Instant WebKiosk is a free and refined “live” (no installation required) browser-only (only the browser interface will show up) operating system based on Linux Debian and designed for use in web kiosks, multi-user “web workstations” (cafès, offices, schools, hotels) and digital signage deployments. It makes use of Google Chromium as Internet browser and it features audio support, video files support, Adobe Flash support, PDF and images viewing, office files and compressed files support; it features full “i18n” (internationalization) including CJ input methods and a very useful on-screen virtual keyboard for touch devices. Instant WebKiosk protects your privacy even if it’s fully customizable: users can change its settings (or install “apps” from the Chrome Web Store) but, thanks to its “live” nature and design, after a reset the operating system presents itself with the default settings and users’ private informations are completely destroyed. Instant WebKiosk boots form USB flash devices (in order to write the downloaded IWK ISO file to a USB stick, Windows users can use Win32DiskImager, while Linux users can make use of dd) and supports the same hardware that default Debian Linux distributions do – no less… no more. Supported file types in detail: Instant WebKiosk can read txt, html, xml, gif, jpeg, png, psd, mpeg, mp3, mp4, avi, wmv, wma, asf, mov, 3gp, ogg, ogm, mkv, rm, wav, dts, aac, flc, flv, midi, pdf, csv, doc, xls, ppt, rtf, odt, ods, odp, and zip files. All known unsupported file types are filtered. …and there’s more: Instant WebKiosk for Raspberry Pi is an IWK-derived operating system for the well known Raspberry Pi micro-computer!
