In this paper, we present the design process of a smart bracelet that aims at enhancing the life of elderly people. The bracelet acts as a personal assistant during the user's everyday life, monitoring the health status and alerting him or her about abnormal conditions, reminding medications and facilitating the everyday life in many outdoor and indoor… (More)
"Eyes on the road, hands on the wheel" is a crucial principle to be taken into account designing interactions for current in-vehicle interfaces. Gesture interaction is a promising modality that can be implemented following this principle in order to reduce driver distraction and increase safety. We present the results of a user elicitation for gestures… (More)
The ubiquitous computing era is bringing to the human the possibility to interact always and everywhere with digital information. However, the interaction means used to access this information exploit only few of the human sensorimotor abilities. Most of these interactions happen through traditional desktop or mobile interfaces, which often involve just… (More)
This paper presents the concept of a lamp that allows displaying and collecting user's emotional states. In particular, it displays the emotional information changing colors and facial expressions; in fact, the lamp is characterized by anthropomorphic form and behavior in order to make the interaction more natural and spontaneous. The user can interact with… (More)
In this paper, we present a novel opportunistic paradigm for in-vehicle gesture recognition. This paradigm allows using two or more subsystems in a synergistic manner: they can work in parallel but the lack of some of them does not compromise the functioning of the whole system. In order to segment and recognize micro-gestures performed by the user on the… (More)
In this paper, we describe a natural interface based on microgestures performed on a steering wheel and recognized through the driver's electrical muscular activity. This approach is based on a wearable paradigm of interaction, in which the sensors are placed on the user's arm. The wearable system communicates with the infotainment system of our prototype… (More)
Physical contact has an important role in human well-being. In this paper, we present Hugginess, a concept of interactive system that encourages people to hug by augmenting this gesture with digital information exchange. As a proof of concept, we developed two t-shirts that reciprocally send information to the hugged person through the conductive fabric.
This paper presents a non-intrusive approach for view-invariant hand gesture recognition. In fact, the representation of gestures changes dynamically depending on camera viewpoints. Therefore, the different positions of the user between the training phase and the evaluation phase can severely compromise the recognition process. The proposed approach… (More)
