GestureWorks allows developers to create applications that support multiple, simultaneous gestures. It is the most robust multitouch authoring solution for Adobe Flash and Adobe Flex. It is also easy, saving countless hours of development time.
There are several multitouch gestures defined in on the GestureWorks website.

Artificial neural networks are computational models that simulate aspects of a biological neural network. As shown in Figure, artificial neural networks are built up as a collection of node layers:
- An input layer
- A series of hidden layers
- An output layer
The outputs between states are based on weights are learnt using back propagation through examples. The neural network does not generally perform as well as the more specialized Hidden Markov Models, but this approach has been used with some success in the recognition of sign language gestures in a paper demonstrating the use of size functions used an artificial neural network approach

A three dimensional gesture may be recognised and processed using a Hidden Markov Model, which is a simple dynamic Bayesian network. This spatiotemporal model, which is defined below, reduces the 3 dimensional complexity of the hand gesture into a two dimensional problem, and analyses and categorizes these gestures using a state machine. This model has been employed, with success, in speech and handwriting recognition.

In trigonometry and geometry, triangulation is the process of determining the location of a point by measuring angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly (trilateration). The point can then be fixed as the third point of a triangle with one known side and two known angles.

The Accord.NET library, built on top of the Aforge.NET library, is known for its statistical modelling capabilities. The discrete Hidden Markov Models present in the library provide the tools for the recognition of spatiotemporal gestures.

32feet.NET is a shared-source project to make personal area networking technologies such as Bluetooth, Infrared (IrDA) and more, easily accessible from .NET code. It supports desktop, mobile or embedded systems. The project currently consists of the following technologies:
- Bluetooth
- IrDA
- ObjectExchange

Iridium is the numerical foundation of Math.NET, aiming to provide commonly used mathematical elements for scientific numerical computations. It offers the infrastructure for basic numerics, linear algebra, random generators and distributions, integral transformations, etc. Iridium is self-contained, it does not depend on external libraries like Intel MKL, BLAS or LAPACK.

Nintendo's Wii Remote (forever known as the Wiimote) is a fantastic little controller for the Nintendo Wii system. Because it uses Bluetooth to communicate with the Wii, it can be connected to and used by practically any Bluetooth capable device.
C#, Wii • February 2009
Johnny Chung Lee has developed several applications that use the Nintendo Wii Remotes for interaction with a computer using a Bluetooth connection:
- Tracking Your Fingers with the Wiimote
- Low-Cost Multi-point Interactive Whiteboards Using the Wiimote
- Head Tracking for Desktop VR Displays using the Wii Remote
The projects developed are built using the WiimoteLib library.

In an alternative Universe, this is what the Nintendo Wii's Wiimote and nunchuck would have looked like: this is the amazing transforming GyroPod, a motion-sensing gamepad prototype that Gyration made for Nintendo back in 2001.

A useful feature of delegates is the ability to execute a method asynchronously. That is, through a delegate, you can begin invocation of a method and then return immediately while the delegate executes its method in a separate thread.
