INTRODUCTION
Lab Camera is a web camera based natural science exploration and data logging laboratory that allows
students and teachers to carry out substantial scientific observations and measurements, using a computer
and the software.
The software has currently seven functions all of them are very easy to use. Students can use it in class or
even to solve their homework, but it also encourages independent experiments that can be carried out
effectively, giving further boosts to Science based subjects. Lab Camera arouses curiosity about the
surrounding world around you and it ignites creativity in how you explore it.
This User Guide provides an overview of the components and all features of LabCam.
Enjoy experimenting!
GENERAL INFORMATION
Protect the environment & yourself
Please do not harm any animals, plants, or the surrounding environment when you carry out experiments
with LabCam. Experiment responsibly and carefully for your own safety. Lab Camera takes no
responsibility for any damages that might occur during your use of the software. While we are confident
that Lab Camera is one of the safest ways to undertake science experiments, please enjoy the software at
your own risk!

TIME LAPSE
The Time Lapse function helps you observe and better understand the slow processes in nature, such as
the formation and migration of clouds, ice melting, the growth of plants, etc. The software makes still shots
in configurable intervals and stitches these images into a coherent stream of video.

Calibration
Calibration lets you measure objects in your camera view. If you know one dimension of the examined
object, you can use it as a reference to calibrate. In order to calibrate your camera view, place an object of
known size (eg. mechanical pencil refill lead) in front of the camera in the same plane where your target
object is located and tap the calibration button. You can also use our printable scale sheets available at
http://www.webcamlaboratory.com/downloads.php

UNIVERSAL LOGGER
Universal Logger is a very unique, real time, data recognition module that can register real-time readings of
any instrument that has digital, radial dial or liquid-in-glass display. All your obsolete measurement devices
in school that cannot be connected to a computer are made useful again.

When you press the Digital Display icon, a 3-cell grid will appear. Each cell represents one
digit on your device. In case you need more or less cells, use the +/- buttons on the top edge
of the grid. You can add cells to represent up to 6 digits. Each corner of the main grid is an
active corner. The circles on the bottom edge represent the decimal places. Tapping one of
them results in placing the decimal mark between the corresponding cells.

Drag this corner to rotate the grid.
c
Drag this corner to skew the cells in case you have a device with italic digits.

By dragging this corner you can enlarge/reduce the grid to accommodate all digits on the
display.
Observe the recognized value and make sure it matches the actual readings of your
measurement device.

Set the minimum and maximum values of your measurement range.
4
Set the probe interval to desired value. For slow changes the probe interval can be longer. In
case of faster changes a shorter interval is recommended to obtain a smooth diagram.
5
Press the bin icon to delete the selected template.
The goal is to align the grid with the display in such a way that each cell covers one digit and the decimal
mark is in the same place as on the device. NOTE: reflection of light and insufficient lighting may affect the
accuracy of readings.

GRAPH CHALLENGE
Play with curves and learn representation of movement in a coordinate system using Graph Challenge. All
you need to do is pick a curve and select an object. Next, move the selected object or your mobile device
around to match your curve as close as you can.
The goal is to move an object in such way that it's movement curve overlaps the predefined curve as much
as possible. The software calculates the score in percentage of matching and saves it in the score list.
You can chose from horizontal, vertical, closer-further or rotation modes.
Object Tracking
You can use any colored object or a predefined marker with Graph Challenge. If you choose to track a
colored object, please make sure that this color does't occur in the background of the object. NOTE:
Rotation matching is only available when using predefined marker.
You can print the marker from the pdf file located in your Graph Challenge folder or use the image from the
appendix at the bottom of this manual.
In order to select a custom (colored) object for tracking, press the object on your camera screen. A colored
bounding box around the object will indicate a successful selection.
If you want to use the predefined marker for tracking, all you need to do is to bring the marker into the
camera's viewport. It gets recognized automatically and you can start calibration or matching the curve right
away. NOTE: when holding the marker, make sure that the whole marker is visible - don't cover the black
frame with your fingers.
Movement Control
There are two ways to move your object around in the camera view:
- you can either move the object in front of a steady camera, or
- move your camera in front of a steady object.

Size And Distance Calibration
To make sure that the y-axis of your diagram shows proper values, you will need to calibrate your object's
size and / or distance from the camera.

Press to start size and distance calibration wizard. The wizard will guide you through the
calibration steps.
Movement Area Calibration
After selecting an object for tracking, you will need to calibrate your movement area to make sure that the
object's movement can reach highest and lowest values of your curve. Once calibrated, you can use Graph
Challenge as many times as you want provided that the placement of your camera and the tracked object
is the same as during calibration.
When calibration starts, you will see a curve representing your object's movement in the right panel . Move
your object up-down, left-right, closer-further or rotate (depending on the chosen tracking mode) to register
the highest and lowest values your curve should accommodate to. After 5 seconds the calibration will stop
if there were two clear endpoints registered.
