Public speaking requires that you give your audience — and your presentation topic — your full, undivided attention. If you’re constantly tinkering with your laptop, tablet or smartphone to change slides or other visuals, you might lose your audience. That’s where a laser pointer comes in.

Laser Pointer Buying Guide

The best laser pointers don’t just help you point out different parts of your presentation. They also serve as wireless controls. Many of the best laser pointers can also be used to control the volume of your presentation’s media, as well as switch between slides and viewing modes.

When you’re shopping for the best laser pointer to use in a professional setting, it’s important that the laser pointer is compatible with the device you’re using. Often, laser pointers are built to work with both Apple and Windows products.

Are you using Laser Pointer in PowerPoint? 6 Reasons Why You Should

Presenting can be stressful at the best of times. Add to that the stresses of being hunched over your laptop, speaking into your screen, losing your audience, and suddenly even the best PowerPoint slides show can seem confusing and disengaging.

That is why tools like laser pointers come in handy. A laser pointer offers many benefits that turn a forgettable presentation into a memorable one.

This article will discuss the main benefits of using a laser pointer for your presentation and how to use the mouse pointer feature within PowerPoint.

FAQs:

Are laser pointers good for presentations?

Laser pointers add a lot of value to a slide show. A PowerPoint presentation can have many moving parts and plenty of information on each PowerPoint slide.

Using pointer movements, a laser pointer allows you to highlight which aspects of the current slide you want your audience to focus on.

What is a “mouse pointer” in a slide show?

The laser pointer feature within PowerPoint allows your mouse to become a built-in laser pointer. You can turn your mouse into a laser to highlight critical points within your presentation.

How do you use a laser pointer in Microsoft PowerPoint?

Select the From Beginning or Current Slide button on the Slide Show tab.
Hold the Ctrl key and click and drag the left mouse button to use it as a pointer.

A mouse pointer is an excellent alternative for your slide show if you do not own a laser pointer.

How do you use a laser pointer in Microsoft PowerPoint on iPad?

To highlight a particular aspect of your slide show on iPad, tap and hold your finger to activate the laser pointer. A red circle will pop up, which is the laser pointer icon. You may need to retry if you do not see the red laser pointer color.

6 Reasons Why You Should be Using a Laser Pointer.

It Gives You More Control.

One of the main benefits of using a mouse or laser pointer for your PowerPoint presentation is the control it provides you with.

If you use the mouse pointer option, you control aspects of your slide show your audience focuses on. When the mouse pointer appears, views get drawn to it and follow it around the slide show tab.

You have even more control if you use a laser pointer with a clicker. You can move freely without hunching over your laptop as you present.

Once set up in slide show mode, you can move away from your laptop and use the laser pointer to highlight important aspects of your current slide, move to the next slide, execute perfect slide timings, and take your audience through your entire PowerPoint slide show.

It Benefits the Viewer.

Not only does a pointer benefit you, but it also benefits your audience. When the mouse pointer appears and the laser pointer movements begin, your audience has an easy-to-follow guide, allowing them to digest the information as you intended.

Without a laser pointer feature, showing off specific aspects of a slide show tab with just your left mouse button can be challenging.

The sharp laser pointer color makes it clear to your audience which part of the slide show they should focus on, such as a particular image or dialog box.

Even if you submit a recorded slide show, using a mouse pointer after selecting “record slide show” will help your digital audience follow each slide as you intended.

Any slide show recording that has turned the mouse into a laser is much easier to follow than a slide show without. Combine that with the perfect PowerPoint design, and you’re on to a winner.

It Allows You to Move Around While Speaking.

As I have briefly touched on, a laser pointer gives you the power to move around while conducting your slide show. This benefit may not seem like a big deal initially, but having the freedom to walk around and command attention while delivering your slide show can be highly beneficial.

If you present to people you have not worked with before, you want to leave them with a lasting impression. When you are in slide show mode, sitting behind your laptop, clicking buttons, it makes your presentation much easier to forget.

However, you instantly become much more memorable if you are front and center, addressing your audience with your presentation in the background.

If you want to ensure your PowerPoint slide show is as impressive as you’re presenting,

It Helps Build Confidence.

Using a laser pointer for your slide show also helps you become more confident in your presentation.

Knowing you can use a laser pointer to ensure your audience sees particular images or a particular dialog box in the order you planned instantly gives you more confidence that your presentation will succeed.

This additional confidence will flow into your presenting style, making the presentation even better.

It Shows Professionalism.

Using a laser pointer highlights your professionalism. Think back to any time you have seen a presentation that has used a laser pointer or a mouse cursor as a laser. Were they high-quality, professional presentations?

I would anticipate that 99% of the answers to that question were yes.

A laser pointer is an excellent option to ensure you seem professional when delivering your presentation.

It Helps Your Presentation Stand Out.

Finally, a laser pointer helps your presentation stand out from the crowd. If your presentation is one of many on that particular subject, a great way to ensure that your presentation stands out is to use a laser pointer.

Want to highlight specific information you have included on a current slide? A laser pointer will help your audience remember specific facts and figures that you highlight within your presentation.

This tool could give you the edge against your competitors and ensure you are front of mind when your audience reviews each presentation they have seen.

Main
operations involving pointers

Assignment
is a two-place operation, both
whose operand is pointers. As for
other types, assignment operation
copies the value of one pointer to
the other, as a result both pointers will be
contain the same memory address.
If both pointers involved in
assignment operations are typed,
then both must point to objects
of the same type.

arithmetic, which are described below.

TO
you can add an integer to the pointer
or subtract an integer from it. Because the
memory has a linear structure,
adding a number to the address will give us

number of bytes (or other units)

subtract one pointer from another (both

have the same type). The result of such
subtraction will be of type integer
with sign. Its meaning is shown in
how many bytes (or other units)
one address is separated from another in memory.

Note
pointer addition doesn’t make sense.
Since the program is being developed
at relative addresses and at different

different areas of memory, the sum of two
addresses in the program will give different
results for different runs.
Offset of the same objects within the program
relative to each other does not depend on

will be constant, and such an operation

Operations
address arithmetic is only performed
over typed pointers.
Unit of measure in address arithmetic
is the size of the object, which
is addressed by the pointer. So if
the ipt variable is defined as a pointer
to an integer (int *ipt), then the expression ipt+1
will give an address greater not by 1, but by the number
bytes in an integer (in MS DOS – 2). Subtraction
pointers also results in no
the number of bytes, and the number of objects
of this type that fit in memory
between two addresses. This is true
both for pointers to simple types, so
and for pointers to complex objects,
whose dimensions are tens,
hundreds or more bytes.

IN
connections with extended C language

mention the different views
pointers in this language. In C, pointers
of any type can be near and
distant (far) or (huge). This differentiation

Near pointers are

pointers are represented by two

C++ | What are pointers? Like references, pointers are used to access an object indirectly. However, unlike references, pointers
have great potential.

Defining a pointer

To define a pointer, you must specify the type of the object pointed to by the pointer and the asterisk symbol *:

 data_type* pointer_name;

First comes the data type pointed to by the pointer, followed by the asterisk *. Then the name of the pointer.

For example, let’s define a pointer to an object of type int:

 int* p;

Such a pointer can only store the address of an int type variable, but so far this pointer does not refer to any object and stores a random value. We can even try to output it to the console:

#include 

int main()
{
    int*p;
    std::cout << p << std::endl;
}

For example, in my case, the console printed "0x8" - some address in hexadecimal format (hexadecimal is usually used to represent addresses in memory). But it is also possible to initialize the pointer with some value:

int*p{};

Since no specific value is specified, the pointer takes the value 0 as its value. This value represents a special address that does not point to anything.
You can also explicitly initialize to zero, for example, using the special constant nullptr:

int*p{nullptr};

Although no one forbids not to initialize pointers. However, in the general case, it is recommended to initialize anyway, either with some specific value, or with zero, as above. So, for example,
a null value in the future will determine that the pointer does not point to any object.

It is worth noting that the position of the asterisk does not affect the definition of the pointer: it can be placed closer to the data type or to the variable name - both definitions will be equivalent:

int*p1{};
int *p2{};

It is also worth noting that the size of the pointer value (the stored address) is independent of the pointer type. It depends on the specific platform. On 32-bit platforms, the address size is
4 bytes, and on 64-bit - 8 bytes. For example:

#include 

int main()
{
    int *pint{};
    int *pdouble{};
    std::cout << "*pint size: " << sizeof(pint) << std::endl;
    std::cout << "*pdouble size: " << sizeof(pdouble) << std::endl;
}

In this case, two pointers to different types are defined - int and double. Variables of these types have different sizes - 4 and 8 bytes, respectively. But the sizes of pointer values
will be the same. In my case, on a 64-bit platform, the size of both pointers is 8 bytes.

Getting an address and the & operator

Using the & operator, you can get the address of some object, for example, the address of a variable. This address can then be assigned to a pointer::

int number {25};
int *pnumber {&number}; // pointer pnumber stores the address of the variable number

The expression &number returns the address of the variable number . So variable pnumber will store the address of variable number .
Importantly, the variable number is of type int, and the pointer that points to its address is also of type int. That is, there must be a match by type. However, you can also use
auto keyword:

int number {25};
auto *pnumber {&number}; // pointer pnumber stores the address of the variable number

If we try to print the address of the variable to the console, we will see that it represents a hexadecimal value:

#include 

int main()
{
    int number {25};
    int *pnumber {&number}; // pointer pnumber stores the address of the variable number
    std::cout << "number addr: " << pnumber << std::endl;
}

Console output of the program in my case:

number addr: 0x1543bffc74

In each individual case, the address may differ and may change with different launches of the program. For example, in my case, the machine address of the number variable is 0x1543bffc74 .
That is, in the computer's memory there is an address 0x1543bffc74, at which the number variable is located. Since the variable x is of type int,
then on most architectures it will occupy the next 4 bytes (on specific architectures, the memory size for the int type may differ). Thus,
a variable of int type will sequentially occupy memory cells with addresses 0x1543bffc74, 0x1543bffc75, 0x1543bffc76, 0x1543bffc77.

And the pnumber pointer will point to the address where the variable number is located, that is, to the address 0x1543bffc74.

So, the pnumber pointer stores the address of the number variable, but where is the pnumber pointer itself stored? To find out, we can also use the & operation on the pnumber variable:

#include 

int main()
{
    int number {25};
    int *pnumber {&number}; // pointer pnumber stores the address of the variable number
    std::cout << "number addr: " << pnumber << std::endl;
    std::cout << "pnumber addr: " << &pnumber << std::endl;
}
