“…A product with ease of use but no perceived usefulness would eventually be rejected by its potential users. In other words, perceived usefulness has a greater effect on BI than perceived ease of use does, which confirms the findings of previous studies by other researchers (Davis, 1989;Yang et al, 2011b).…”

AbstractPurpose -Tablets are becoming mainstream devices for digital reading. Through user experience (UX), the purpose of this paper is to identify significant differences between tablet reading systems and other digital reading systems, explore potential requirements for the interactive interface, and propose design solutions so that user' behavioral intention (BI) may be further enhanced. Design/methodology/approach -First, the authors extracted the context of use and behavior patterns by conducting contextual inquiries; then, potential requirements were identified and design solutions were developed; last, the technology acceptance model was employed to verify research findings. Findings -The outcome shows that the improved version of the interactive interface is significantly ( po0.05) superior to the original version in various aspects, including perceived usefulness, perceived ease of use, user attitude, and BI. Originality/value -So far, there has been no relevant research on UX concerning tablet reading systems. Therefore, this study first tried to investigate the primary difference between tablet reading systems and other digital reading systems in context of use and behavior patterns. Then, based on the foregoing discoveries, users' motivations and perception of tablet readers were probed, and the problems with BI could be solved.

“…The reason for adopting TAM is that TAM is a mature model and it effectively and accurately interprets the usability of technology products and users' attitude (ATUT) and behaviour intention (BI) towards technology products Maher 2008, Pan andJordan-Marsh 2010). Furthermore, TAM is more appropriate for measuring the overall user experience than usability is (Yang et al 2011). Furthermore, TAM is more appropriate for measuring the overall user experience than usability is (Yang et al 2011).…”

This study employs an interface design on a Tablet to facilitate in-depth reading for learners and allow them to apply better strategies and skills when reading; thereby cultivating their positive attitude towards reading and improving their willingness to use Tablets. Using human-centred design, we first investigated the Tablet functions within learner wants and needs based on their reading experiences, analysed each function and its correlation to reading satisfaction, and obtained a basis for evaluation. We next employed the 10 functions demonstrating the highest importance to complete a prototyping design. Finally, based on the technology acceptance model, we employed experimental methods to verify the prototype using the post-test-only control group design. The results of the study indicate that for perceived usefulness, perceived ease of use, reading and using attitudes, and behaviour intentions, the average scores for the improved Tablet were significantly higher (p < 0.05) than those for the original version.

“…After each task, participants completed a paper questionnaire -embossed in Braille -on navigation experience and cognitive effort. The 3 http://www.isbvik12.org/ questions were excerpted from the corresponding modules of the DEEP usability instrument [25]. At the end, a 10-minute interview gauged participants' experience with the navigation pattern, open comments, and difficulties encountered.…”

Navigating back and forth from a list of links (index) to its target pages is common on the web, but tethers screen-reader users to unnecessary cognitive and mechanical steps. This problem worsens when indexes lack information scent: cues that enable users to select a link with confidence during fact-finding. This paper investigates how blind users who navigate the web with screen-readers can bypass a scentless index with guided tours: a much simpler browsing pattern that linearly concatenates items of a collection. In a controlled study (N=11) at the Indiana School for the Blind and Visually Impaired (ISBVI), guided tours lowered user's cognitive effort and significantly decreased timeon-task and number of pages visited when compared to an index with poor information scent. Our findings suggest that designers can supplement indexes with guided tours to benefit screen-reader users in a variety of web navigation contexts.
