Which to choose? ALL
Microsoft Kinect Issues:
 The device is large
 A dedicated power cord is required
 The amount of data generated by the sensor
also tends to saturate a USB controller
 Kinect cannot easily distinguish individual
fingers on a hand
 Most of the features listed above require the
Microsoft SDK, which is only supported for
desktop applications on Windows 7 and 8.
Microsoft Kinect Advantages:
 Skeletal tracking
 Face tracking
 Multiple sensors:
 Raw data
 Voice control
Best for:
Kiosks, installations, and digital signage projects where the user will be
standing fairly far away from the display.

33. #CDays14 – Milano 25, 26 e 27 Febbraio 2014
Which to choose? ALL
Leap Motion Issues:
 Sensing range is fairly
limited.
 Only fingers are tracked.
 There is no skeleton or face
tracking.
 No access to the raw sensor
data.
Leap Motion Advantages:
 Finger tracking is fast and
accurate.
 Smaller and less expensive
 Framework support: .NET,
Processing, Cinder, etc.
 Compatible: Mac OS and
Windows.
Best for:
Controlled kiosk environments with a pointing-based UI.
Generally best for general audience desktop apps which can be distributed in the
Airspace store.

34. #CDays14 – Milano 25, 26 e 27 Febbraio 2014
Which to choose? ALL
Intel Issues:
• Getting some of the deeper features (like
age and gender detection) to work is a
bit tricky.
• Device and software are in beta.
• Due to the close range of the tracking
system, hand gestures must be designed
such that a user’s hand doesn’t occlude
their own view of the display.
Intel Advantages:
 Smaller and less expensive
 Close-range tracking
 Hand posture/gesture recognition
 Facial analysis
 Speech (built-in support for
speech synthesis powered
by Nuance).
 Raw data
 Framework support: Processing,
Unity and OpenFrameworks
Best for:
Desktop/laptop applications where the user will be seated in front of the PC.
Close range applications where features, apart from hand tracking and recognition, are
necessary without too much precision or accuracy.
