Multimedia/Media Viewer/it



Questo è il project hub per Media Viewer, un nuovo strumento sviluppato dal gruppo multimediale della Fondazione Wikimedia. Per una veloce panoramica su questo progetto visita 'A proposito di Media Viewer'.

Media Viewer mira a migliorare l'esperienza visiva per lettori e contributori occasionali su Wikipedia e sui siti Wikimedia.

Questo nuovo browser multimediale mostra le immagini in un formato più grande, con utili informazioni sui loro contenuti, sui loro autori e relativi metadati. Inoltre offre una serie di funzionalità per ingrandire, condividere, scaricare o incorporare i file multimediali, come descritto di seguito.

Media Viewer è stato testato estensivamente durante lo sviluppo, attraverso studi di usabilità,consultazioni della comunità e indagini online. Sulla base di questi riscontri, il gruppo multimediale ha sviluppato una serie di nuovi miglioramenti, al fine di rendere Media Viewer più semplice da usare per i lettori e i contributori occasionali, i principali destinatari di questo strumento.

Ciò che è stato imparato dallo sviluppo e dall'osservazione di Media Viewer nel corso della produzione è disponibile nella forma di una retrospettiva e di un rapporto di ricerca.

Ci si aspetta che nel corso del tempo queste funzionalità incoraggino gli utenti occasionali a contribuire maggiormente a Wikipedia ed ai progetti fratelli Wikimedia.

Utenti
Gli utenti principali per Media Viewer sono:


 * lettori
 * contributori occasionali

Altri utenti sono:


 * editori esperti
 * contributori

User Stories
Abbiamo intenzione di supportare tutti questi gruppi di utenti, dando un'attenzione iniziale maggiore ai lettori per quanto riguarda la prima versione. Leggi qui sotto quali sono le esigenze di ogni tipologia di utenti.

Reader stories
Come lettore voglio:


 * visualizzare le immagini in formati più grandi
 * trovare le informazioni principali
 * navigare tra immagini attinenti tra loro
 * condividere il collegamento ad un'immagine
 * usare una interfaccia semplice e senza disturbi visivi
 * visualizzare le immagini nella stessa pagina (non in un altro sito)
 * tornare facilmente all'articolo

Casual editor stories

Vedi anche questa visione multimediale per trovare esempi su come Media Viewer potrebbe essere usato dalle diverse tipologie di utenti nei prossi anni.

Problemi
Le indagini tra gli utenti suggeriscono che l'attuale pagina del file presenta per i lettori diverse problematiche:


 * troppe informazioni
 * disturbi nella visualizzazione
 * testo preponderante rispetto all'immagine
 * porta ad una pagina a sè stante (su un altro sito, p.e. Commons)
 * oppure porta ad una pagina uguale (sullo stesso sito, p.e. Wikipedia italiana)
 * tempi di caricamento più lunghi

While this file page design works for advanced users, it is often confusing for casual users.

Solution
Media Viewer offers a practical solution for readers, by making it easier to:


 * preview larger images
 * enlarge images
 * browse related files
 * read image captions
 * see a short summary
 * do all this over the same page you're on

Readers can also get more details on the file page, with a prominent button that provides quick access to all the metadata.

Experienced users can easily bypass or disable Media Viewer, if they prefer to go straight to the file page.

How does Media Viewer work?


To open an image in Media Viewer, click on its thumbnail on any article, gallery or category page. This will display a larger image in Media Viewer, right over the page where you clicked. We call this the 'lightbox view'.

Immagine
L'immagine viene mostrata in un formato più grande su uno sfondo nero, in un primo piano che riempie per intero la pagina in cui è stata cliccata la miniatura. Ciò fa risaltare maggiormente l'immagine ed elimina alcuni disturbi visivi tipici delle pagine ricche di testo.

Strumenti
These tools are provided to the side of the image:


 * Close button (goes back to article view)
 * Full screen button (expands into full-screen view, see below)
 * Disable / Enable button
 * Next and Previous buttons
 * Download button
 * Share / embed button
 * Enlarge function (click on any image to go to its full-resolution file)
 * 'More details' button (goes to the File: page)

The 'full-screen view' shows the large image across the entire screen (not just the browser window), with minimal information and buttons available on hover. This view lets you focus exclusively on the image, with no other distractions. In this mode, you only see the controls, the file name and the author/source/license if you hover over the image.

The Disable/Enable, Download and Share/Embed buttons open up small panels over the image. The Enlarge and 'More details' functions go to a separate page.

Informazioni Principali
Here is the most important information that is shown prominently, right below the image:


 * Image caption or description (Golden-crowned Sparrow)
 * Author (e.g. Alejandro Erickson)
 * Source (e.g. Bird Institute)
 * License Info (e.g. CC-BY-SA-2.0)

Informazioni Secondarie
Here is the information that is shown below the fold, once you open the metadata panel (by scrolling down or pressing up/down arrow keys):


 * Description (if not already shown)
 * Uploader name (e.g. Smallbones)
 * Creation or Upload Date (e.g. 12 April, 2012)
 * Location (e.g. geo-tags, if any)
 * License details (e.g. special credits or restrictions)
 * More meta-data can be added to this panel, as needed (e.g.: file name).

These features are available every time you click on a thumbnail to open Media Viewer, as long as the tool is enabled. Media Viewer is now enabled by default on all Wikimedia sites, but can be disabled by any user, as described here. From a file description page, click on "Open in Media Viewer" below the image to view it with this tool.

Nuovi Miglioramenti
The Wikimedia Foundation's multimedia team developed a range of new improvements, based on community feedback and usability research.

Here are some of the key improvements that were released in November:


 * an easier way to enlarge images
 * a more prominent button linking to the File: page
 * image captions right below the image
 * clearer icons for Download and Share
 * an easier way to disable the tool for personal use
 * a way to re-enable Media Viewer

Here are screenshots showing what some of these improvements look like:

How you can help
If you find a technical issue with Media Viewer, please file a bug here on Phabricator.

You can also post your report on this discussion page, with a screenshot and information on your browser and operating system :).

Before reporting a bug, check first that this issue is not already on this list of known bugs. In case it’s already been fixed, you may also want to test it on this test page on MediaWiki.org -- where new features are released a week before the rest of the wikis.

Work in progress can usually be tested on this beta site, where new features are rolled out before going to production.

Note: Media Viewer only supports the most widely used image file formats on Wikimedia sites (e.g.: JPEG, GIF, PNG, TIFF, SVG). In future releases, we plan to add support for more file formats, such as PDF, audio and video files.

Development
Media Viewer was developed by the Wikimedia Foundation's multimedia team from July 2013 to November 2014. It was designed in collaboration with community members, in a series of discussions held over video conferences, IRC, and face-to-face meetings. This tool was then developed and tested as a Beta Feature through April 2014, when it was gradually released worldwide, over a three-month period.

Based on user feedback, a wide range of improvements were developed to make Media Viewer easier to use, such as: an easier way to enlarge images, image captions, and an easier way to disable the tool for personal use.

Feature development has now ended for this project.

Riscontri
Media Viewer was tested extensively with millions of readers and casual editors, the primary target users for this tool.

User feedback was collected through a variety of methods:


 * user research
 * usability tests
 * discussion pages
 * online surveys
 * community consultations

Please check the links above for more information about these different sources of user feedback.

Over 18,199 feedback responses about Media Viewer were collected as part of a wide online survey hosted in multiple languages, from April to July 2014. A majority of global respondents found the tool "useful for viewing images and learning about them" (56% "useful", 35% "not useful", 9% "not sure"), based on total unweighted survey results, as shown on this spreadsheet. When weighted to match global Wikipedia readership for each language, fewer respondents found the tool "useful" than "not useful" (39% "useful", 50% "not useful", and 10% "not sure"). Cumulative "useful" approval ratings by language: English 36%, French 70%, Spanish 78%, Dutch 59%, Portuguese 81%, German 30%, Hungarian 63%, Catalan 71%. Readers tended to view the tool more favorably than advanced users. These approval ratings increased over time in all languages, suggesting that users found Media Viewer more useful for viewing images over time, as new improvements were developed based on feedback. Note that this was an optional survey, so approval rates should not be cited as a conclusive metric, as they are subject to self-selection bias (just like RfCs cited below).

Five requests for comments (RfCs) about Media Viewer were initiated by community members in the summer of 2014: two on the English Wikipedia, two on the German Wikipedia, and one on Wikimedia Commons. These RfCs typically involved up to a couple hundred contributors at a time, with low participation from readers, the target users for this product. Feedback from these RfCs shows that a majority of participants (including every single "reader" and "casual editor") believed that the "Media Viewer" should be disabled by default for all users, logged-in or not, and either left as an opt-in feature or scrapped altogether. Aside from any technical shortcomings, discontent was also shown with the manner in which the project was conducted and the lack of transparency shown by the team responsible.

Codice
The code for Media Viewer is made possible by two separate extensions:


 * Multimedia Viewer Extension - the front-end extension that displays media files and information
 * Commons Meta Data - the back-end API that serves information to the Media Viewer

Future Versions
Feature development has now ended for this version of Media Viewer. In future versions, the multimedia team will consider adding more features requested by our community, such as a better zoom tool, a Mobile Media Viewer and/or support for more file formats (e.g. slides, video, audio, as shown in these slides).

Here are some features that may be considered for future versions:


 * Zoom on this file
 * Show file collection panel
 * View files in slideshow mode
 * Show PDF slides
 * Play Video files
 * Play Audio files
 * Support Developer Plugins
 * Mobile Media Viewer

Future versions could also include feedback tools below the image (e.g. thank, flag), as suggested by this 2016 multimedia vision, as well as best practices from other media sites. For an overview of other features that could be considered for these future versions, check the annual multimedia plan for 2014-15.
