58 You actually need to check if the camera detects a face. Therefore you need an if-else-brick. In the condition of the brick insert the sensor value:** “is_face_detected”** which you find under the category: “devices” in the formula editor. So if your phone’s camera detects a face, your object should be shown, else insert a hide-brick in order to hide it.

71 Every time the camera is detecting a face, your object is shown on the screen. Now you need to add movement to the object so it stays on a certain part of your face. Pick the place at X: Y: – brick and insert into the x-position field the sensor value **“face_x_position” **which you find under “devices” in the formula editor. Into the y-value field insert **“face_y_position + 500” **since the object is a hat.

85 **5. Step**
86
87 For the last step you need to make sure that our hat adjusts according to your face size. If you are close to the camera you want a bigger hat, if you are further away a smaller one. Therefore add the set size to-brick and insert the sensor value** “face_size”**. Multiply this value with a certain number to fit your object to the correct size. In this case we choose to multiply it by 5 but you can try different values to get your perfect result.
