User experience (UX) research on pervasive technologies faces considerable challenges regarding today's mobile context-sensitive applications: evaluative field studies lack control, whereas lab studies miss the interaction with a dynamic context. This dilemma has inspired researchers to use virtual environments (VEs) to acquire control while offering the user a rich contextual experience. Although promising, these studies are mainly concerned with usability and the technical realization of their setup. Furthermore, previous setups leave room for improvement regarding the user's immersive experience. This paper contributes to this line of research by presenting a UX case study on mobile advertising with a novel CAVE-smartphone interface. We conducted two experiments in which we evaluated the intrusiveness of a mobile locationbased advertising app in a virtual supermarket. The results confirm our hypothesis that context-congruent ads lessen the experienced intrusiveness thereby demonstrating that our setup is capable of generating preliminary meaningful results with regards to UX. Furthermore, we share insights in conducting these studies.

Today, consumers expect companies to be socially responsible. However, the literature is undecided about the effects of communicating one's corporate social responsibility activities to consumers. This raises the question of how sustainability-driven companies can best advertise their products to stimulate ethical consumption: using self-benefit frames, where the main beneficiary is the consumer, or using other-benefit frames, where the main beneficiary is a third party. Using three experiments, this study examines the effect of other-benefit (vs. self-benefit) advertising frames on consumers' impulse purchases from sustainability-driven companies. Increasing impulse purchases can help such companies to strengthen their competitive positions. Additionally, it is studied to what extent two types of justification (moral versus deservingness) explain the proposed effect of advertising frames. The results show that only other-benefit frames affect impulse buying behavior, both directly, as mediated by moral justification. This study's insights may help sustainability-driven companies to decide on their advertising strategies by providing evidence that other-benefit-framed advertisements are more effective in enhancing impulse purchases than self-benefit-framed advertisements.
