MOUSEINPUT_TIMEOUT

Captures continuous mouse movements with timeout

Description

MOUSEINPUT_TIMEOUT returns continuous mouse locations with timeout

  OUT = MOUSEINPUT_TIMEOUT returns the sequence of mouse locations between a button press and a button release in the current axes. It does not timeout. OUT is an Nx2 matrix, where OUT(1,:) is the location at button press and OUT(END,:) is the location at button release.
 
  OUT = MOUSEINPUT_TIMEOUT(T) times out after a period of T seconds. T can be a fractional value (T=inf indicates no timeout). If the mouse-button has not been pressed during that time, OUT is []. If the timeout occurs during a mouse movement, OUT contains the mouse locations before the timeout.
  
  OUT = MOUSEINPUT_TIMEOUT(T,AH) records the mouse movement from the axes specified by axes handle AH.
   
Note: MOUSEINPUT_TIMEOUT differs from GINPUT in two ways.
(1) It does not return information about which mouse button was pressed,
(2) It ignores key presses.
 
-- Example:
% record movements from current axes
% (with timeout after 4.5 sec), and
% plot the final movement.
out = mouseinput_timeout(4.5, gca);
hold on;
plot(out(:,1),out(:,2),'r');
out(1,:) % location at button-press
out(end,:) % location at button-release

Dear Vallabha,

Code is excellent, thanks. But I'd like to ask something:

How can we acquire the mouse movements in real time by embedding your function to Simulink, or equivalently, is it possible to get real time mouse data?

[kakani young]

this code works perfectly! it allows me to use a pen tablet to extract curves directly from image files.

hi Vallabha
im working in online handwriting recognition.
that code is good. i can get (x,y)pts from pen online but the presure of the pen and time for every point i coudnt
can u adviceme
thanks

@UTM ali:

It is not possible to get the pressure value of the pen (since the code uses the mouse interface).

You can get the time for every point by a small tweak to the code. At the start of the function get the current time:
    startTime = tic;
and change lines 89 and 99 to:
    selectedPts(end+1,:) = [pt(1,1:2) toc(startTime)];
