是否可以从 OS X 中的程序模拟鼠标的动作？具体来说，简短的版本是我正在尝试使用两个网络摄像头来模拟触摸屏。因此，假设我可以获得 X、Y 位置，我可以通过鼠标移动或单击将信息发送到操作系统吗？

编辑-或者如果在另一个操作系统中特别容易，我愿意考虑。

是的，有可能。您可以使用Quartz 事件服务来模拟输入事件。

假设 C，我写了这个简单的例子：

#include <ApplicationServices/ApplicationServices.h>
#include <unistd.h>

int main() {
    // Move to 200x200
    CGEventRef move1 = CGEventCreateMouseEvent(
        NULL, kCGEventMouseMoved,
        CGPointMake(200, 200),
        kCGMouseButtonLeft // ignored
    );
    // Move to 250x250
    CGEventRef move2 = CGEventCreateMouseEvent(
        NULL, kCGEventMouseMoved,
        CGPointMake(250, 250),
        kCGMouseButtonLeft // ignored
    );
    // Left button down at 250x250
    CGEventRef click1_down = CGEventCreateMouseEvent(
        NULL, kCGEventLeftMouseDown,
        CGPointMake(250, 250),
        kCGMouseButtonLeft
    );
    // Left button up at 250x250
    CGEventRef click1_up = CGEventCreateMouseEvent(
        NULL, kCGEventLeftMouseUp,
        CGPointMake(250, 250),
        kCGMouseButtonLeft
    );
    // Now, execute these events with an interval to make them noticeable
    CGEventPost(kCGHIDEventTap, move1);
    sleep(1);
    CGEventPost(kCGHIDEventTap, move2);
    sleep(1);
    CGEventPost(kCGHIDEventTap, click1_down);
    CGEventPost(kCGHIDEventTap, click1_up);
    // Release the events
    CFRelease(click1_up);
    CFRelease(click1_down);
    CFRelease(move2);
    CFRelease(move1);
        return 0;
}

并假设 GCC，编译：

gcc -o program program.c -Wall -framework ApplicationServices

享受魔法。

Swift鼠标移动并单击示例：

func mouseMoveAndClick(onPoint point: CGPoint) { 
    guard let moveEvent = CGEvent(mouseEventSource: nil, mouseType: .mouseMoved, mouseCursorPosition: point, mouseButton: .left) else {
        return
    }
    guard let downEvent = CGEvent(mouseEventSource: nil, mouseType: .leftMouseDown, mouseCursorPosition: point, mouseButton: .left) else {
        return
    }
    guard let upEvent = CGEvent(mouseEventSource: nil, mouseType: .leftMouseUp, mouseCursorPosition: point, mouseButton: .left) else {
        return
    }
    moveEvent.post(tap: CGEventTapLocation.cghidEventTap)
    downEvent.post(tap: CGEventTapLocation.cghidEventTap)
    upEvent.post(tap: CGEventTapLocation.cghidEventTap)
}

如果您不想编译并正在寻找基于 shell 的工具，Cliclick可能是解决方案。

这是一个基于 jweyrick 答案的工作 C 程序：

// Compile instructions:
//
// gcc -o click click.c -Wall -framework ApplicationServices

#include <ApplicationServices/ApplicationServices.h>
#include <unistd.h>

int main(int argc, char *argv[]) {
  int x = 0, y = 0, n = 1;
  float duration = 0.1;

  if (argc < 3) {
    printf("USAGE: click X Y [N] [DURATION]\n");
    exit(1);
  }

  x = atoi(argv[1]);
  y = atoi(argv[2]);

  if (argc >= 4) {
    n = atoi(argv[3]);
  }

  if (argc >= 5) {
    duration = atof(argv[4]);
  }

  CGEventRef click_down = CGEventCreateMouseEvent(
    NULL, kCGEventLeftMouseDown,
    CGPointMake(x, y),
    kCGMouseButtonLeft
  );

  CGEventRef click_up = CGEventCreateMouseEvent(
    NULL, kCGEventLeftMouseUp,
    CGPointMake(x, y),
    kCGMouseButtonLeft
  );

  // Now, execute these events with an interval to make them noticeable
  for (int i = 0; i < n; i++) {
    CGEventPost(kCGHIDEventTap, click_down);
    sleep(duration);
    CGEventPost(kCGHIDEventTap, click_up);
    sleep(duration);
  }

  // Release the events
  CFRelease(click_down);
  CFRelease(click_up);

  return 0;
}
