Work-in-Progress–—Improve Spatial Learning by Chunking Navigation Instructions in Mixed Reality

Although navigation system allows users reach destination easily, spatial learning is always necessary, especially in emergency situations. Intentional spatial learning is effective but always requires more attention. In this work-in-progress, we explore ways to improve incidental spatial learning with mixed reality-based (MR) navigation. We analyze how people structure space from volunteered geographic information (VGI) verbal navigation instructions, chunk the space accordingly and use different visual instructions among chunks in MR user interface. A user study is to be conducted to test if spatial learning is improved such design. The findings contribute to the design principles of MR-based navigation.
