Tilt web components tilting accelerometer

Make Things

HTML elements such as images, sentences, and buttons will tilt if you tilt the acceleration sensor.

Software

Prepare two images, save them as “img1.jpg” and “img2.jpg“, and put them on the same folder with the code.

Input angles int the transform property of CSS to tilt HTML elements.

$("#img-1").css({ transform: "rotate(" + angle + "deg)" });
$("#button-1").css({ transform: "rotate(" + angle + "deg)" });
$("#sentence-1").css({ transform: "rotate(" + angle + "deg)" });

In this program, compare the first value and the current value of the acceleration sensor. Then, calculate the amount of tilt from the difference.

You can compare them with absolute values by using Math.abs()

if (Math.abs(currentAccelVals.y - initAccelVals.y) > 0.7) {
 //much tilt
} else if (Math.abs(currentAccelVals.y - initAccelVals.y) > 0.5) {
 //tilt
} else if (Math.abs(currentAccelVals.y - initAccelVals.y) > 0.3) {
 //little tilt
} else {
 //flat
}

Program

How to use

When you rotate the Y-axis like the image above, components of the web screen tilt following your movement.
