Tracking errors severely impact the effectiveness of augmented reality display techniques for indoor navigation. In this work we take a look at the sources of error and accuracy of existing tracking technologies. We derive important design criteria for robust display techniques and present objective criteria. These serve evaluation of indoor navigation techniques without or in preparation of quantitative user studies. Based on these criteria we propose a new error tolerant display technique called Bending Words, where words move along the navigation path guiding the user. Bending Words outranks the other evaluated display techniques in many of the tested criteria and provides a robust, error-tolerant alternative to established augmented reality indoor navigation display techniques.

During the past years, the development of assistive technologies for visually impaired (VI)/blind people has helped address various challenges in their lives by providing services such as obstacle detection, indoor/outdoor navigation, scene description, text reading, facial recognition and so on. This systematic mapping review is mainly focused on the scene understanding aspect (e.g., object recognition and obstacle detection) of assistive solutions. It provides guidance for researchers in this field to understand the advances during the last four and a half years. This is because deep learning techniques together with computer vision have become more powerful and accurate than ever in tasks like object detection. These advancements can bring a radical change in the development of high-quality assistive technologies for VI/blind users. Additionally, an overview of the current challenges and a comparison between different solutions is provided to indicate the pros and cons of existing approaches.

“…This has the advantage of using existing portable devices, but is limited by providing only one point of contact. Recommendations for multimodal systems to support navigation include (Kuriakose et al, 2020) portability, easy addition of new features or modalities without overloading the user, flexible customisation options for user settings, multiple modalities including audio feedback and the ability to select the most appropriate mode of interaction for the current circumstances. Users may require training to familiarise themselves with new systems, such as virtual interfaces (Guerrón et al, 2020).…”

The results presented here were obtained from an experimental study of blind people's experiences on two routes with very different characteristics. They are intended to answer three research questions on how blind people identify environmental features while travelling and use environmental information to form spatial representations, and the implications for the design of electronic travel aids to better support mental mapping of space. The results include detailed discussions of the mainly tactile and auditory information used by blind people to identify objects, as well as the different combinations of sensory information used in forming mental maps, the approaches participants used to do this, and the sensory modalities involved. They also provide a categorisation of the main features in participants’ descriptions of the two routes. The answers to the three questions include a discussion of the relationship between the sensory information used in route descriptions and mental maps, and the implications of the results for the design of electronic travel aids to support mental mapping, including suggestions for new types of aids and guidelines for aid design.
