This chapter investigates the research projects and prototypes related to currently available mobile applications used in wayfinding and navigation. The advancement in small-screen devices, mobile computing and modelling counterpart, location awareness techniques, and wireless technologies have improved screen resolutions and provided technical solutions for delivering textual, 2D, and 3D information to a mobile device. After investigating small-screen representations and the related navigation content and mobile interface design from the previous cases, two suggestions are presented in this chapter in order to enhance the design for future mobile wayfinding systems: 1) pseudo-3D representations and 2) personalised and on-demand services.

The Impact

We propose a mobility-assisted on-demand routing algorithm for mobile ad hoc networks in the presence of location errors. Location awareness enables mobile nodes to predict their mobility and enhances routing performance by estimating link duration and selecting reliable routes. However, measured locations intrinsically include errors in measurement. Such errors degrade mobility prediction and have been ignored in previous work. To mitigate the impact of location errors on routing, we propose an on-demand routing algorithm taking into account location errors. To that end, we adopt the Kalman filter to estimate accurate locations and consider route confidence in discovering routes. Via simulations, we compare our algorithm and previous algorithms in various environments. Our proposed mobility prediction is robust to the location errors.

Abstract. Landslides occur frequently all over the world, causing at times considerable economic damage, injuries and even death. In order to improve hazard assessment, common landslide types of a given region need to be investigated in detail. While traditional techniques of subsurface investigation are expensive and only provide point information, geophysical methods are suitable tools for gathering 2D and 3D information on the subsurface quickly, reliably and cost-effectively. In this study, the suitability and limitations of 2D resistivity for the determination of landslide extent, structure and soil moisture conditions are presented. For this purpose, two identical profiles were taken during a two-month period. Significant differences in electrical resistivity (>1000 Ωm) due to varying soil moisture conditions were observed. Using various inversion parameters, it was possible to model two distinct subsurface images. Regrettably, the sliding plane could not be detected reliably, possibly due to the homogeniety of the landslide material and underlying bedrock.

There is a noticeable gap in academic studies between comic books and hypermedia. On the one hand, are found several publications on both printed and digital comic books. On the other hand, are publications aimed at media and technologies for content usability for small screen devices. Therefore, this study focuses on the development of comic books for small screen device reading. A parameter guide for the so-called Webtoons was developed, based on theoretical foundation, observation of webcomics in this style on content platforms, and 3 phases of qualitative field research. The research included interviews with comic artists, comic book professionals, and, seeking successive refinement, the guide's presentation to students as educational material.

Abstract In this paper, Confocal Chromatic Microscopy was investigated to characterize the micro-bump fabrication process. We designed and fabricated in house a new detector that integrates through the same optical chromatic lens two light beams that are reflected into a 2D line scan camera and a spectrometer to obtain on the fly 2D and 3D information while scanning the wafer surface. We inspected 300 mm round wafers hosting arrays of copper micro-bumps down to 10 μm in width and 5 μm in height at post Cu growing and etching step. The 2D inspection revealed the presence of partial μbumps, shifted and missing μbumps. The 3D inspection could recognize shorter and taller bumps and determine the coplanarity of each bump population at die level. This information could be used to classify GOOD and BAD dies over the wafer, so that after dicing only known good dies would be used in the following advanced packaging step. In this way, the risk of shorts and / or missing contact is minimized when stacking dies either on a wafer or on a die.
