Intelligent Kiosk Sample
The Intelligent Kiosk Sample is a collection of demos showcasing workflows and experiences built on top of the Microsoft Cognitive Services. Most of the experiences are hands-free and autonomous, using the human faces in front of a web camera as the main form of input (thus the word "kiosk" in the name).
Requirements
- Windows 10 version 1809 or later (the sample is a UWP application).
- A webcam, ideally top-mounted so you have a similar experience as looking at a mirror when interacting with the demos
- Visual Studio 2019 with the Universal Windows Platform workload enabled
- API Keys
- Between the various demos, you might need API keys for Face, Computer Vision, Custom Vision, Text Analytics, Bing Search and Bing AutoSuggestion. Visit Microsoft.com/cognitive if you need keys. Please notice that some of the demos perform tasks in realtime, so if you are going to use some of those demos you will need to upgrade to a paid key so it has enough throughput and won't be throttled.
Running the sample
- Open the solution in Visual Studio 2019
- Right click on the IntelligentKioskSample project and set it as the StartUp Project
- Run the solution (F5)
- Enter your API Keys in the Settings page (they will be saved in the user profile). See Settings for more details on the available settings.
- If you prefer using command line to obtain the keys, you can follow the steps in the in the Key Acquisition Steps file on how to do that through azure cli commands from bash / git bash
- Explore one of the scenarios
If you have build issues on first launch, try to reload your project. Also make sure all NuGet packages are installed correctly.

Source Code Structure
1 Kiosk/ServiceHelpers: A portable library that serves as a wrapper around the several services.
- One of the key things that the wrappers provide is the ability to detect when the API calls return a call-rate-exceeded error and automatically retry the call (after some delay).
- The ImageAnalyzer class is another key class here, responsible for wrapping an image and exposing several methods and properties that act as a bridge to the Cognitive Services.
- Another example of functionality is the FaceListManager class, which is a wrapper on top of the FaceList APIs to make it easier to track unique faces.
2 Kiosk: The main version of the kiosk
- Kiosk/Views: The root pages that represent the various views in the kiosk.
- Kiosk/Controls: The controls used by the various pages in the kiosk.
