This study aims to investigate the following three issues: whether consumers process numeric information with locational cues, which locations (horizontal vs vertical) are more influential in processing numbers and whether a number-location association is weakened or strengthened when a visual reference frame moves up or down.

A field study and a series of three lab experiments were conducted to examine the location effect of numeric information on the package façade on the perceived magnitude of a number.

The authors found that a number at the right was perceived as larger than one at the left only when the number is located at the bottom. Also, placing numeric information at the bottom rather than the top of a product package façade was more powerful in processing the numeric information, but this is true only when the visual frame is set lower.

This study provides practical insights for product managers in placing core numeric information on product packaging to effectively communicate product value to consumers. Optimal locations can be deliberately considered along with types of numeric information and product categories. For healthy products that promote fewer calories, the top area of the package façade may be a better position for placing information on calories per serving to make the product more appealing to those who follow a healthy diet. Heavier, more voluminous products (e.g., refrigerator) better position their volume/weight information at the bottom than at the top or at the right of the bottom than at the left of the bottom on the product facade. Either the left side or right side of the top position may be beneficial for thinner, lightweight products (e.g., television).

The present work adds valuable empirical findings; inconsistent with past research, left-right location-number associations are not always true. People tend to associate smaller numbers with left-side locations and larger numbers with right-side locations only when the number is located at the bottom. Also, the study reported that top-small, bottom-large associations are not always true. The difference in perceived magnitude of the number between a number at the top and one at the bottom within the visual frame is significant only when the visual frame is set close to the ground.

The increasing number of context aware services, which depend on various multimodal sensing, processing and actuating techniques, technologies and formats ask for a physical framework that is able to handle their heterogeneity. Thereto, we propose a context model bridging the semantic gaps between context aware services. In addition we propose a simple system architecture of Distribution Servers and Transformation Servers that bridge semantic gaps among context aware services. Applying our framework we solve the heterogeneity problem existing for location services. Location is typically a form of context where heterogeneity is a problem.

This work shows the evolution regarding regulation of location services in both the USA and the EU. The article explains why these services were first regulated and the regulation itself is then explained. Two of the most important issues regarding location information are privacy protection and unsolicited communications. Shown here is the huge commercial value of location information and how the user’s approval can be manipulated to obtain consent to process and use as much information as possible.

In the vision of pervasive computing, numerous heterogeneous devices, various information services, and users performing daily activities are physically co‐located in a environment. How can we coordinate the services and devices to assist a particular user in receiving a particular service so as to maximize the user’s satisfaction? To solve this human‐centered coordination issue, we propose an agent‐based service coordination framework for pervasive computing. It is called location‐aware middle agent framework. The middle agent takes account of the user location in cognitive way (based on location‐ontology), and determines best‐matched services for the user. Based on this coordination framework, we have developed a multi‐agent architecture for pervasive computing, called CONSORTS (Coordination System of Real‐world Transaction Services). In this paper, we first outline some requirements of the human‐centered service coordination in pervasive computing. Secondly, we describe location‐aware middle agent framework to fill the requirements. Lastly, we outline CONSORTS, an prototype of location‐aware middle agent framework, and two applications of CONSORTS, location‐aware information assistance services in a museum and wireless‐LAN based location systems on FIPA agent Networks.

The efficient delivery of environmental information to wayfinders in complex environments is a challenge for information designers. Wayfinding tasks can be quite strenuous and frustrating in the visual absence of dedicated wayfinding information. This study aims to explore the behaviour regarding the use of wayfinding information by navigators in complex environments.

An experiment has been conducted in which participants have performed wayfinding tasks in a spatially complex university campus. The participants were instructed to use the think-aloud protocol during the experiment. The behaviour has been recorded using the head-mounted video recorder (GoPro), mobile phone screen (audio\video) recorder and interview. Twelve university students have been selected based on the equal level of spatial ability using the Santa Barbara Sense of Direction scale. Each participant performed three wayfinding tasks to locate the unknown locations inside the campus using a mobile wayfinding application and other information sources.

The results of this study demonstrated significant behavioural preferences in acquiring wayfinding information. Most of the participants synthesised the static and mobile wayfinding information sources, while some preferred only the static ones. Gender differences have also been found for planning and route finding. This study recommends the syntheses of static and mobile wayfinding information for designing an efficient institutional wayfinding system.

The sample size has been kept small because of the qualitative exploration of the wayfinding behaviour regarding the wayfinding information syntheses behaviour. The experiment findings can be further explored with larger data set and controlled behavioural metrics. This study can help understand the user requirements in facilities management for spatially complex institutional environments.

The current findings can be further used to develop a framework for wayfinding information designers to assist them in understanding the current practices and incorporate them for improving institutional wayfinding systems. The management of the offered facilities within an institution can be further improved to make the space more efficient by saving users’ time and efforts.

Information syntheses or symbiosis of environmental information with the beacon-based digital wayfinding system is a new concept. This study explores the potential of such information syntheses for enhancing the legibility of complex institutional environments.

The paper aims to resolve three major issues in location-based applications (LBA) known as heterogeneity, user privacy, and context-awareness by proposing an elastic and open design platform named OpenLS privacy-aware middleware (OPM) for LBA.

The paper analyzes relevant approaches ranging from both academia and mobile industry community and insists the importance of heterogeneity, user privacy, and context-awareness towards the development of LBA.

The paper proposes the OPM by design. As a result, the OPM consists of two main component named application middleware and location middleware, which are cooperatively functioned to achieve the above goals. In addition, the paper has given the implementation of the OPM as well as its experiments. It is noted that two privacy-preserving techniques at two different levels are integrated into the OPM, including Memorizing algorithm at the application level and Bob-tree at the database level. Last but not least, the paper shows further discussion about other problems and improvements that might be needed for the OPM.

Each issue has its sub problems that cause more influences to the OPM. Besides, each of the issues requires more investigations in depth in order to have better solutions in detail. Therefore, more overall experiments should be conducted to assure the OPM's scalability and effectiveness.

The paper hopefully promotes and speeds up the development of LBA when providing the OPM with suitable application programming interfaces and conforming the OpenLS standard.

This paper shows its originality towards location-based service (LBS) providers to develop their applications and proposes the OPM as a unified solution dealing with heterogeneity, user privacy, and context-awareness in the world of LBS.

The purpose of this paper is to implement an activity support system for volunteer fire corps using Web-GIS technology.

In this study, the authors implemented a volunteer fire corps activity support system comprising a dispatch request system, a water sources geographic information system, a fire-vehicle location confirmation system, a route history system and an integrated management system. They implemented this system as a Web application in consideration of responsive design assuming that it is used on mobile terminals.

To evaluate the effectiveness of the proposed system, the authors conducted a survey of 18 fire corps volunteers who were asked to evaluate the system for operability, relevance, functionality, usability and effectiveness.

In this research work, the authors implemented the volunteer fire corps activity support system using Web-GIS technology. The authors conducted a questionnaire survey of the volunteer fire corps activity support system, asking 18 fire corps volunteers to evaluate the system for operability, relevance, functionality, usability and effectiveness. The results of the survey indicate an overwhelming positive response to the volunteer fire corps activity support system for all five measures.

The purpose of this paper is to establish reciprocity among socio-location attributes while underlining the additional users’ privacy implications on social media (SM).

Digital identity theories, social software engineering theory and the Privacy Safeguard (PriS) methodology were considered while reviewing 32 papers for identifying users’ SM attributes. After proposing interrelations among socio-location attributes, the PriS method was used to match social aspects of privacy in designing case studies to illustrate the associations through potential users’ privacy implications.

Eighteen users’ SM attributes were collected and correlated to the Face, Frame, Activity, Time and Stage (FFrATS) 4 W (socio-location attributes), which provoke further privacy implications due to the notions of self-determination and self-disclosure on SM. The authors draw on the PriS methodology to address privacy’s multidimensionality while creating case studies to examine privacy issues arising due to socio-location attribute disclosure and users’ trajectories and normativity lines.

Supplementary case studies and research are needed to enable the design of a socio-spatially and privacy-aware designing methodology.

Designing proper methodologies and techniques to address users’ privacy implications deriving from socio-location attributes can provide designers with a technical solution to SM platforms.

Socio-location attribute disclosure constructs representative SM profiles; however, the revelation of attributes and their interrelations create additional privacy implications for SM users.

Deepening the understanding of disclosing socio-location attributes on SM while bridging the socio-technical gap will provide the necessary background for proposing technical solutions to protecting users’ privacy.

Social media platforms provide a source of information about events. However, this information may not be credible, and the distance between an information source and the event may impact on that credibility. Therefore, the purpose of this paper is to address an understanding of the relationship between sources, physical distance from that event and the impact on credibility in social media.

In this paper, the authors focus on the impact of location on the distribution of content sources (informativeness and source) for different events, and identify the semantic features of the sources and the content of different credibility levels.

The study found that source location impacts on the number of sources across different events. Location also impacts on the proportion of semantic features in social media content.

This study illustrated the influence of location on credibility in social media. The study provided an overview of the relationship between content types including semantic features, the source and event locations. However, the authors will include the findings of this study to build the credibility model in the future research.

The results of this study provide a new understanding of reasons behind the overestimation problem in current credibility models when applied to different domains: such models need to be trained on data from the same place of event, as that can make the model more stable.

This study investigates several events – including crisis, politics and entertainment – with steady methodology. This gives new insights about the distribution of sources, credibility and other information types within and outside the country of an event. Also, this study used the power of location to find alternative approaches to assess credibility in social media.

Touch‐screen kiosks are situated in a variety of locations to provide the public with ready access to health information. This paper examines their use, via the transactional logs, and makes comparisons between the types of organisation in which the kiosks are housed. Twenty‐one kiosks were selected and categorised into four groups – pharmacy, hospital, information centre and surgery. A small case study features a supermarket kiosk. Details of nearly 90,000 user sessions and 750,000 page views were used for the comparison. Comparisons between sites were made in terms of number of users, their age and gender, trends over time, the number of sessions conducted, page view time, session duration, pages viewed, site penetration, number of pages printed and health topics viewed. There were considerable differences between the kiosk locations. This early research provides the quantitative foundation for a fuller study of kiosk location and the differences in perceptions of the quality/authority of kiosk data.
