Input Inactivity event
Dec 5^th, 2009, 8:06am

Hi there

Am trying to figure out how to implement inactivity as part of interaction.

Basically, after 3 seconds reset & display loop of visual static. Otherwise, if input detected within 3s keep on playing motion feature?

How would this be possible?

thanks

this code displays a main movie once button pressed & depressed plays static loop. I am aiming to keep movie playing if button continually pressed within 3s time, otherwise return to static. Not getting anywhere.

Code:


void draw(){
if (arduino.digitalRead(buttonPin) == 1){
  image(theMovie, 0, 0);
}
  else {
  image(theWhite, 0, 0);
}
theMovie.loop();
}

thanks for replying. I'm trying to implement what you're suggesting as:

the problem arises with the two counters counting the same. would it be possible to count individually - i.e on button push start counting?

Code:

void draw(){  
millis = second();
println(millis);
if (arduino.digitalRead(buttonPin) == 1){
  lastact = second();
 println("input" + lastact);
 if(millis - lastact > 3){println("pocahontas");}
  

// aim is to keep playing for 3 seconds after button push
  image(theMovie, 0, 0);

You are confusing the 2 functions millis() and second()
Code:


void draw(){  
    millis = millis();
    println(millis);
    if (arduino.digitalRead(buttonPin) == 1){
         lastact = millis();
         println("input" + lastact);
    }
    if(millis - lastact < 3000){println("pocahontas"); 
        // aim is to keep playing for 3 seconds after button push
        image(theMovie, 0, 0); 
    }
    else {
        // do something else after 3 seconds
    }
 }

I don't have an arduino to test it out but hopefully this will work.
