How it works
You may be surprised by SuperRuler for its interest and practicality. But what’s more exciting is that it can make the remote distance measurement possible. Let’s try!
The sketch above shows Mary, on the right, and she must know her height, which is the length FG. Focusing our line of sight on the top of Mary's head, the line is EF. By clicking the screen where our line of sight is focused, we get two points: A and B. AB gives the angle measurement of the line of sight. Similarly, we can get the angle measurement of the line of sight to Mary's feet. Lines AB and CD intersect at point E, creating triangle-EFG. We can now compute the height of the triangle which is what we need if you know the degree of the angle and the length of the bottom edge, because of its shape. By contraries, we can compute the height of Mary if we know that distance.
Configure the Data
Besides the options to measure height and distance, there is also the option to measure angles. Compute it either by connecting the 4 points which users click (choosing “Screen Measurement”), or by inputting the degrees of the angle between the top and the bottom of the target into the edit box (choosing “Manually input”).
Measurement View
When measuring, SuperRuler will beep if you click on the screen so that you know that you have touched the screen when you are focusing on the target instead of the screen. Practice data for reference: We have experimented to test the height of a refrigerator. The height of the refrigerator is 135cm, while the distance between the door and the refrigerator is 413cm. To avoid the error caused by the shaking of my hand, We put the PDA on a chair positioned at the door and then tested the distance between the door and the refrigerator, using the method introduced above. It’s amazing to achieve the result of 407cm, with the error of only 6cm!
Key Mapped in tree mode
In measurement mode, you may not click the right point the first time, the problem is solved by adding the function “key mapped” You can use the hardware Mail key to cancel the last point; and you can use the arrow key to move the last point.
