TouchInjector

Hello world, Today I proudly present: TouchInjector TouchInjector is a Windows 8 Desktop application that translates TUIO into Windows Touch messages. It’s lightweight, easy to use and does not get in the way. No installation is required and with one click you can customize it to autorun with the system (on logon). As I frequently change my display settings, TouchInjector observes them and reacts accordingly. You can download it here. There are no further software requirements than a Windows 8 system. Just unzip, unblock and run it. (Allow access through the firewall and make sure that no other TUIO clients block the port.) Have fun! ~theCake

Q&A App

Hey, When my professor put a machine-readable quiz on his website, I made an app for my Phone to do the quiz.. Today I ported it to the desktop and I’d like to share it: Download Q&A App.zip It requires .NET Framework 4.0. To feed it with questions, you need a text file (preferable in UTF-8 encoding) that follows these simple rules: question-answer blocks are separated by one empty line question-lines begin with ‘Q: ’ answer-lines begin with ‘A: ‘ category-lines begin with ‘C: ‘ multiple Q/A/C-lines per block are allowed There’s a sample file in the *.zip. You can load a file from your computer, or from a remote location (eg. a textfile in a public dropbox folder). have fun!

Sync specific Folders with SkyDrive

Some of you may know, that I’m a huge fan of Dropbox, Windows Live Mesh and SkyDrive alltogether. Each of them has some exclusive features that I find most useful. This is the public sharing using a single URL of Dropbox, the cross-platform Features of SkyDrive (WP7…) and the feature to ‘select and sync’ any folder on your hard drive with Windows Live Mesh (in contrast to the quite unflexible syncing of just one folder). Well today on reddit, I came across a link to a blogpost… This guy, Jan Hannemann, had a genious idea: In the NTFS file system you can hard-link folders in a way that and application (such as Windows Explorer, or Windows Live Mesh) thinks that the folder is really there. These links are called folder-junctions and can be created using the command line. Fortunately he created an extension to the Explorers context menu that lets you do this in just two…

KinDrive (for Kinect for Windows SDK 1.0)

Recently I migrated from Beta2 to Kinect for Windows SDK 1.0, so here’s a quick review of the new features: works w/ Kinect for Windows hardware AND the ‘old’ Kinect for XBox360 requires Kinect for Windows SDK 1.0 (or at least its runtime) tracks two players (you can play split-screen-games…) sends not only WASD keys, but also UHJK racing-mode only, no detection of additional gestures! (like the ones in the older versions) you can use the DLLs to write your own interface (and detect more gestures) –> mail me, or comment if you have questions Oh and one random thought: I think the delay you feel when playing a game with it, is due to the slowness of your hands rather than b/c of software-delay – it’s just a theory I can’t prove, but compare it with playing w/ a hardware steering wheel… Here’s the download link

Kinect over Sockets

There’s no Kinect support in Windows 8 Metro, so I had to come up with a network-based solution to use the tracked skeleton data. A byproduct of this are the TCD.Networking and TCD.Kinect namespaces. Both have a Server and a Client child namespace (with simple network communication or Kinect over network..). What I can make available today is a sample of how to send Kinect-skeleton-data from a WPF server application through the network (or to localhost..) to a WPF client application. While an advantage of network-based routing is that you can have multiple clients, a major disadvantage is that you can’t use the tracking-engines methods to render 3D-coordinates to a pixel coordinate. I had to make a CustomSkeletonData class as well, b/c the JSON deserialization is kind of fussy. You may use all code and libraries you find in the solution to power your own projects =) Most of it…

KinDrive enhanced – working w/ every game using DirectX input

Last week – on thursday to be precise – I stumbled over a library to send input to the system on DirectX-level, called InputManager (a big different to all the tons of SendKeys()-wrappers out there!!). So great thanks to Shay from Israel for making this awesome library!! As all the rest of the architechture was up and running already, I just made a simple WPF application to show the Skeleton and listen for a gesture as well. The gesture (streching your arms in the air) causes the WASD-input to halt, a press of the F-Key (which I usually use to enter vehicles/use weapons in games..) and finally after 3.5 seconds everything continues as before. Here’s a video of the KinDrive for GTA WPF application: Then of course: GTA IV: And just for fun – Need For Speed Carbon: For those interested in DirectX-level Keyboard/Mouse input: I’ll blog about the InputManager anytime soon. My plan is to open source…

WikiSearch – a quick and dirty Windows 8 Metro App

I’ve been playing around with Windows 8 Metro development the last months and one day I did a quick Wikipedia App that integrates into the Search. The first version took me – no joke – less than 20 minutes, cause it’s just so easy! All you have to do to integrate into the search is to add this method to your App.xaml.cs: protected override void OnSearchActivated(SearchActivatedEventArgs args) { base.OnSearchActivated(args); if (mainPage == null) mainPage = new MainPage(); Window.Current.Content = mainPage; mainPage.OpenWiki(args.QueryText); Window.Current.Activate(); } After that go into Package.appxmanifest, switch to the Declarations tab and add a ‘Search’ declaration. mainPage.OpenWiki() would be a method that composes a Wikipedia-Search-URL from the queryText and tells a WebView to navigate to it. (webView.Source = new Uri(“http://en.wikipedia.org/w/index.php?title=Special%3ASearch&search=” + “queryString”);) I won’t go into any more detail at this point, but that is all the magic you have to do. Today I added multiple-language support to…

KinDrive

Hey everyone, I’m happy to announce that I finally did the re-coding of KinDriver, now called KinDrive. The new version is made with the Beta 2 SDK, is a lot more stable, simpler and faster than the old one. It lacks of speech recognition and remote-controlability, but I splitted the two main features (tracking and keypressing) into separate assemblies, so it’s very easy to build a whole new application out of it! Here comes the code part: (if you aren’t interested in using coding, skip to the last paragraph)   TCD.KinDrive.Tracking.dll In this assembly there are three classes: KinDriveTracker, Point3D and DriveInformation TCD.Mathematics.Point3D is just a helper class for 3D vectors/points with some useful calculation-methods (like calculating the distance etc.) DriveInformation exposes two properties, Throttle and Steer, as well as a constructor that takes a SkeletonFrame as a parameter. Tracking and steer/throttle calculations are done by this very same constructor….

Tool collection

Hey everyone out there, I just decided to share some tools I made with C# (Console or WPF) with you: 1. Batch4sqQR – A tool to create nice QR-Stickers for one or more Foursquare venues (download) 2. MergeTool – A tool to merge all *.gpx files in a folder into one new *.gpx (download) 3. AnonymizeTool – A tool to randomly shift the timestamps of all trackpoints & waypoints in all *.gpx files in a folder (download)   These tools are very simple, but there aren’t any or many applications on the internet that do those things^^ Of course you can contact me if you have any questions or so x)
