• Conference Proceeding: An Effective Mobile Monitoring for Patients at Risk of Fainting

  Giovanna Sannino, Aniello Minutolo, Giuseppe De Pietro
  [show abstract] [hide abstract]
  ABSTRACT: In this paper we present a mobile monitoring system able to collect information about the patient’s health condition during his stay in the so-called hot waiting room for a nuclear medicine department. The proposed system automatically monitors some vital parameters such as Heart Rate and Oxygen saturation and also information about posture and movements. The collected data is processed through a rule-based Decision Support System (DSS), implemented on a mobile device, and capable of automatically generating alarms if a dangerous situation occurs. The tests have demonstrated that the system was extremely successful.

• Article: Design and Comparative Evaluation of Smoothed Pointing a Velocity-oriented Remote Pointing Enhancement Technique

  Luigi Gallo, Aniello Minutolo
  [show abstract] [hide abstract]
  ABSTRACT: The increasing use of remote pointing devices in various application domains is fostering the adoption of pointing enhancement techniques which are aimed at counterbalancing the shortcomings of desk-free interaction. This paper describes the strengths and weaknesses of existing methods for ray pointing facilitation, and presents a refinement of Smoothed Pointing, an auto-calibrating velocity-oriented precision enhancing technique. Furthermore, the paper discusses the results of a user study aimed at empirically investigating how velocity-oriented approaches perform in target acquisition and in trajectory-based interaction tasks, considering both laser-style and image-plane pointing modalities. The experiments, carried out in a low precision scenario in which a Wiimote was used both as a wand and a tracking system, show that Smoothed Pointing allows a significant decrease in the error rate and achieves the highest values of throughput in trajectory-based tasks. The results also indicate that the effectiveness of precision enhancing techniques is significantly affected by the pointing modality and the type of pointing task.

• Conference Proceeding: Smoothed Pointing: a User-Friendly Technique for Precision Enhanced Remote Pointing

  Luigi Gallo, Mario Ciampi, Aniello Minutolo
  [show abstract] [hide abstract]
  ABSTRACT: This paper presents Smoothed Pointing, a velocity-based precision enhancing technique for remote pointing by means of absolute devices. After discussing the most recent related work concerning the problem of accuracy in remote pointing by handheld input devices, we introduce the distinctive features of the Control-Display adaptation technique we have designed to: i) reduce the effect of both noise in input device signals and of hand tremors on the cursor stability; and ii) increase the accuracy of pointing when performed on large, high resolution displays. Moreover, we describe a 10 second calibration procedure to determine the filtering parameters, so as to free the user from a manual set up.

• Article: Realistic vs. Magic Interaction Metaphors in Virtual Environments

  Luigi Gallo, Giuseppe De Pietro, Aniello Minutolo
  [show abstract] [hide abstract]
  ABSTRACT: Virtual Reality (VR) technologies make it possible to reproduce faithfully real life events in computer-generated scenarios. This approach has the potential to simplify the way people solve problems, since they can take advantage of their real life experiences while interacting in synthetic worlds. In order to convey the users’ knowledge to the VR context, interaction metaphors are used. They can be either realistic, i.e. based on real world rules, or magic. In this paper we discuss the subject of interaction metaphors and outline the pros and cons of realistic vs. magic approaches. We also present our experience in the development of interaction techniques in a practical scenario, and suggest an approach to design effective 3D interaction metaphors.

• Conference Proceeding: A Natural Pointing Technique for Semi-Immersive Virtual Environments

  Luigi Gallo, Aniello Minutolo
  [show abstract] [hide abstract]
  ABSTRACT: Several interaction metaphors and techniques have been proposed to allow a natural interaction in virtual environments. Usually all these techniques are designed to be used with input devices such as wands, 3D mice or gloves. However, the availability of a new generation of auto-stereoscopic displays now makes it possible to exploit virtual experiences in new scenarios. In this paper we propose a variation of the ray-casting technique suitable for use with a standard mouse. With this proposed technique, users can move a 3D cursor in the virtual world without worrying about the third dimension and without losing the level of immersion provided by the 3D display.
