This paper presents two empirical investigations of future applications of mobile spatial interaction, i.e. the use of mobile phones as pointers to the real world. In situated interviews and a photo diary study, real-world objects of interest for referencing services were identified. Furthermore, envisioned services, their attractiveness and relevant usage situations were explored. The presented results of the study indicate that access to background information on buildings as well as spatially-related search and service access are highly attractive for future users, whereas spatially-related purchase, advertisement, gaming, and sharing is of less interest.
