“…The same also applies if the tag is picked up together with the phone. Techniques such as Shield&Share [10] might also be employed here to provide users with better control over privacy-related issues.…”

We present Phone Proxies, a technique for effortless content sharing between mobile devices and interactive surfaces. In such a scenario, users often have to perform a lengthy setup process before the actual exchange of content can take place. Phone Proxies uses a combination of custom NFC (near-field communication) tags and optical markers on the interactive surface to reduce the user interaction required for this setup process to an absolute minimum. We discuss two use cases: "pickup", in which the user wants to transfer content from the surface onto their device, and "share", in which the user transfers device content to the surface for shared viewing. We introduce three possible implementations of Phone Proxies for each of these use cases and discuss their respective advantages.

PriCal is an ambient calendar display that shows a user's schedule similar to a paper wall calendar. PriCal provides context-adaptive privacy to users by detecting present persons and adapting event visibility according to the user's privacy preferences. We present a detailed privacy impact assessment of our system, which provides insights on how to leverage context to enhance privacy without being intrusive. PriCal is based on a decentralized architecture and supports the detection of registered users as well as unknown persons. In a three-week deployment study with seven displays, ten participants used PriCal in their real work environment with their own digital calendars. Our results provide qualitative insights on the implications, acceptance, and utility of contextadaptive privacy in the context of a calendar display system, indicating that it is a viable approach to mitigate privacy implications in ubicomp applications.

“…enabling access to a personal clip board. In addition, mobile phones have been used as tokens to identify users of a shared interactive surface; an approach which enables diverse interactions (e.g., [21,22]). However, none of these papers considered opportunities for applying such interaction techniques to multiple items on an interactive surface.…”

Current interactive surfaces do not support user identification. Hence, personalized applications that consider userspecific access control are not possible. Diverse approaches for identifying and distinguishing users have been investigated in previous research. Token-based approaches -e.g., which utilize the user's mobile phone -are especially promising, as they also allow for consideration of the user's personal digital context (e.g., stored messages, contacts, or media data). However, existing interaction techniques are limited regarding their ability to enable users to manipulate (e.g., select or copy) multiple items at the same time, as they are cumbersome when the number of files exceeds a certain amount. We present MobiZone, a technique that enables users to interact with large numbers of items on an interactive surface while enabling personalized access by using the mobile phone as a token. MobiZone provides a spatial zone that can be positioned, resized and associated with any action according to the user's needs; items enclosed by the zone can be manipulated simultaneously. We present three interaction techniques (FlashLight&Control, Remote&Con-trol, and Place&Control) that enable users to control the zone. Additionally, we report the results of a comparative user study in which we compared the different interaction techniques for MobiZone. The results indicate that users are fastest with Remote&Control, and they also rated Remote&Control slightly higher than the other techniques. 6 It e m s S e le c te d 6 It e m s S e le c te d Figure 1: Using MobiZone, the user can control the position and size of the zone, which enables personalized interaction with multiple items via different techniques (FlashLight&Control, Place&Con-trol, and Remote&Control).
