Abstract

Purpose

Evacuation drills should be more realistic and interactive. Focusing on situational and audio-visual realities and scenario-based interactivity, the authors have developed a game-based evacuation drill (GBED) system that presents augmented reality (AR) materials on tablet computers. The paper's current research purpose is to improve visual reality (AR materials) in our GBED system.

Design/methodology/approach

The author's approach is to develop a new GBED system that superimposes digital objects [e.g. three-dimensional computer graphics (3DCG) elements] onto real-time vision using a marker-based AR library, a binocular opaque head-mounted display (HMD) and other current easily available technologies.

Findings

The findings from a trial experiment are that the new GBED system can improve visual reality and is appropriate for disaster education. However, a few problems remain for practical use.

Research limitations/implications

When using the GBED system, participants (i.e. HMD wearers) can suffer from 3D sickness and have difficulty in moving. These are important safety problems in HMD-based systems.

Social implications

The combination of AR and HMDs for GBEDs (i.e. integrating virtual and real worlds) will raise questions about its merits (pros and cons).

Originality/value

The originality of the research is the combination of AR and an HMD to a GBED, which has previously been realized primarily as simulation games in virtual worlds. The authors believe that our research has the potential to expand disaster education.

Abstract

Purpose

The paper aims to describe the changes in buyer-supplier relationships among Japanese companies at the early 2000s, focusing on two critical features; long-term relationships and information sharing. In particular, the paper investigates the relationship between benefits from information-sharing activities within buyer-supplier relationships and the stability of these relationships.

Design/methodology/approach

The paper develops a questionnaire based on prior research related to Japanese companies and undertakes a questionnaire survey of 353 Japanese manufacturing companies (which belong to the machinery, electrical/electronics, transportation equipment, and precision industries) in 2002.

Findings

Although Japanese companies have been considered to have close relationships with their partners, the paper finds only a small proportion of buyers were willing to share sensitive information with their suppliers and/or expected to continue long-term relationships with them. In addition, an examination of factors relating to buyers' performance shows that receiving benefits from inter-organizational information-sharing activities (attending suppliers' meetings, sending engineers to suppliers, and proposing cost saving ideas) could affect buyers' incentives to sustain long-term relationships with their suppliers.

Originality/value

The paper provides empirical evidence of the changing nature of the buyer-supplier relationship in Japanese manufacturing companies. Specifically, the main contribution of this research is to provide empirical evidence indicating that the benefit from buyer-supplier relationships has an effect on the governance structure of these relationships.
