Linear scale is used in the showing the scale of a map or a chart. Some of them are engineer’s scale, linear encoder, linear scale, vernier scale and architect’s scale. It is interesting to note that there are several kinds of scales. It is limited in use whereas a ruler is unlimited in use. This is the reason why a ruler often contains calibrated lines that are employed in measuring distances.Ī scale on the other hand is simple kind of ruler that is used in geometry to measure length. Since it rules lines it is called as a ruler. It is important to know that a ruler is necessarily a straightedge to draw or rule lines. It is an instrument used often in geometry and engineering drawing. There is some difference between their connotations.Ī ruler is sometimes called as a rule or simply as line gauge. You can choose from four different units for length measurement: inches, feet, centimeters and meters.įor area, your measurements can be read in this units: square inches, square feet, square centimeters and square meters.Scale and Ruler are two words that are often confused as words that denote one and the same object.
(If you want to measure areas, keep adding points until you have your surface covered). Do it until you see yellow dots.Ģ) Yellow dots mean that surface is recognized.ģ) Place your first point using button ( + ).Ĥ) Move camera to the second spot and place another point. Numbers given by this app are accurate, just use it following these steps:ġ) Move your device from left to right. If you want to keep or save your measurements, you can keep a copy on your photos app. Thanks to AR, you can place or tag your measurements on any object, you could move around and continue with other objects, if you want to come back, all previous data will stay where you left them (only on active sessions). There is a wide variety of possibilities you can benefit from this Augmented Reality app: measure your living room, doors, frames, furniture, tv, monitors, even your own height. This means, you can use it for measurement of length, height, depth, width, and area. Measures length and surfaces between two or more points in a three dimensions ( 3D ) environment using the latest technology of Augmented Reality ( AR ). The attitudes of where you are and the measurement point are not set correctly. The measurement point is as high as the eye line.Ģ.
Please note that you can not measure correctly under the following conditions.ġ. Adjust the angle so that side of your iPhone/iPod touch (If device is the iPhone, it's the side with volume button) and the point of measurement (normally it is in same altitude as your place) are on a same line from your eye. Hold your iPhone/iPod touch with your left hand and turn it to the direction of the point of measurement. If they are equal, you do not have to change it from "0m". These are for adjusting the differences between the altitudes of your location and the point of measurement. You will see the items, "altitude of your location" and "altitude of measurement point" on the screen.
It measures distance with using triangulation system based on the level of your eyes calculated by your height and the tilt of your iPhone. Select "Measurement setup" to enter your height. "Air Ruler" is the application for iPone/iPod touch to measure distance with an accelearation sensor with ease.
