What is Open webOS?



Hp-webos-20.jpg


webOS on a HP / Palm Pre 2 Smartphone in “card view” (showing running apps grouped together)



Open webOS is an open-source mobile operating system based on Palm webOS, which was originally developed by Palm Inc. and released on the Palm Pre Smartphone in June 2009. webOS has its roots in Linux, but features a UI and application framework built on top of web technologies such as HTML5, JavaScript, and CSS. Rendering of the UI is achieved through a custom WebKit engine codenamed “Luna”.


Following its acquisition of Palm Inc. in April 2010, Hewlett Packard (HP) re-wrote webOS to include tablet support, ahead of the HP TouchPad’s ultimate release in July 2011. After a surprise decision to halt all production, sales and future development of webOS-based hardware in August 2011, HP decided to release an open source version of the webOS operating system. Open webOS was officially released in September 2012 . On 25 February 2013, HP announced the sale of its remaining webOS division to LG Electronics, who are still actively contributing to the Open webOS code base.


Detailed information on the history and technical aspects of webOS / Open webOS can be found on the webOS Wiki and on the Open webOS Project site.




What made webOS unique?




The design of the webOS UI was led by current Director of Android User Experience at Google Inc., Matias Duarte. The design language was elegant, whilst still preserving the simplicitiy principles that made the original Palm OS successful (aka Zen of Palm).


Unique features of webOS included:

  • The original card-based multi-tasking interface (including live-view, stacking, reordering and flick to dismiss apps / cards)
  • Unobtrusive, actionable notifications
  • Extensive support for gestures
  • Synergy synchronization
  • Native Adobe Flash support
  • Just Type Universal Search
  • Wave Launcher
  • Easy access to true Developer Mode (Root Access) through use of the Konami code or special keyword
  • Palm Online Profile device backup and synchronization to the cloud
  • The first implementation of an “Over The Air (OTA)” update mechanism to provide webOS users with the ability to receive OS updates directly on their Smartphones.


Screenshots and a more detailed explanation of each of these unique features is in the next section[LINK].


webOS also has an active and committed Homebrew Community that is largely driven by WebOS Internals, the developers of an application called Preware. This application is essentially a portal that provides direct access to homebrew apps and UI / System customizations developed under an unique patching sytem that did not require tethering to a computer, and also provided the ability to easily revert changes made.




Detailed look at webOS unique features



Multi-tasking interface *

In webOS, "cards" are used to represent apps and manage multitasking. Users switch between running applications with a horizontal swipe between screens when in “card view”. Closing applications are achieved by flicking a "card" up and "off" the screen. The application "cards" can also be grouped together by stacking the cards on top of each other. They can also be simply re-arranged by touching and holding the card.

Unobtrusive, Actionable Notifications *

The webOS notification area is located on the bottom portion of the screen on smartphones, and on the top status bar area on tablets.

When a notification is recevied on webOS smartphones, the notification area slides in slightly from the bottom of the screen and displays a small notification icon for the relevant app(s).




<SCREENSHOTS GOES HERE>


Receiving notifications (collapsed view) on webOS-based smartphones (left) and tablets (right)



Users can tap on the notification area to see an expanded view of the notifications, which will result in the notification area sliding in even further from the bottom of the screen. In the expanded view, actionable notification banners similar to those in the Android (> 4.1) notification pulldown are shown. Previews of contents of the notification can also be shown in this view. Just like Android (> 4.1), notification banners can be dismissed by swiping the notification to the side of the screen.

Receiving notifications (expanded, actionable view) on webOS-based smartphones (left) and tablets (right)



When multiple notifications from the same app are received, the banners will be aggregated and a notification badge displayed. Users can either action (tap) / dismiss (swipe) individual / grouped notifications.

Due to the resizable nature of the Mojo and Enyo application frameworks used by webOS, applications will automatically resize themselves to allow unhindered use while notification icons are displayed. After focus is returned to the application, the notification area returns to a smaller slide-out where only small notification icons are visible. The user can again tap on the icons to expand them.



Extensive support for gestures

Early Palm / HP smartphones based on webOS had a dedicated “gesture area” below the screen, where users could perform a number of different gestures like enter card view, go back and go forward. Whilst the HP TouchPad did not have a dedicated gesture area, it did allow for some minor gestures by detecting when touch input comes in from the edges of the screen. A Gesture Guide (LINK http://www.engadget.com/2009/05/25/leaked-palm-pre-gesture-guide-lets-you-get-some-finger-flicking/) outlining supported gestures accompanied the Palm / HP Pre Smartphones.

Some examples of gestures available on the HP and Palm Pre Smartphones



Synergy Synchronization*

Users simply add their various online accounts into the account management app and the operating system automatically integrates and combines information from all these sources. For example, Users can sign into multiple email accounts from different providers and integrate all of these sources into a single list. Similar capabilities pull together calendars and also instant messages and SMS text messages from multiple sources.





Just Type Universal search

Just Type is a powerful, universal search box, application launcher, and task / action box. To use the feature, users simply type something into the input box and Just Type will start searching the phone for apps, messages, documents, contacts, files and other items that match the input. It will also provide quick actions such as the ability to press a button that allows you to search the web or post the input directly to Facebook or Twitter as a status update.

Developer Mode

webOS was built to be Developer friendly. Obtaining root-level access was as simple as enabling Developer Mode, which could be achieved by either typing the Konami code {LINK} or “webOS20090606” into the Just Type box and then opening the “Enable Developer Mode” app.
