This work proposes the preliminary results of a system to recognize deception from facial micro-expressions. The adopted method starts from facial landmarks to analyze the micro-dynamics underlying the facial modifications. The procedure is repeated both while answering neutral questions (entailing no reason to lie) and when answering questions whose responses may cause harm or embarrassment, at least. The preliminary results invite us to continue the research of suitable features to tackle the problem of deception detection.

Cross-reality (CR) applications allow users to utilize tools for problem solving that reside on different points of the Milgram reality-virtuality spectrum. Design guidelines for such applications are missing. In this paper, we are proposing a design space focusing on single-user Cross Reality applications as a tool for guiding research and development projects.

Smart things are everywhere: smart watches, smart jewellery, smart art installations. All have in common the capability of sensing with input devices (e.g., buttons), computing, reacting with output devices (e.g., light matrices), and connecting with other smart things. Engaging their end users in their design can be challenging and yet give end users unique empowering opportunities. Toolkits are fundamental for engaging end users and enabling them to design. This paper presents the IoTgo phygital toolkit for smart-thing design with end users who are not experts, e.g., artists and school learners, which results from co-design actions and interventions in the field.

Immersive technologies such as Augmented Reality afford to enrich the physical environment with a layer of digital information, providing new experiences that can support and improve the daily life of people in their homes. We present insights from a field study with nine families to understand user experience and expectations of Mobile Augmented Reality at home and reveal emerging designs. We deployed a mobile application that provided a contextual representation of the WiFi signal through visualizations integrated in the physical space. Each family lived with the prototype for one week, with a pre- and post-study interview session. We found that Augmented Reality has potential to (1) foster people's autonomy and control (e.g., configuration of technology and problem solving), as well as (2) enhance people's knowledge and awareness about domestic technology (e.g., understanding technical terms and awareness of invisible infrastructures).

The Twitter has become a powerful medium for people to express their feelings and reactions towards some recent event or happening event. Analyzing and exploring such tweet data gives us in-depth understanding of the underlying event from people perspectives. In this work, we use the power of visualization to explore people’s tweets regarding the COVID-19 pandemic from the time period between April 2020 and March 2021. We use a number of visualizations targeting to show the sentimental polarity of people’s tweets over time and important keywords in people’s tweets and their evolution over time. The resulting visualizations give us an opportunity to explore people’s feelings and reactions during a whole pandemic year and to see how it evolved over time.

This paper describes the development of Remembering the City, a digital and public humanities project on an urban scale, which takes advantage of augmented reality techniques in order to bring memories of the Holocaust victims to the surface of the urban fabric. The project has been built in conjunction with the Stolpersteine (Stumbling Stones), the largest decentralized monument in Europe dedicated to the Holocaust, allowing for the first time a contextual access to information related to the stones. The paper describes the conceptual design of the project, the technical challenge of tracking bi-dimensional objects in the outdoors and the ethical concerns. The iterative development led to prototypical implementations that were tested with two evaluation studies, performed respectively with 10 volunteers aged between 30 and 50 and 22 students from a local high school. Both studies provided valuable feedback and directions for future development.

The spread of sensors and intelligent devices of the Internet of Things and their integration in daily environments are changing the way we interact with some of the most common objects in everyday life. Therefore, there is an evident need to provide non-expert users with the ability to customize in a simple but effective way the behaviour of these devices based on their preferences and habits. This paper presents RuleBot, a conversational agent that uses machine learning and natural language processing techniques to allow end users to create automations according to a flexible implementation of the trigger-action paradigm, and thereby customize the behaviour of devices and sensors using natural language. In particular, the paper describes the design and implementation of RuleBot, and reports on a user test and lessons learnt.

In this paper, we introduce Sparkle Glyphs - a glyph design that can be used to represent temporal multivariate data in a compact yet expressive way. One application scenario involves the analysis of multivariate audio features. These features are compared with sketch-based associations of sounds to identify and derive dominant perceived audio features.
