As Japan has increasingly becoming a so-called “super-aging society,” and the number of people with mobility impairment has increased, the barrier-free improvements have been implemented to public facilities so far. After the New Barrier-free Law has been enforced, however, the conceptual basis of such improvements has been shifting toward the universal design, based on the idea that everybody should be able to use facilities impartially. This study clarifies the present situation and problems of the barrier-free improvements from a passenger ship terminal to the inside of a ship, and elucidates improvement issues of nodal points of future marine and land transport. We carried out a questionnaire and site survey for the Hiroshima Port Ujina Passenger Boat Terminal, as well as the ships used, where the improvements are made based on the New Barrier-free Law.

Point Detection

The interaction of hand tools with the user is crucial and a key factor for his or her performance. In specific medical devices like surgical instruments, it is also important to ensure patient safety, namely, to avoid the risk of a surgical instrument’s being left inside a body. This article investigates the patterns of hand-to-product contact areas by identifying the potential locations to couple an external add-on tracing device on surgical instruments. A user evaluation study was conducted to determine the contact areas between the surgeons’ hands and different surgical instruments. The methodology, the results, and a discussion are described below.

Reading Assignment

This study explores if peripheral colored ambient light or colored light can be noticed and semantically associated with text while reading a novel from an Electronic Visual Display (EVD). Additionally, it is investigated if those colored signs are perceived as supplementary to the story and result in a more immersive experience. For that purpose, a user evaluation study was performed based on attention theory (selective attention, semantic priming, and divided attention), reading behavior, and semantics of colors. Participants received a reading assignment. While reading a novel from an e-book, dynamic colored ambient light or colored light was emitted. Throughout the reading assignment, the colors were adapted to the particular scenes the participant was reading. Findings suggest that attention can be divided between reading the novel from an EVD and the ambient color signs.

Ubiquitous Computing Environments

AbstractUbiquitous computing environments advocate creating applications by plugging together various resources (mobile devices, displays, augmented everyday objects, and so on) and Web Services to support the user’s everyday activities and needs. This approach is referred to as application composition, and such applications are called composite. Due to the dynamic nature of ubiquitous environments, application composition has to be supported at runtime, so that the applications are able to adapt to the situation within the environment and other contexts. Application composition is usually performed by autonomous context-aware mechanisms that provide limited or no control for users. Still, users need to be aware of their environments and be able to control and configure applications when they are composed and executed. Towards this goal we present in this article a context-aware application composition system based on the iCompose interface for composing and controlling applications at runtime. Users compose applications by simply touching the resources in the environment with their mobile devices, while the iCompose interface provides feedback and assists users by suggesting them possible further actions. The interface relies on a rule-based reasoner and utilizes various context sources to support users dynamically, according to the situation in which they compose applications. We present a complete implementation of the system and report the results of a user evaluation study conducted with 21 participants. This study assesses the issues of control, usability, feasibility and user acceptance of the iCompose interface for context-aware application composition and the prototype as a whole.

Purpose Although many interventional approaches have been proposed to address the apparent gap between novices and experts for literature review (LR) search tasks, there have been very few approaches proposed for manuscript preparation (MP) related tasks. The purpose of this paper is to describe a task and an incumbent technique for shortlisting important and unique papers from the reading list (RL) of researchers, meant for citation in a manuscript. Design/methodology/approach A user evaluation study was conducted on the prototype system which was built for supporting the shortlisting papers (SP) task along with two other LR search tasks. A total of 119 researchers who had experience in authoring research papers participated in this study. An online questionnaire was provided to the participants for evaluating the task. Both quantitative and qualitative analyses were performed on the collected evaluation data. Findings Graduate research students prefer this task more than research and academic staff. The evaluation measures relevance, usefulness and certainty were identified as predictors for the output quality measure “good list”. The shortlisting feature and information cues were the preferred aspects while limited data set and rote steps in the study were ascertained as critical aspects from the qualitative feedback of the participants. Originality/value Findings point out that researchers are clearly interested in this novel task of SP from the final RL prepared during LR. This has implications for digital library, academic databases and reference management software where this task can be included to benefit researchers at the manuscript preparatory stage of the research lifecycle.

Purpose During the literature review phase, the task of finding similar research papers can be a difficult proposition for researchers due to the procedural complexity of the task. Current systems and approaches help in finding similar papers for a given paper, even though researchers tend to additionally search using a set of papers. This paper aims to focus on conceptualizing and developing recommendation techniques for key literature review and manuscript preparatory tasks that are interconnected. In this paper, the user evaluation results of the task where seed basket-based discovery of papers is performed are presented. Design/methodology/approach A user evaluation study was conducted on a corpus of papers extracted from the ACM Digital Library. Participants in the study included 121 researchers who had experience in authoring research papers. Participants, split into students and staff groups, had to select one of the provided 43 topics and run the tasks offered by the developed assistive system. A questionnaire was provided at the end of each task for evaluating the task performance. Findings The results show that the student group evaluated the task more favourably than the staff group, even though the difference was statistically significant for only 5 of the 16 measures. The measures topical relevance, interdisciplinarity, familiarity and usefulness were found to be significant predictors for user satisfaction in this task. A majority of the participants, who explicitly stated the need for assistance in finding similar papers, were satisfied with the recommended papers in the study. Originality/value The current research helps in bridging the gap between novices and experts in terms of literature review skills. The hybrid recommendation technique evaluated in this study highlights the effectiveness of combining the results of different approaches in finding similar papers.

Transfer Method

Style transfer is the process of rendering one image with some content in the style of another image, representing the style. Recent studies of Liu et al. (2017) show that traditional style transfer methods of Gatys et al. (2016) and Johnson et al.(2016) fail to reproduce the depth of the content image, which is critical for human perception. They suggest to preserve the depth map by additional regularizer in the optimized loss function, forcing preservation of the depth map. However these traditional methods are either computationally inefficient or require training a separate neural network for each style. AdaIN method of Huang et al. (2017) allows efficient transferring of arbitrary style without training a separate model but is not able to reproduce the depth map of the content image. We propose an extension to this method, allowing depth map preservation by applying variable stylization strength. Qualitative analysis and results of user evaluation study indicate that the proposed method provides better stylizations, compared to the original AdaIN style transfer method.

Purpose – The aim of the research is to realize a better form of personal identification number (PIN) authentication for a mobile phone without lowering usability and acceptability. Design/methodology/approach – The authors’ approach is to extend the input operation of PIN authentication by allowing more than one number at a time using a multi-touch-enabled screen. The authors also introduced substitution keys to be able to type any combination of a PIN value and an input pattern by multi-touch typing. Findings – The authors conducted a user evaluation study using a Web-based prototype system. The results of the study indicate that PIN input time, input errors and secret memorability of the proposed scheme were no worse than those of conventional PIN authentication. The theoretical security level of the proposed scheme is almost three and a half times than that of the conventional scheme. Originality/value – The paper introduced a multi-touch-allowed secret input operation into a PIN authentication. Though the introduction affected not only an input operation but also a PIN input interface and secret information, it makes possible to realize a better security level without a drastic change of a user interface and taking a longer input time.
