Abstract
Blockchain technology brings new possibilities in assisted spatial navigation. Decentralized map building enables collaboration between users around the world, while providing researchers with a common reference map for extending the capabilities of navigational systems towards more intuitive and accurate landmark navigation assistance. Research on landmark navigation has been mainly focused on the visual characteristics of landmarks. Human behavior, however, has systematically been shown to be enhanced in the presence of multisensory unified events. We propose, therefore, the enhancement of spatial assisted navigation by utilizing landmarks that are multisensory and semantically congruent. Further, our research will provide insights in terms of the auditory parameters that could be combined with a given visual landmark, so as to facilitate landmark retrieval algorithms and user satisfaction during assisted spatial navigation.

Landmark assisted navigation The use of distance-to-turn verbal information (e.g., “in 55 metres turn left”) might be a widespread technique in spatial navigation systems, yet not the most reliable and easy to understand navigation method (May & Ross, 2006)
The load on the visual system and the multisensory events around us, it remains an open question how cues from other modalities that are relevant to a given visual landmark could further improve spatial navigation
To sum up, decentralized and consensus-driven map building from users around the world (OSM and FOAM-The consensus driven map of the world; Wright, 2018) offers a common reference point to navigation researchers and creates new opportunities in the design of http://epublishing.ekt.gr | e-Publisher: EKT | Downloaded at 05/10/2020 19:48:08 |
Summary
Landmark assisted navigation The use of distance-to-turn verbal information (e.g., “in 55 metres turn left”) might be a widespread technique in spatial navigation systems, yet not the most reliable and easy to understand navigation method (May & Ross, 2006). Research has shown that congruent audiovisual landmarks enhance wayfinding performance in maze environments by reducing the distance travelled and decreasing the time travelled (e.g., Werkhoven, van Erp, & Philippi, 2014). It seems that auditory stimulation enhances visually presented cues mostly when the two are somehow correlated (e.g., Ardito et al, 2007), it is not yet clear how the audiovisual landmarks would affect different aspects of navigation such as wayfinding and spatial memory navigation in a complex city environment. The effect of landmark modality on spatial navigation will be addressed by using, for the first time, a three-dimensional virtual city environment with realistic visually or audiovisually presented landmarks. If multisensory landmark presentation shows better navigation performance, OSM tags of landmarks should be modified so as to include a mix of visual and auditory information
