Sentient artefacts are our everyday life objects augmented with various sensors for value added services. We have been exploiting these artefacts for perceiving user context and proving proactive context aware services while keeping their natural appearances and roles intact. From our observations of these artefacts we have identified two passive advantages besides their explicit value added functionalities. The first is a profile-based participation of the artefacts in the application scenarios thus making the artefacts generalized, independent of the applications and reusable in various scenarios. The second one is the role of the static artefacts in identifying the location of the mobile artefacts thus eliminating the requirement of any dedicated location infrastructure for proactive services. In this paper we have discussed these two issues with illustrations of our findings.
