@article{4381, abstract = {{This article reports on two user studies exploring the knowledge of end users about technical processes of technology-enhanced home environments, which are often assumed to play an important role for attitudes such as privacy and security. In the first study (n=12 participants between 19-71 years of age), we analyzed user knowledge about technical processes using the teach-back methodology. In the second study, we additionally applied new developed questionnaires and analyzed participants’ data (n=24 participants between 19-76 years of age) regarding relations of user factors, users’ knowledge about technical processes and attitudes such as privacy and security of technology-enhanced environments. In contrast to existing assumptions, the results showed that general structural knowledge about technical processes was not related with attitudes such as privacy and security. Additionally, we found that most participants had only relatively superficial knowledge about technical processes, which was further influenced by age and technology experience.}}, author = {{Sack, Oliver and Röcker, Carsten}}, isbn = {{2332-3477}}, issn = {{2332-3485 }}, journal = {{Universal Journal of Psychology}}, keywords = {{Technology-enhanced Environment, Ambient Assisted Living, Mental Model, Teach Back, Privacy, Security}}, number = {{2}}, pages = {{72 -- 83}}, publisher = {{Horizion }}, title = {{{Privacy and Security in Technology-Enhanced Environments: Exploring Users’ Knowledge about Technological Processes of Diverse User Groups}}}, doi = {{10.13189/ujp.2013.010207}}, volume = {{1}}, year = {{2013}}, } @inproceedings{4483, abstract = {{Technology-enhanced homecare environments mark a big step towards increased quality of life for elderly and disabled people at home.

While the assumption of a fundamental trade-off is widely accepted in state-of-the-art research, this paper disputes the predominant hypothesis. Instead, it is argued, that the trade-off is not of fundamental nature, but caused by neglecting elementary aspects in the design process. In order to verify this line of argument, a novel interface concept for mediating socio-emotional awareness information is presented. To verify the validity of the conceptual approach, several evaluations were conducted. The evaluations verified the approach of this paper and showed, that a cautious interface design can enhance user privacy in multi-user awareness systems and minimize disruptive effects on primary tasks, without reducing awareness mediation and usability.}}, author = {{Röcker, Carsten and Magerkurth, Carsten}}, booktitle = {{Universal Acess in Human Computer Interaction : Coping with Diversity}}, editor = {{Stephanidis, Constantine}}, isbn = {{978-3-540-73278-5}}, keywords = {{Privacy, Interruptions, Team Awareness Systems, Dual Trade-Off : Evaluation}}, location = {{Beijing, China}}, pages = {{273--283}}, publisher = {{Springer}}, title = {{{Privacy and Interruptions in Team Awareness Systems}}}, doi = {{10.1007/978-3-540-73279-2_31}}, volume = {{4554}}, year = {{2007}}, } @inproceedings{4816, abstract = {{This paper presents a novel concept for personalized privacy support on large public displays in intelligent home environments.
