Indonesia is currently experiencing population expansion while housing availability is decreasing, particularly in big cities like Jakarta. This fact has occurred in many large urban areas where people live in vertical housing units such as flats (rumah susun), boarding houses, and so on. However, flats have restrictions, namely in terms of space, while types of furniture are needed in sufficient quantities as user facilities. As a result, technology is required to make it easier to map furniture needs in the dwelling so that residents can adapt to their needs. Augmented reality technology can optimize the mapping through digital visualization, allowing residents to envision their needs with digital prototypes. This research uses a qualitative literature review and a design thinking approach. The results of the data will subsequently be used to create a prototype workflow for the use of Augmented Reality that can be customized. It is expected to optimize limited areas in space without reducing the number of facilities needed while also considering ergonomics.
