Tweaks - LunaCE Gesture DetectionWhen HP released their Open Source "

" for the HP TouchPad (not to be confused with ), the group at was able to package up those changes along with a bunch of enhancements and released it as (pronounced lunacy") in Preware. LunaCE is currently in beta so you will need to go through the process to set-up the beta feeds in Preware, which can be found at testing.preware.org. In addition, you will need to have installed on your TouchPad to toggle any of the new enhancements.

One enhancement that is available in LunaCE is the ability to adjust the Gesture Detection method when swiping in from the bottom of the screen (as long as you have ) to minimize your app. You have three options that you can choose from by opening up Tweaks and navigating to the Luna section

  • Swipe - You need to perform a fast swipe up from the bottom of the device and the gesture will be detected when you pull your finger up from the screen. If you perform a slow swipe up, nothing will happen.  This is the closest option to the stock webOS 3.0.5 experience
  • Slide - No matter how quickly or slowly you swipe up, you just need to swipe up 15 pixels from the bezel of the device. You do not need to even lift your finger from the screen, just swipe past that 15 pixel line and the gesture will activate
  • Fluid - This option provides the most natural option where the device actually tracks your finger and will show the transitional state of the app from active to being minimized. If you pick up your finger before the app is fully minimized, it will snap back to full screen

Regardless of your choice, LunaCE does provide one additional major improvement to the webOS experience. On a stock TouchPad, a swipe up from the bottom may minimize your app to card mode, but it will also interact with the app. So if you are reading a webpage it will scroll that page, if you have a drawing app up it may draw a line on your swipe, or if you are playing a game that swipe may cause an unanticipated action. In LunaCE, all swipes from the bezel of the device no longer affect the current app, which is a great thing!

      Build Your First App for webOS TV
      Web apps are written using HTML with copious amounts of CSS and JavaScript for style and functionality. Any modern Web browser can deliver this type of apps to the user.  With webOS TV, web apps are elevated to the lofty title of a first class citizen - web apps on webOS TV are given access to the same hardware, and OS features that typically available to native apps.
       
      Web apps built for webOS TV are very similar to standard web apps. Like the standard web applications, you can create web apps for webOS TV using standards based web technologies like HTML, CSS, and JavaScript. Anyone with experience in building web applications can easily start developing web apps for webOS TV.
       
      Now, just create your app using the CLI.
      Run the webOS TV CLI.
       
      Create new app with Enyo bootplate.
      ares-generate -t moonstone-2014 first-app Now you can continue developing and testing your app.
       
      Edit ./first-app/appinfo.json file. Update "id" and "title" properties in appinfo.json file with text editor as below.
      {
          "id": "com.yourdomain.app.firstapp",
          "version": "0.0.1",
          "vendor": "My Company",
          "type": "web",
          "main": "index.html",
          "title": "singlepane",
          "icon": "icon.png",
          ...
      }
       
      Package your app from app directory. If app is packaged successfully, you can see the created .ipk file.
      ares-package first-app  
      Run the webOS TV Emulator.
       
      Install your app to emulator. Be sure to use the correct file name for your package.
      ares-install com.yourdomain.app.firstapp_0.0.1_all.ipk  
      Launch your app on emulator.
      ares-launch com.yourdomain.app.firstapp
