Thanks to Apple's beta preview of iOS 11.3 released last week, app developers are already experimenting with the ARKit capabilities that will be available to regular users this spring. The highlight of ARKit 1.5 is vertical surface detection. The first iteration of ARKit was limited to horizontal surface detection, which has placed constraints on what developers could do with regards to room scanning.
Vertical surface detection alone will be able to make things like posters, shelves, and other wall hangings in addition to floor-dwelling couches, chairs, and tables far more interactive. The feature could also come in handy in arts and culture as well, allowing patrons to see works of art beyond a museum's collection. Apple has added detection of irregularly-shaped surfaces as well. So now developers need not be limited by the whimsical designs of architects and furniture makers.
