JOURNAL 1: KINECT VS KINECT 2.0

Terra(1161100234)

What is kinect&kinect 2.0?

Kinect is:

 - produced by: 
      Microsoft for Xbox 360 and Xbox One video game consoles and Microsoft Windows PCs
 - a motion sensing input devices
 - enables users to control and interact with their consoles/computer without any intermediary devices
 - such as: controllers
 - through a Natural User Interface (NUI), using gestures, spoken commands, body movement
 - uses an RGB camera with depth sensor and infrared projector with a monochrome CMOS sensor
 - which sees the environment not as a flat image, but as dots arranged in a 3D environment.

Difference between kinect and kinect 2.0?

• Kinect v1 is more lightweight and easy to carry and to install.
• there are more problems if use multiple Kinect v1, since they interfere a lot with each other.
• Kinect v1 interfere because they calculate depth using a IR light pattern projection, while Kinect v2 do not because they use another way to compute depth: time-of-flight.
• With Kinect v1 you can connect up to 4 to the same PC, you can use more Kinect v2 together but you can't connect them to the same PC.
• Kincet v2 seems a more refined version of Kinect v1- it is bigger and has a lots of cables and power converters.
• increase in resolution has been impressive, with the v2 reaching the full-HD resolution.
• Kinect v2 tracks more people, with more joints, faster and with greater precision.
• By using webcam&camera, Kinect v2 has much better field of view, color and resolution than the old one, new kinect has much sharper edges, less fuzzy and more precise and detail.
• In old kinect sensor, there is a lot of noise and it's not as precise as Kinect v2.

How to interact with kinect &kinect 2.0?

One of the example of using kinect:

Use kinect with the Xbox 360 dashboard. 

• You can use kinect to control the Xbox 360 using both your voice and gestures. 
• Make sure to have the latest console software.

Use gestures with the Xbox Dashboard

• hold your arm straight out to the side and bend your albow upward
• wave to kinect with your hand by moving your forearm left and right 
• once you wave at the Xbox Dashboard, a hand cursor appears
• You can now use gestures to navigate the dashboard instead of a controller

Use voice commands with the Xbox dashboard

• when you're at the Xbox dashboard, say 'Xbox'.
• the kinect speech bar opens
• you can now say any of the words that appear on the screen
• for ex: say " Xbox Social" to move the Social area of the daashboard

1) Kinetic projector: touch screen

• based on the video as example:
• the video demonstrates of how the program detect the projected screen, hand position and distance
• all you need is a projector and a kinect to have your own interactive wall
• 
  

• the kinect sees how it is being projected, and then the software will interpret what is the shape of the surface, were they displace and how big is the displace
• once it knows that, it also detects where your fingers are...

Kinect's ability are also being used extensively in performing arts and contemporary dance.

2) Interactive Dance Performance with Kinect

• based on the video as example:
• a performance that associates a dancer's body with visuals to produce a digitized physical choreography
• plays on perspective and depth perception to showcase the movement of the dancer's body
• interactive digital content and software dance show was developed by We Dream
• motion tracking algorithm, creates visuals based on projective coordinates of each dancer on XYZ plane.
• The software development finished in 10 days and debugged in 2 days
• Setup uses a Kinect™ Sensor, 8000 Lumen projector. 
• it was organized by Bilgi University Students
