“…Meanwhile the system also captures helpers' instructions from their display and sends them back to the workers' side. HMD-and marker-based AR has been examined for automotive assembly, inspection, and repair [19]. Also within automotive assembly, guidelines for AR-based training were suggested [2].…”

Figure 1: Remote support for car drivers is typically offered as audio instructions only (left). This paper presents a mobile solutionincluding a sketch-and gesture-video-overlay (right). ABSTRACTUneven knowledge distribution is often an issue in remote support systems, creating the occasional need for additional information layers that extend beyond plain videoconference and shared workspaces. This paper introduces SEMarbeta, a remote support system designed for car drivers in need of help from an officebound professional expert. We introduce a design concept and its technical implementation using low-cost hardware and techniques inspired by augmented reality research. In this setup, the driver uses a portable Android tablet PC while the expert mechanic uses a stationary computer equipped with a video camera capturing his gestures and sketches. Hence, verbal instructions can be combined with supportive gestures and sketches added by the expert mechanic to the car's video display. To validate this concept, we carried out a user study involving two typical automotive repair tasks: checking engine oil and examining fuses. Based on these tasks and following a between-group (drivers and expert mechanics) design, we compared voice-only with additional sketch-and gesture-overlay on video screenshots measuring objective and perceived quality of help. Results indicate that sketch-and gesture-overlay can benefit remote car support in typical breakdown situations.

Environmental scanning is a milestone at the start of futures studies and strategic planning process. It must be done collectively and as participatory as possible to explore, create, and test both possible and desirable futures to capture opportunities of the futures images, trying to optimize it, and at the same time to avoid or reduce the risks of future threats. Internal analysis focuses on the strengths and weaknesses of an organization, while external analysis focuses on the threats and opportunities that may suddenly happen in the future. These two types of analysis provide an inventory of all variables / factors or events / drivers, internal and external that characterizes the system. But this is not enough for long-term strategic planning, the issue is not really planning, but rather the manner in which planning is executed. So advanced analysis should be done to study the direct and indirect relations among these trends, issues, variables / factors. As the vector of key variables is extracted with relations (influence, dependency) in mind, The impact of each of these key variables on each other must be taken into account relative to the system under study; CIA (Cross-Impact-Analysis) method is used to study such impacts. Future studies and forecasting methods need to benefit from this analysis to focus on the effects of these unprecedented future events. This paper introduces such work by integrating the results of strategic planning tools with futures studies methods and this could be essential for advanced analysis.
