A touchless gestural system for extended information access within a campus
2017
In the last two decades, we have witnessed a growing spread of touchless interfaces, facilitated by higher performances of computational systems, as well as the increased availability of cheaper sensors and devices. Putting the focus on gestural input, several researchers and designers used Kinect-like devices to implement touchless gestural interfaces. The latter extends the possible deployments and usage of public interactive displays. For example, wall-sized displays may become interactive even if they are unreachable by touch. Moreover, billboard-sized displays may be placed in safe cases to avoid vandalism, while still maintaining their interactivity. Finally, people with temporary or …
Gesture recognition using low-cost devices: Techniques, applications, perspectives
2016
Negli ultimi anni abbiamo assistito ad una grande diffusione dei cosiddetti “Kinect-like devices”, ovvero dispositivi basati su un insieme di sensori a basso costo, che consentono di ottenere un’immagine di profondità della scena ripresa. L’alta accessibilità di questi dispositivi, principalmente in termini di costi, ne ha facilitato la diffusione nell’ambito del riconoscimento dei gesti in numerose applicazioni, sia commerciali che di ricerca. In questo articolo saranno inizialmente illustrati i principi generali su cui si fondano le principali tecniche utilizzate per riconoscere i gesti, sfruttando i dati ottenibili dai dispositivi “Kinect-like”. Successivamente, saranno presentati alcuni…
A Multimodal Fruition Model for Graphical Contents in Ancient Books
2016
One of the most common and efficient way to preserve ancient books is to digitize them, and make their content someway browsable. However, this process often does not take into account the fruition point of view. Exploiting the currently available technologies allows for new ways of content fruition, to attract more people and help them to better understand the available information. In this paper, we present a solution for an innovative and multimodal exploration of ancient books contents, using both touch and touchless gestures. This allows people for both near and far distance interaction, which results in different interaction models.
Elicitation and evaluation of zoom gestures for touchless interaction with desktop displays
2019
Touchless gestural interaction has been widely studied and adopted in many contexts. Furthermore, the growing availability of low-cost enabling devices, such as Kinect or Leap Motion, boosted up the interest in such interaction both for commercial and scientific purposes, both for large public displays and for personal displays. The problem of choosing the right touchless gesture for the right action is thus still an open issue, depending on several aspects, such as context, purpose, users' culture, etc. In this work, we first present the results of a gesture elicitation study that allowed us to identify a set of touchless gestures for performing zoom actions while interacting with desktop …
