Toolkits: TouchID Toolkit

General Information

The TouchID Toolkit enables developers to create applications on the Microsoft Surface that can identify different parts of the hand, hands and users. Additionally, custom postures and gestures can be integrated easily.

Basis is the Fiduciary Glove. It consists of an ordinary glove with fiduciary tags stuck onto 15 key hand parts. The Microsoft Surface is able to recognize these tags very reliably. The TouchID Toolkit offers high-level access to the hand parts, glove and users. Additionally, postures and gestures can be created, tested and integrated in applications.


Download and Installation

  1. Make sure that Visual Studio 2010 Express or Professional is installed
  2. Install the Surface SDK
  3. Download TouchID Toolkit installer and execute
  4. To create a TouchID Application, create a new project in Visual Studio 2010 and use the template provided.
