Description
Interaction with Leap Motion <https://www.leapmotion.com/product/desktop>, based on the Web Socket API <https://developer.leapmotion.com/documentation/javascript/supplements/Leap_JSON.html>.
Here is a simple example applicaton that prints all events:
main :: IO ()
main =
runWithHandler def [setFocused True, setGestures True] $ event ->
print (event :: Event Float)
- data Configuration = Configuration {}
- data Version = Version {
- serviceVersion :: String
- version :: Int
- setBackground :: Bool -> ConnectionModifier
- setFocused :: Bool -> ConnectionModifier
- setGestures :: Bool -> ConnectionModifier
- setOptimizedHMD :: Bool -> ConnectionModifier
- type ClientApp a = Connection -> IO a
- type Handler a = Event a -> IO ()
- run :: Configuration -> ClientApp a -> IO a
- runWithHandler :: FromJSON a => Configuration -> [ConnectionModifier] -> Handler a -> IO ()
Configuration
data Configuration Source #
Configuration for a connection to a Leap Motion controller via Web Sockets.
