Smartphones and tablets are increasingly used to scan visual codes that act as physical hyperlinks to digital information. Compared with the outstanding performance of enterprise laser scanners, smartphone cameras suffer from defocus and motion blur. In this project, we propose to turn every smartphone into an enterprise-grade barcode scanner by adapting the latest research results in photograph restoration to the very specific properties of barcode images.

This paper presents Capital Music, a mobile application enabling real-time sharing of song choices with collocated urban dwellers. Due to the real-time, location-based peer-to-peer approach of the application, a user experience study was performed utilising the Wizard of Oz method. The study provides insight into how sharing non-privacy sensitive but personal data in an anonymous way can influence the user experience of people in public urban places. We discuss the findings in relation to how Capital Music influences the process of "cocooning" in public urban places, the practice of designing anonymous interactions between collocated strangers, and how the sharing of song choices can create a sense of commonality between anonymous users in the urban space. The outcomes of this study are relevant for future location-based social networking applications that aim to create interactions between collocated strangers.

In meetings, people sometimes come across information in the environment or in the conversation. This kind of accidentally encountered information may be or not be relevant to the main meeting topic, but stirs people's temporary interest and mediates group conversation. In some cases people even need to search these unexpected terms in the Web. This phenomenon is called opportunistic search. We question if digital displays can be designed to support opportunistic search in meetings. Assuming information sharing in collocated meetings may largely come from conversation, we propose to design an ambient tabletop display that provides just-in-time conversational information to support opportunistic browsing and searching. In this paper, we present our design explorations with user study, and answer some of the major design questions for such systems.

Physical products, things, and appliances will be associated with digital counterparts, such as additional product information, instructions, API's, etc.. Thus, it will become challenging for users to consciously manage access rights of data of their objects and stay aware of which data is visible to whom. This paper proposes to transfer the notion of Google's circles for managing social relationships to managing data streams of physical objects. We describe the concept and its implementation, and provide a proof-of-concept by a sample scenario. Thus, we show that object circles offer a more intuitive way for everyday users to manage the data-streams of their objects transparently.

This demonstration presents work done in the TimeMachine project with the goal to explore patterns in everyday life using a mobile application. This mobile application captures GPS data and uses this information to provide a subjective map of the user behavior using several visualizations. The project resorts to a rigorous data capture and processing approach with the goal of providing meaningful visualizations to the users. The visualizations depart from common map based representations as time is the main variable that is considered. Routines are represented through time based variables such as duration and frequency (for a given place or set of places) and a glimpse of the future is also provided considering what happened in the past. The demonstration presents the current version of the mobile application and desktop based tools used to extract information or prototype additional visualizations.

When applying the Wizard of Oz (WOz) method to mobile and ubiquitous computing studies, the task of the wizard becomes more difficult as observing the user requires the wizard to be in the context. We address this problem through the ConWIZ system that allows not only to control a specific prototype but also to control parameters included in the contextual settings. In order to evaluate our approach, we setup a study with eight human wizards where we evaluated the applicability, appropriateness and usability of the ConWIZ system for mobile and UbiComp environments. Each wizard had to simulate a navigation system and control contextual parameters like simulation of wind by switching a fan on and off, and tactile feedback mechanism using the ConWIZ system. All wizards stated that the tool is definitely applicable and appropriate for supporting a mobile WOz study which allows the wizard to be hidden also if he resides in the study context. Regarding the applicability of the system, we found out that high workload may hinder the wizard from doing additional tasks such as note taking.
当将Wizard of Oz (WOz)方法应用于移动和无处不在的计算研究时，向导的任务变得更加困难，因为观察用户需要向导处于上下文中。我们通过ConWIZ系统解决了这个问题，该系统不仅可以控制特定的原型，还可以控制上下文设置中包含的参数。为了评估我们的方法，我们建立了一个研究与八个人类向导，我们评估的适用性，适当性和可用性的ConWIZ系统在移动和UbiComp环境。每个向导都必须模拟一个导航系统，并控制环境参数，比如通过开关风扇模拟风，以及使用ConWIZ系统的触觉反馈机制。所有向导都表示，该工具绝对适用于支持移动WOz研究，如果向导驻留在研究环境中，则可以隐藏该工具。关于系统的适用性，我们发现高工作量可能会阻碍向导执行额外的任务，例如记笔记。

Searching for lost keys, wallets or mobile phones is a common nuisance. Compared to digital information, search support for physical objects is very limited. We propose Find My Stuff (FiMS) as a search engine for physical objects. We built a fully functional Arduino-based prototype. FiMS offers the users a simple search interface to locate tagged physical items in different indoor environments. A hierarchical search process ensures energy efficient and effective searches. Instead of a fixed search infrastructure, the localization system is based on SmartFurniture equipped with RFID readers and ZigBee modules. Search results provide intuitive search cues based on relative positioning to support users in the physical retrieval of their lost objects. The system requires no manual calibration and is robust against rearrangement of SmartFurniture. Safety mechanisms prevent abuse of the system and protect user privacy.

Pico projectors have lately been investigated as mobile display and interaction devices. We propose to use them as 'light beams': Everyday objects sojourning in a beam are turned into dedicated projection surfaces and tangible interaction devices. This way, our daily surroundings get populated with interactive objects, each one temporarily chartered with a dedicated sub-issue of pervasive interaction. While interaction with objects has been studied in larger, immersive projection spaces, the affordances of pico projections are fundamentally different: they have a very small, strictly limited field of projection, and they are mobile. This paper contributes the results of an exploratory field study on how people interact with everyday objects in pico projections in nomadic settings. Based upon these results, we present novel interaction techniques that leverage the limited field of projection and trade-off between digitally augmented and traditional uses of everyday objects.

Leaders stand out for what they say and how they say it. This work describes the impact of the language style of emergent leaders in small group discussions based on 7 hours of audio from English spoken discussions recorded with a ubiquitous platform. For the language style analysis, word categories are extracted from manual transcriptions of the discussions as well as from automatically detected keywords. The most relevant word categories are then used to predict the emergent leader in each group. Our findings reveal that non-privacy sensitive word categories like amount of words, conjunctions and assent are good predictors of emergent leadership. The emergent leader can be correctly inferred in a fully automatic approach with up to 82% accuracy using categories derived from keywords, and up to 86% using categories derived from full manual transcriptions.

In ubiquitous environments migratory interactive applications allow users to perform their tasks continuously across various devices. Users can push and pull migratory Web applications from one device to another for various reasons. However, the flexibility of such pervasive applications raises various security issues, such as the risk of theft of private information from the migrated user interfaces or the intrusion of malicious versions of the applications replacing the original ones. In this paper, we analyse such risks and present a number of solutions to address them in a client/server-based solution for supporting secure migration of interactive Web applications.
