  • Improving the efficiency of Kinect for Windows DTWGestureRecognition Application

    - by Ray
    Currently I am using the DTWGestureRecognition open source tool for Kinect SDK v1.5. I have recorded a few gestures and use them to navigate through Windows 7. I also have implemented voice control for simple things such as opening PowerPoint, Chrome, etc. My main issue is that the application uses quite a bit of my CPU power which causes it to become slow. During gestures and voice commands, the CPU usage sometimes spikes to 80-90%, which causes the application to be unresponsive for a few seconds. I am running it on a 64 bit Windows 7 machine with an i5 processor and 8 GB of RAM. I was wondering if anyone with any experience using this tool or Kinect in general has made it more efficient and less performance hogging. Right now I removed sections which display the RGB video and the Depth video but even doing that did not make a big impact. Any help is appreciated, thanks!

  • ipad video format

    - by Mike
    When you use iTunes to sync your videos with the iPhone the videos are always saved with no more than 640 pixels wide, if I am not wrong. What about the iPad? What is the size of videos iTunes syncs with iPad? 1024x768? and what if the video has a dimension below 1024x768? Will it scale up? or will it keep the video at low res and scale when you play? thanks.

  • Mobile Java, shiny and new: Nokia Asha and Nokia SDK 2.0

    - by terrencebarr
    Nokia has announced a series of new S40 phones called “Asha” – mass-market devices with smart-phone features: Good-sized touch screens, 1 GHz processors, WiFi connectivity, social networking integration, and more. Prices starting around €60 retail. In case you don’t know, the S40 series is built on Java ME and has a huge deployed base in many parts of the world where price/performance is critical. Along with the new phones, Nokia is also making available the new Nokia SDK 2.0 for Java (beta), which enables developers to build rich Java applications with multi-touch, sensor support, an improved Maps API, and the Lightweight UI Toolkit (LWUIT) (more API & tools details). Furthermore, there is a host of developer information, the remote device access service, and even a porting guide to help you port your Android app to the new Asha platform. Last, but not least: More and better options to monetize your applications. Nokia has enabled in-app advertising and in-app purchasing, and improved the way applications can be discovered by customers. Nokia has seen downloads from the Nokia app store rise by 63%, now totaling billions. From what I’m hearing, the revenue opportunities on S40 for developers are often way better than what is typical for other smart-phone platforms (where competition is huge and consumers are fickle). Cheers, – Terrence Filed under: Mobile & Embedded Tagged: Asha Series, Java ME, Java ME SDK, Mobile Java, monetization, Nokia, S40

  • Suitable SDK to develop quick game?

    - by gRnt
    I'm currently undertaking a personal project at home that I need to turn around inside the next few months (which working full time and still learning programming makes it a tad difficult). I'm looking for suggestions on SDK's or tools (preferably free or that come with games, similar to steam tools) that I can use to develop a "game". I'm OK with coding but have no 3D development skills at all. I've very little experience with mod tools or SDK's at all but I'm hoping someone can point me in the direction of one that does the following: A decent library of prefab 3D models to build scenes. Ability to add scripting to the scene I've used Unity before and would prefer to continue to do so however I really have the worst 3D skills imaginable and can't waste time learning them. I'd be looking for pre-fab items that are both industrial and possibly more lush environments (trees etc). If it makes any difference (due to licencing and what-not) I WILL NOT be selling this game or marketing it in any way and I am a University Student if any places do educations licences. Another alternative would be to source free 3d models elsewhere but again while I'm still learning I have no idea where to look if someone could point me in the right direction I'll do the rest of the digging. Thanks

  • Switching VS2010 to use Windows 7.1 SDK

    - by freefallr
    I've used VS2008 on my development machine for some years now, with windows SDK v7.1. I've installed VS2010, and it's using the Windows SDK v7.0a, but I need it to use the Windows 7.1 SDK (which I had installed prior to installing VS2010). When I run the Windows SDK 7.1 configuration tool, to switch the Windows SDK in use, the tool updates for VS2008, but not for VS2010. The message it reports is: "The Windows SDK Configuration Tool has successfully set Windows SDK version v7.1 as the current version for Visual Studio 2008" The configuration tool is installed with the Windows 7.1 SDK and is found here: "C:\Program Files\Microsoft SDKs\Windows\v7.1\Setup\WindowsSdkVer.exe" VS2010 continues to use WSDK 7.0a, which extremely frustrating, as I need to do DirectShow development (so I need to build the baseclasses, which aren't released with 7.0a release of WSDK). Would I be correct in assuming that it's not updating VS2010 settings because VS2010 wasn't installed at the time that I installed Windows 7.1 SDK? Can I fix this manually, or should I uninstall Windows 7.1 SDK, then reinstall it? Any other suggestions / workarounds for this?

  • Corona SDK: Quality of support and resources?

    - by Nick Wiggill
    I've not used Corona SDK before and am looking into it for a friend. (He is also considering Unity.) I wonder what the support is like for Corona? While Unity has a great many customers and so the Unity team can often not address issues directly, the community at large is very helpful and there are many excellent resources: tutorials, forum posts, code resources. What is Corona like in this regard, and by comparison?

  • Font Anti-Aliasing on iPad SDK

    - by Felix Khazin
    I'm using a custom pixel font on the iPad SDK, and I'm trying to find a way to disable font anti-aliasing for UIFont. Pixel fonts usually work best when they don't have Anti-aliasing. I disable it easily in Photoshop when I create static resources, but this time I need a dynamic output with the custom font. Any ideas? Thanks.

  • How to switch versions of iPhone SDK?

    - by mobibob
    Now that I installed SDK 3.2 for my iPad development, I need to build with the previous version for my old iTouch. Is this possible to switch or do I have to uninstall 3.2, install 3.1.x and re-install 3.2 in a "versioned" folder?

  • Change/check minimum iPhone OS for Universal apps?

    - by Moshe
    The dropdown in XCode shows a base SDK of 3.2, but my iPod Touch (2nd generation), running OS 3.1.3, will run the app just fine in debug mode. (Command + Return/Enter) What is the actual base SDK of my iPhone/iPod touch version of the app and how can I change this? Changing it by right clicking on the project name in the "Groups and Files" pane and changing "Base SDK" under the "Build", doesn't do much. Edit: While writing this question, I found that scrolling down in "Build" and changing "iPhone OS Deployment Target" seems to be what I'm looking for, I'm posting this anyway. Perhaps someone has more insight into this...

  • Computer Visionaries 2014 Kinect Hackathon

    - by T
    Originally posted on: http://geekswithblogs.net/tburger/archive/2014/08/08/computer-visionaries-2014-kinect-hackathon.aspxA big thank you to Computer Vision Dallas and Microsoft for putting together the Computer Visionaries 2014 Kinect Hackathon that took place July 18th and 19th 2014.  Our team had a great time and learned a lot from the Kinect MVP's and Microsoft team.  The Dallas Entrepreneur Center was a fantastic venue. In total, 114 people showed up to form 15 teams. Burger ITS & Friends team members with Ben Lower:  Shawn Weisfeld, Teresa Burger, Robert Burger, Harold Pulcher, Taylor Woolley, Cori Drew (not pictured), and Katlyn Drew (not pictured) We arrived Friday after a long day of work/driving.  Originally, our idea was to make a learning game for kids.  It was intended to be multi-simultaneous players dragging and dropping tiles into a canvas area for kids around 5 years old. We quickly learned that we were limited to two simultaneous players. After working on the game for the rest of the evening and into the next morning we decided that a fast multi-player game with hand gestures was not going to happen without going beyond what was provided with the API. If we were going to have something to show, it was time to switch gears. The next idea on the table was the Photo Anywhere Kiosk. The user can use voice and hand gestures to pick a place they would like to be.  After the user says a place (or anything they want) and then the word "search", the app uses Bing to display a bunch of images for him/her to choose from. With the use of hand gesture (grab and slide to move back and forth and push/pull to select an image) the user can get the perfect image to pose with. I couldn't get a snippet with the hand but when a the app is in use, a hand shows up to cue the user to use their hand to control it's movement. Once they chose an image, we use the Kinect background removal feature to super impose the user on that image. When they are in the perfect position, they say "save" to save the image. Currently, the image is saved in the images folder on the users account but there are many possibilities such as emailing it, posting to social media, etc.. The competition was great and we were honored to be recognized for third place. Other related posts: http://jasongfox.com/computer-visionaries-2014-incredible-success/ A couple of us are continuing to work on the kid's game and are going to make it a Windows 8 multi-player game without Kinect functionality. Stay tuned for more updates.

  • iPhone SDK 3.2 and UIAppFonts

    - by tarmo
    I've added my custom font to UIAppFonts and it's loaded just fine: (shows up in [UIFont familyNames] ). When I manually set the font in viewDidLoad { [myLabel setFont: [UIFont fontWithName:@"CustomFont" size: 65.0]]; } everything works and the font is rendered. However doing the same thing in IB doesn't (some other default font is used instead). Having to create IBOutlets for each label and fixing up the fonts manually in viewDidLoad is pretty painful. Anyone else had problems getting the custom font support to work with 3.2 SDK and IB?

It might be easier but I not comfortable using a technique I dont feel that I understand "pretty" good atleast. So my question is: Anyone has any god tips on articles or books or any other type of resource that explains the API. Thanks in advance. /johan

  • Corona SDK (Lua) vs Native Obj-C for iPhone only word puzzle type game [closed]

    - by dodgy_coder
    I am trying to decide on whether to use the Corona SDK & Lua versus native Objective-C to develop an iOS app. This will be the first game on any smartphone I have developed and so its not that ambitious - a single player word puzzle type game - something sort of like scrabble. The advantages of Corona I can see are: Lua is probably easier to learn than Obj-C (shorter learning curve) meaning a possibly quicker development time Possibility to port to Android once its finished Advantages of native Obj-C are: Access to all and latest features of iOS More / faster available libraries Has anyone made this decision before? Are there any major advantages or disadvantages I've missed or got wrong here? Thanks.

  • Android performance/issues with Corona SDK?

    - by B5Fan74
    I know this is a fairly broad question. We are looking to develop a mobile game and want to use a multi-platform engine/SDK. We like what we see with Corona but in doing some reading, we are seeing a lot of references to poor performance on the 'droid platforms. I am unsure how much of this is still relevant? Many of the articles/posts/references/discussions vary in date from 18 months ago to earlier this year. Is there a reason we should not pursue Corona if Android support is important to us? The game is going to be 2D isometric view. Thanks!

  • Example to get Facebook Events using sdk v4 from fan page into Wordpress site [on hold]

    - by Dorshin
    Been trying to update to the new FB php sdk v4 for pulling events into my website, but having trouble finding how to do it. I want to pull public event information from a FB "page" using their fan page ID number. For example, a venue that has multiple events. What are the minimal classes I need to "require_once" and "use" to only pull the events (don't need to login)? The site is on Wordpress which doesn't use sessions, so what do I do with the "session_start()" statement? Will it work anyway? Could I get a basic code example of how to get the event info into an array? (I want to make sure I get the syntax correct) So far I've got the below code, but it is not working. session_start(); require_once( 'Facebook/GraphObject.php' ); require_once( 'Facebook/GraphSessionInfo.php' ); require_once( 'Facebook/FacebookSession.php' ); require_once( 'Facebook/FacebookCurl.php' ); require_once( 'Facebook/FacebookHttpable.php' ); require_once( 'Facebook/FacebookCurlHttpClient.php' ); require_once( 'Facebook/FacebookResponse.php' ); require_once( 'Facebook/FacebookSDKException.php' ); require_once( 'Facebook/FacebookRequestException.php' ); require_once( 'Facebook/FacebookAuthorizationException.php' ); require_once( 'Facebook/FacebookRequest.php' ); require_once( 'Facebook/FacebookRedirectLoginHelper.php' ); use Facebook\GraphSessionInfo; use Facebook\FacebookSession; use Facebook\FacebookCurl; use Facebook\FacebookHttpable; use Facebook\FacebookCurlHttpClient; use Facebook\FacebookResponse; use Facebook\FacebookAuthorizationException; use Facebook\FacebookRequestException; use Facebook\FacebookRequest; use Facebook\FacebookSDKException; use Facebook\FacebookRedirectLoginHelper; use Facebook\GraphObject; function facebook_event_function() { FacebookSession::setDefaultApplication('11111111111','00000000000000000'); /* make the API call */ $request = new FacebookRequest($session, '/{123456789}/events','GET'); $response = $request->execute(); $graphObject = $response->getGraphObject(); } So far, not getting anything in the $graphObject and it's throwing this error as well: PHP Fatal error: Uncaught exception 'Facebook\FacebookAuthorizationException' with message '(#803) Some of the aliases you requested do not exist: v2.0GET' in ../Facebook/FacebookRequestException.php:134 After I get something in the $graphObject, I want to add the info to a DB table. This part I am OK on. Thank you for the help.

  • help animating player in corona sdk

    - by andrew McCutchan
    working on a game in the corona sdk with lua and I need help so the player animates on the line drawn. Right now he animates at the beggining and the end but not on the line. here is the player code function spawnPlayerObject(xPlayerSpawn,yPlayerSpawn,richTurn) --spawns Rich where we need him. -- riches sprite sheet and all his inital spirites. We need to adjust this so that animations 3-6 are the only ones that animate when moving horizontally local richPlayer = sprite.newSpriteSet(richSheet1,1,6) sprite.add(richPlayer, "rich", 1,6,500,1) rich = sprite.newSprite(richPlayer) rich.x = xPlayerSpawn rich.y = yPlayerSpawn rich:scale(_W*0.0009, _W*0.0009) -- scale is used to adjust the size of the object. richDir = richTurn rich.rotation = richDir rich:prepare("rich") rich:play() physics.addBody( rich, "static", { friction=1, radius = 15 } ) -- needs a better physics body for collision detection. end and here is the code for the line function movePlayerOnLine(event) --for the original image replace all rich with player. if posCount ~= linePart then richDir = math.atan2(ractgangle_hit[posCount].y-rich.y,ractgangle_hit[posCount].x-rich.x)*180/math.pi playerSpeed = 5 rich.x = rich.x + math.cos(richDir*math.pi/180)*playerSpeed rich.y = rich.y + math.sin(richDir*math.pi/180)*playerSpeed if rich.x < ractgangle_hit[posCount].x+playerSpeed*10 and rich.x > ractgangle_hit[posCount].x-playerSpeed*10 then if rich.y < ractgangle_hit[posCount].y+playerSpeed*10 and rich.y > ractgangle_hit[posCount].y-playerSpeed*10 then posCount = posCount + 1 end end I don't think anything has changed recently but I have been getting an error when testing of " attempt to upvalue "rich" a nil value" on the second line, richDir = etc.

  • Kinect hacked for augmented reality
