisable to create completely novel gestures for tablet web browsing that do not correspond to any of the ways in which desktop web browsing is performed. • Should novel gestures be developed for tablet web browsing, gestures that are desktop computing adaptations, including those that require menu access, should be made available as alternatives to users. • Tasks should be designed is such a way that they may be completed with a variety of gestures. • Complex tasks should be designed in such a way that they may be achieved through varying combinations of gestures. These findings may assist interface designers and developers in the gestures they design or developer for their applications. In addition to these findings, the study presents a coherent, user-defined gesture set that may be used in practice by designers or developers.

<p>Interactive media in public environments, such as touch screen kiosks, is a strongly growing toolfor offering service, information, advertising and entertainment.

The study revealed problems, solutions, needs, goals etc, related to the use of theterminal. The final result is a proposed human computer interaction (HCI) design patterncatalogue for in-store touch screen terminals, which helps prevent the observed problems.

Abstract By the advantage of technology innovation, the New Technology-Based Firms can not only win the competitive advantage but also make a great contribution to the national economic growth. (Rickne & Jacobsson,1996¡FAutio & Yli-Renko,1998¡FAcs,1999¡FFontes & Coombs,2001)¡C The technology of touch screens originated in military use, but it has been extensively applied to consumer, commercial, and public products. Among the touch screens, the capacitive touch screens are the best and the most expensive product. There used to be a single producer in the industry. But now, there is another company with the key manufacture technology and this company is also our study case. This study used the descriptive case-study method to analyze the strategic positioning of the New Technology-Based Firm in the industry. This study suggests the ¡§Focus Strategy¡¨ to be the strategic positioning of the new technology-based Firm in the capacitive touch screens industry, including the ¡§Cost Focus Strategy¡¨ for the cost advantage of customizing sizes and the ¡§Focus Differentiation Strategy¡¨ for the customization policy.

Gestural interfaces are user interfaces controlled by users’ gestures, such as taps, flicks and swipes, without the aid of a conventional pointing device, such as a mouse or a touchpad. The development of touch screen technology has resulted in an increasing number of inventive gestural interfaces. However, recent studies have shown that well-established interaction design principles are generally not followed, or even violated by gestural interfaces. As a result, severe usability issues start to surface: the absence of signifiers for operative gestures, the weakening of visual feedback, the inability to discover every possible actions in the interface, as well as the lack of consistency, all of which are undermining the user experience of these interfaces thus need to be addressed. Further analysis of existing gestural interfaces suggests that the sole dependence on gestural input makes interface design unnecessarily complicated, which in turn makes it challenging to establish a standard. Therefore, an approach to supplement gestures with user attention is proposed. By incorporating eye gaze as a new input modality into gestural interactions, this novel type of interfaces can interact with users in a more intelligent and natural way by collecting input that reflects the users’ interest and intention, which makes the interfaces attentive. To demonstrate the viability of this approach, a system was built to utilise eye-tracking techniques to detect visual attention of users and deliver input data to the applications on a mobile device. A paradigm for attentive gestural interfaces was introduced to provide insights into how such interfaces can be designed. A software prototype with attentive gestural interfaces was created according to the paradigm. It has been found in an experiment that the new type of interfaces helped users learn a new application faster, and modestly increased their accuracy when completing tasks. This provided evidence that attentive gestural interfaces can improve usability in terms of learnability and effectiveness This study is focused on interfaces of mobile devices whose major input mechanism is a touch screen, which are commonly seen and widely adopted. Despite the fact that eye-tracking capability is not generally available on these devices, this study demonstrates that it has great potential to facilitate interfaces that are both gestural and attentive, and it can enable new possibilities for future user interfaces. / published_or_final_version / Computer Science / Master / Master of Philosophy
