Friday Forum Focus: Windows*8 development, gesture recognition, Unity

Once a month, we take a look at some of the most popular posts in the Ultrabook™ and Windows*8 forums here on the Intel Developer Zone, as well as notable blogs and articles.  Whether you’ve got a specific question or just want to chat with someone who loves coding as much as you do, these forums are the right place to do it. Click on any of the links to take part in the ongoing conversation.

Ultrabook™ and Windows* 8

Problem adding a .NET framework DLL as reference to Windows Store app

“We are building a Windows Store app (Windows 8 metro style) which searches content in documents. We have used Lucene.NET to generate the program database due its high performance as search engine. In a desktop program (Windows form) that we developed before, we achieved all the expected functionality provided by Lucene, so now we want to port our application to an Windows Store app to create a version for our Windows 8 tablet…..” keep reading

Will LSP (Layered Service Provider) work with Windows*8?

“The application was built with LSP (Layered Service Provider).  Will LSP (Layered Service Provider) work with windows 8?  Or does it need to be replaced with WFP and if so would anyone have code samples of how to do that?”….keep reading

HTML5/JS vs. XAML/C#

Getting the LABEL_EYE_CLOSED attribute

“I wrote a program to detect the attributes; all attributes are being detected correctly except the labels INDEX_EYE_CLOSED_LEFT and INDEX_EYE_CLOSED_RIGHT which always return 0.

Looking at the sample binaries I found that it does not provide this information either. Is it implemented? Or is it a bug?

I'm using UtilMPipeline and the OnNewFrame code is the following:”….keep reading

Getting Raw Finger Points

“Could anyone help me out, I am trying to just get the coordinates of the finger points so that I can set up some sort of custom gesture. I have tried looking at the sample application but I could not figure it out other then getting x and y from the draw method.”….keep reading

Moving Mouse Cursor Using Hand Gesture Using C#

“I am trying to do something like, my fingers or hand will be acting like mouse. Hand will control mouse cursor and hand openness state to thumb movement will act like a click of left mouse button.

I kind of done it but the code is very jittery, it’s not having smooth movement. Mouse cursor will not move smooth.”….keep reading

Recent Blog Posts in the Ultrabook Development Community

Meshcentral.com – Intel AMT Hardware KVM multi-display support

“Every few weeks, I try to add more Intel AMT support in Meshcentral.com. This time around, I added multi-display support for Intel AMT on the hardware KVM viewer. So, when you connect to Intel AMT KVM from meshcentral.com, you not only get the new power control icon that allows you to reboot, power on, power off the computer. If the remote computer has two or three displays hooked up to the built-in graphics adapter, you see a new icon that allows you to toggle between displays. I recorded a video demonstration of the entire process.”

Foliage Patch – Organizing Our Data

This blog post discusses how we organize our foliage data with patches.  The previous blog post (here) mentioned that we separate foliage rendering into full-3D objects near the camera, and 2D billboard proxies further away (and for small objects near the camera).  This data drives our rendering of both 2D and 3D objects.

Aside: We render plants.  I intentionally use the generic term “object” instead of “plant” because we could render other kinds of things: like rocks, twigs, mushrooms, trash, etc.  Though, “plant” will probably sneak in here and there.”

 Gain Perceptual Computing Skills, Innovate, and Win!

 PC technology is rapidly evolving beyond what we’ve known for 30 years.  The mouse and keyboard are no longer the only ways to interact with applications.  To support further advances in this exciting field, Intel has released the Perceptual Computing SDK, a free framework developers can use for their applications.  To excite the ecosystem and get early adoption and insights into the Perceptual Computing application experiences, Intel has created a number of Perceptual Computing focused programs and incentives such as the recent Ultimate Coder: Going Perceptual competition and the ongoing Intel® Perceptual Computing Challenge.  Additionally, Intel is starting a series of Perceptual Computing Workshops and Hackathons across the globe to help train developers on the Intel Perceptual Computing SDK. To kick this off we are happy to announce our initial events in the San Francisco Bay Area.”

 May 7th, 2013 AppLab for Windows*8 on Mobile Platforms

“Well, just last week I returned from one of our first Application Development Labs (AppLab) devoted to development on the Intel Platform on Windows* 8 for touch, sensor, and HTML5.  The event took place in Los Angeles (LA) California in the United States.   The presenters were drawn from Intel - including two of our brightest Technical Marketing Engineers - Meghana Rao and Gayathri Murali- and yours truly, Paul Steinberg, as host and emcee.”

Re-Imagining Apps for Ultrabook (Part 5): Device Motion

“The fifth part of our Re-imagining Apps for Ultrabook™ video series is now available. In it, I’ll provide an overview of device motion and walk through a few ways we can take advantage of this set of capabilities in the desktop apps we create.”

The Unity Multi-Touch (Finally)

“Here is the source for the CPP and C# files needed to implement the Multi Touch Plugin DLL referred to in the previous post. Sorry it took so long to publish. Just download the zip and they're both there. I've also uploaded Touchtest.zip which is a very bad Unity app which uses the plugin - seriously - it’s just an empty app which talks to the plugin and displays the touch info on screen. Tested on win7 and win8 desktop, although there are a million combinations of touch screen and OS / Driver etc. & so I haven’t tried them all, so its uploaded as-is; and I make no guarantees about running correctly. I also make no guarantees about the exe itself - I scanned it before uploading but - as always - scan before you run!”
