AUGMENTED REALITY IN MOBILE PHONE...

What is an augmented reality software in mobile phones?

AR Core technology can do several things, for example it can track location of a phone and the direction in which it is facing, it can be achieved by using the camera and sensors.  Generally, we use to call the same app as AR Core in Android phones and AR Kit is used for iOS.  Generally, AR Core is a developer tool, which helps completely reality experience.

AR Core primarily concentrates main importantly on three areas: 1) motion tracking 2) understanding the environment 3) estimating the light.

For example, when we are playing games, real world pictures can't be inserted and merged with virtual pictures.  Virtual objects are directly linked with real world objects and one can feel that the virtual objects are really present there, Suppse, if we have a table, we take a photograph of it, and all the virtual objects can be supposed to be placed on it, when we observe these combinations, we feel that the table consists of all the things,

The environmental understanding feature enables that there is a physical connection between virtual objects and real world.  The motion tracking feature makes to interact with virtual things. The estimating light feature allows to feel a realistic looking objects, there is an adjustment between the real world environment lighting and virtual things.

simple microscope

SIMPLE MICROSCOPE

                   Dissecting microscope is another name for simple microscope.  It is very important laboratory equipment, it is often used in biology experiments.  While we are using simple microscope, one should follow these precautions.

1. When we are taking out the microscope for the experiment from its case, one should use both hands 

2. Proper maintenance should be taken that is this microscope should be kept in case when not in use.

3. There are two mirrors used in it, one is plane mirror and it is used for natural day light and another mirror concave mirror for artificial light.

Different parts of the microscope:

- Basal iron foot

- for holding the eye piece a short limb is used, for focussing an adjustment screw is used

- to keep the slide, there is a glass stage.

- Plano-concave mirror is used for light adjustment.

PROCEDURE TO USE THE MICROSCOPE:


             Main aim of the apparatus is to view the object to be examined, clearly.  Take the object or material to be examined on the glass stage, add a drop of glycerin, cover with a cover slip, adjust the mirror for light and then view the object or material through eye piece.

types of eye defects

HUMAN EYE AND COLOURFUL WORLD:

Introduction:


                    Light is the primary source of vision.  When light incidents on any object, it gets reflected into our eye, then the sensation of vision takes place by human brain.  The light rays coming from the object forms image on our retina, it is inverted one.  But, the brain makes us to see erected form.

General questions while observing any object.......


Q1. How do we see an object?

Q2. What is the least distance of distinct vision?

Q3. What is the angle of vision?

Q4. When do we feel the object or the text, is not visible properly?

Q5. How many types of defects are there?

Q6. What is the construction of eye?


Q7. Is there any lens present in our eye?

Q8. Which is supposed as a screen in our eye?

Q9. How the light rays get refracted into our eye?

Q10. Explain clearly the defect arises with our age?



Activity 1: Let us take a textbook, and make the book very close to our eyes, then think whether the text is visible properly or not.   Move the book a little distance and observe the letters in book, then as the distance is increased the visibility is increased.  The minimum distance where we can read the text clearly, is called 'the least distance of distinct vision'.  It is approximately 25cm.  This distance may be less in younger children.

Activity 2: Imagine that an aeroplane is flying in air.  How do we think the size of the aeroplane.  It appears very small, as the distance from us is increased.  The reason is that the angle made with our eye is very small, the angle made by the two rays coming from the aeroplane.  In this way, we can understand that when the angle made with our eye is more than 60 degree, then we can't see an object completely.  When this angle is smaller than 60 degee, then we can see completely.  This angle is called angle of vision.


Activity 3: The people who are unable to see the objects which are very nearer or who can see the distant objects is called the eye defect hypermetropia or hyperopia.  In this case, the rays coming from nearer objects are focussed beyond the retina.  To minimise this defect or eradicate it, we need a biconvex lens.  The lens makes all the rays to concentrate on retina.

Activity 4: The people who are unable to see the objects which are very distant or who can see nearer objects, then the defect is called myopia.  In this case, the rays coming from the distant objects can be focussed before the retina.  To correct it, we must use biconcave lens in our spectacles.  The lens makes to focus on retina.

MIRRORS and THEIR TYPES

Mirror can reflect the light due to its non transparency property...the surface where light reflects is called reflecting surface.
CLASSIFICATION OF MIRRORS
1. Plane mirrors
2. Spherical mirrors


principles of reflection:
1. The angle of incidence is equal to the angle of reflection


2. Incident ray, reflected ray and Normal lie in the same plane. They are coplanar.
