In the teleoperation of construction machinery, the work situation is usually determined from images shown on several screens. However, because images displayed on screens are flat, information presented is poor compared to information obtained with the naked eye, such as the view angle, resolution, and depth information. Focusing on information presentation during the teleoperation of construction machinery, this report investigates information presentation methods in mound-leveling work, grasping work, and drilling positioning conditions.

Communication is sharing and conveying information. In visual communication especially visual messages have to be formulated and interpreted. The interpretation is relative to a method of information presentation method which is human construction. This holds also in the case of visual languages. The notions of syntax and semantics for visual languages are not so well founded as they are for natural languages. Visual languages are both syntactically and semantically dense. The density is connected to the compositionality of the (pictorial) languages. In the paper Charles Sanders Peirce’s theory of signs will be used in characterizing visual languages. This allows us to relate visual languages to natural languages. The foundation of information presentation methods for visual languages is the logic of perception, but only if perception is understood as propositional perception. This allows us to understand better the relativity of information presentation methods, and hence to evaluate the cultural relativity of visual communication.

Wide Field Of View

The teleoperation of construction machinery has been introduced to mines and disaster sites. However, the work efficiency of teleoperations is lower than that of onboard operations owing to limitations in the viewing angle and insufficient depth information. To solve these problems and realize effective teleoperations, the Komatsu MIRAI Construction Equipment Cooperative Research Center is developing the next-generation teleoperation cockpit. In this study, we develop a display for teleoperations with a wide field-of-view, a portable projection screen, and a system that reproduces motion parallax, which is suitable for depth perception in the operating range of construction machinery.

This article examines the influence of static/interactive infographics on reflective/impulsive students’ academic achievement. The study sample consisted of 80 undergraduate students who were divided into two groups according to their cognitive style (reflective/impulsive). Each group was further divided into two sub-groups based on the type of infographics (static/interactive) to be evaluated. The findings showed that interactive infographics are more effective than static infographics in improving academic achievement. Reflective students outperformed impulsive students in terms of academic achievement, and there was a significant interaction between interactive infographics and reflective students. This study may serve as a guide for educators and designers of learning resources in selecting the most appropriate forms of technology conforming to students’ varying cognitive styles. Implications for practice or policy: The designers of e-learning environments must focus on the cognitive style of each learner. The design of those environments must take into account the diversity of information presentation methods to meet the various cognitive styles. Students' academic achievement can be improved by the use of interactive infographics due to their richness in material, multimedia approach, and interactivity that stimulate and communicate with learners’ senses and positively affect their acquisition of information.

Intelligent Multimedia

Intelligent multimedia systems (IMMS) assist users in choosing the information content, and to design the information presentation, that satisfies their needs and idiosyncrasies. Towards this target, IMMSs posses and utilize knowledge concerning the means and function (purpose) of a presentation. ‘Means’ denote communication techniques (information carriers and modalities), as well as information content and information characteristics. The ‘function of a pr esentation’ denotes the communicative purpose of the presentation, methods for achieving that purpose, as well as a user's goals and tasks.
