|Free Group Video Conference with
Several Options in Apps and Devices
Many people have been using one of several possible Apps (such as LINE App or FaceTime or Zoom, or
Google Meet or Google Duo, or Skype, etc.) on one of several possible devices (such as iPhone, or iPad or
smartphone, or tablet or laptop PCs or desktop PCs) for one-to-One free video call. Many grand parents
have been using such App and device on free video call to see and to chat with their grand children thousands
of miles away.
With so many of us following government order of shelter-in-place to slow down the spreading of Coronavirus,
we are relying far more on free video-conference apps than we ever have. For example, the daily participants
in video meeting on the Zoom video platform surged rapidly from 10 million in December 2019 to 200 million in
These free video meeting Apps can be used on several kinds of device to participate in free group video
meeting for large number (100 to 200) of participants at different locations anywhere in the world, including
1.1. Devices for Video Meeting
The devices ready for such free group video meeting include iPhone, iPad, Android based smartphone,
Android based tablet, Facebook Portal and laptop PC. These devices have built-in camera and built-in
microphone and are ready for such group video meeting or group audio conference. Some samples can be
seen here, and here.
1.2. Desktop PCs Need a Webcam with Microphone
On the other hand, most desktop PCs have no built-in camera nor built-in microphone. If you want to use a
desktop PC for video meeting, you will need to buy a small webcam with microphone and USB connector and
to plug such webcam into the USB port of the desktop PC so that such enhanced desktop PC can handle
Some sample webcam with microphone and USB connector for desktop PCs can be seen and purchased on
the websites of Amazon, Walmart,Target, BestBuy etc.
It is seen that such small webcam with microphone and USB connector cost only about US$50 and can be
ordered/purchased easily from the websites of Amazon, Walmart, Target, BestBuy etc.
It is noted that the webcam for Windows PCs may be slightly different from those for Apple Mac PCs. Make
sure that you order the correct one for your Windows PC or for your Apple Mac PC.
With government lockdown order of Shelter-In-Place to slow down the spread of Coronavirus, many retail
stores have closed down, but many online stores are thriving with very efficient process for ordering and
delivering. It is now much easier and safer to get the webcam or many other products by ordering online
instead of going to a physical retail store.
The Coronavirus has very strong impacts on how human being are doing business and conducting various
meetings. This new way of business also creates a lot of new job opportunities for younger people to do the
shopping and delivery for older people who are in high risk group in this pandemic of Covid-19.
1.3. Benefits of Adding Webcam with Microphone To Your Desktop PCs
The benefits of adding such webcam with microphone to your desktop computer include not only ability to do
free video meeting with many other people all over the world, but also capability to do faster computer input by
voice as described on my website here.
You now have capability to see and to chat with your children or your grand children or your relatives or you
good friends thousands of miles away. You have capability to attend many interactive meetings of great
interest to you but are thousands of miles away. You can see your doctors more easily for medical problems
by video meeting.
The addition of microphone also enables you to operate your desktop PCs more conveniently by voice
command. You are no longer tied down to sit in front of your PC for hours. Your body now has more freedom
to stand up and to move around while using your PC with voice command. This is much better for your health.
1.4. Adjust Angle of Your Camera/Device and Lighting in Your Room
After you joined a video meeting, you may need to take a look of your video in the meeting and to adjust the
angle of your camera/device so that you are located well inside the window for other participants to see you
well. In other words, if your camera angle is not adjusted properly, other meeting participants may see only a
small piece of you, such as the top of your head, or may not see you at all.
1.5. Position of Light Source in Your Room
If the light source in your room is behind you, then you are back lighted in the video meeting. Your face and
your front side have no light such that you appear as a dark shadow in the video meeting. So, you need to
make sure that the light source in your room is in front of you shining on your face so that other participants in
the video meeting can see you well.
If the window behind you has strong lght coming from outside, then again you are back lighted and may
appear as a dark shadow in the video meetng. You need to close the curtain on the back window and to have
proper light source in front of you shining on your face so that other participant can see you well.
1.6. Hidden Icons of Microphone, Camera and Other Features of Video Meeting App on Small Screen
After you joined the video meeting successfully, the icons of your microphone, camera and other features of
video meeting App are often hidden on the small screen of iPhone or iPad, or Android smartphone or Android
tablet or even larger screens of PCs.
I guess that the reason that all these icons for various features of video meeting are often kept hidden during
most of meeting time is that the screen sizes of iPhones and Android smartphones are quite small. If all these
feature icons are displayed constantly during meeting time, these displayed icons will block substantial portion
of the contents of video meeting on the small screen and can be annoying. So, all these feature icons are kept
hidden until you need to access those features to do something such as muting or un-muting the microphone,
turning on or off the video camera, leaving the meeting, showing a PowerPoint presentation, or changing the
screen layout, etc. Then you use your finger tip to tap on the small screen to bring out these icons for you to
tap to initiate the change(s). The position on the small screen to tap to bring up these feature icons may
depends on the video meeting App and the device. So, you just practice to tap on various positions to figure
out the correct area of the screen to tap.
For PCs, you practice by placing the cursor at various position of the screen to find out the correct area of the
screen to place the cursor to bring out the feature icons.
1.7. Un-mute your Microphone When You Speak in Video Meeting
In the video meeting, if your microphone is turned off, the small microphone icon of your microphone will have a
tiled line striking across your small microphone icon. Tap on that muted microphone icon to turn on your
microphone when you want to speak in the video meeting. Otherwise, other participant will not be able to hear
what you are saying in the video meeting.
On the other hand, if you do not want to let the noise (such as your wireline phone ringing) in your room to
disturb the video meeting, you can turn off your microphone by tapping on the microphone icon.
1.8. Turn On Your Camera So That Other Participants Can See You
After you joined a video meeting, take a look of your video in the meeting. If your camera is turned off, the
small camera icon of your camera will have a tilted line striking across your camera icon. Tap on that small
camera icon to turn on your camera so that other participants can see you.
On the other hand, you can turn off your camera if you do not want other participants to see you or your untidy
1.9. Avoid Using Two Devices Nearby in the Same Video Meeting
Avoid using two devices, such as a smartphone and a PC, near each other in the same video meeting. The
microphones and the speakers in these two nearby devices can get into a positive feedback loop resulting in a
screaming loud noise that can bother not only you but also all participants in the meeting.
In case If you do need to use two devices together, please make sure that the microphone/sound of one of the
two devices is muted and the volume of the sound is shut off.
2. Using LINE App for Video Meetings
LINE App can accommodate up to 500 participants in a free group video conference call or a free group voice
2.1. Required Installation of LINE App on Your Device
You must download and install the free LINE App in your device in order to participate in the LINE based group
iPhone and iPad can get free LINE App from Apple App Store. Android based devices can get free LINE App
from Google Play Store. Laptop PC and desktop PC running Windows OS can get free LINE App from
Microsoft Store as shown in Picture 1 below near the end of this website.
After the installation of the LINE App, a green colored LINE icon (Logo) will show up on the basic screen of the
device as shown in Picture 2 below near the end of this website.
2.1.1. Limitation on Installation of LINE App on Multiple Devices
The smartphone version of LINE App can be installed on only one device (Android smartphone or Android
tablet, or iPhone or iPad) using one LINE Account with one phone number. With the smartphone version of
LINE App, the same set of LINE account and phone number cannot be used on multiple devices. Only one
phone number or email address can be used to verify one account per device. If you register the same phone
number on a different device, the LINE account on your previous device will automatically be deleted and you
will no longer be able to use the LINE App on the first device.
But there is an exception to this restriction on only one device. There is a PC version of LINE App that can be
installed on your PC using the same LINE account as that on your smartphone (or tablet or iPhone or iPad).
However, such dual installations on a smartphone and a PC requires using e-mail address (instead of phone
number) as login ID.
Using LINE App on a PC offers the possible advantages of (1) larger screen to see the contents on the screen
more clearly, (2) easier to copy the screen contents of LINE message and paste them into other files or e-
mails, and (3) easier to copy the longer contents from other files or e-mails and paste them into the LINE
message to be sent. This avoids the problem of trying to type a long document on the tiny keyboard of a
smartphone or iPhone as the LINE message.
Another exception to the limitation of only one device is to use another version of LINE known as LINE Lite
which is a trimmed down version of LINE. It seems that LINE Lite with the same LINE account can be installed
on a second device but it must be registered by e-mail address (instead of phone number). ( But I have no
experience using LINE Lite yet.)
2.2. How to Join a Video Meeting Using LINE App
2.2.1. The host of video meeting will send you a LINE message or an e-mail indicating the Date and the
starting Time of the video meeting.
2.2.2. On the date and the starting time of the video meeting, you will receive a LINE notification text and a
special ringing sound for the group meeting.
2.2.3. You tap on the LINE notification text. Then the screen will show a small video camera icon and the text
“Group Video Call Started” (or a small telephone icon and the text "Group Voice Call Started" if it is a group
voice conference call) with a blue colored word of “Join” below.
2.2.4. You tap on the blue “Join” icon on the screen to join the free video meeting.
Once you join the meeting, you may need to adjust the angle of your camera/device, adjust the location of light
source in your room and to turn on or off your microphone or camera as described in Sections 1.4., to 1.8.
2.2.5. At the end of video meeting, you tap on the red colored phone icon to leave or to end the video meeting.
2.2.6. Help for using various features in LINE App (in several different languages) is available at the following
or you may enter your question on how to use certain features of LINE App into Google Internet Search Box
and Google may find the answer for you.
2.3. How to Host a Video Meeting Using LINE APP
2.3.1. Creation of the Meeting Group
To prepare for a video meeting using LINE App, the host of the group creates a LINE Group of all the
participants for the meeting group, and gives the group a name, such as Classmates, in the List of LINE
Then the host sent a LINE notification or an e-mail to all group members inviting them to respond to join the
new LINE group to complete the group creation.
2.3.2. The host send a invitation LINE message to all members in the group about the date, the starting tine of
the video meeting and the purpose of the video meeting.
2.3.3. On the date and the starting time of the video meeting, the host taps on the green colored LINE icon on
his/her device to open the LINE App.
2.3.4. The host tap on the Chat icon on the screen to go to Chat mode of LINE
2.3.5. The host taps on the group name, such as Classmates, on the list of LINE Friends/Contacts to open the
group chat session.
2.3.6. The LINE App will present a small video camera icon and a small voice phone icon on the screen for the
host to choose as shown on Picture 3 below near the end of this website.
2.3.7. The host taps on the small video camera icon to start the free video meeting call (or on the small voice
phone icon to start the free group voice conference call).
2.3.8. All group members will receive a LINE notification text and a special ringing sound for the video meeting.
2.3.9. Interested group members respond by Step 2.2.3 above to join the free video meeting.
2.4. Initiation of the Group Conference Call
After the completion of the creation of the new LINE group, I think any member in the group can initiate the
group video conference call or group voice call.
3. Using Zoom App for Video Meeting
Usually a meeting host of a Zoom video meeting will send you an invitation to invite you to join the video
meeting. This invitation may come in an e-mail or a text message or a LINE message with the date, the
starting time and the topic for the video meeting.
The invitation message also contains an URL Link that may look like:
where xxxxxxxxx is a 9-digit or 10-digit number which is the ID for this particular Zoom video meeting.
Assume that you have done the preparation work in Section 3.3., and have received an invitation e-mail (or
invitation message) to join a Zoom video meeting, then the procedure to join a Zoom video meeting is very
simple as follow:
3.2. The procedure to join a Zoom video meeting is quite simple as follows:

3.3.3. At the end of the Zoom video meeting or if you need to leave before the end of the video meeting, you
click on the red colored “Leave the meeting” at the lower right corner of the screen to leave the meeting.
3.3.4. Using Zoom App on a PC, instead of a smartphone or a tablet or an iPhone or an iPad, offers the
possible advantages of (1) larger screen to see the contents on the screen more clearly, (2) showing more
small icons on the lower edge of the screen for user to access more advanced features of Zoom easily. For
example, a small icon of a downward arrow next to the small icon of camera allows the user to access the
menu to change the optional background screen (backdrop) of the video in the video meeting. Such small
downward arrow icon is not available on the screen of a tablet.
3.3.5. Choose Your Preferred Backdrop of Your Video in Zoom Video Conference
On the Zoom meeting screen, there are several small icons for the host and the participants to use various
features in the Zoom App. More details on these features can be seen here. For example, the small
microphone icon on the lower left corner of the screen is for you to mute or un-mute your voice in the video
The next small camera icon just to the right of microphone icon is for you to do something about the video. For
example, if you click on the small down arrow just to the right of the small camera icon, a menu will show
several things that you can do to the video. One of the items on this menu is for you to choose a desirable
backgrounds or backdrops behind you. The optional backgrounds that you can choose are beautiful pristine
beach with ocean waves or majestic San Francisco Golden Gate Bridge, etc. These artistic backdrops free
home users from worrying about whether their half-dressed spouse and children are in the webcam’s sight-line
or to hide the cluttered room behind you. More detailed explanation can be seen here.
3.3.6. Zoom Service Plans
Zoom video services have several different levels/plans of service with different price. The basic level is free
and is good enough for casual social video meetings. It can accommodate up to 100 participants (including the
host). For one-on-one free Zoom video meeting, there is no time limit. However, for the free basic level for a
group of 3 or more people, the meeting time is limited to 40 minutes. Once the 40-minute time is used up, the
group can restart the meeting and re-join for all attendees, the group will then get another 40 minutes. The
group can keep repeating this if the group runs out of time again. So, in this way, the group does not need to
pay any Zoom service fee.
Clients who pay a monthly fee of $19.99 per meeting host can gather as many as 1,000 people on a single

Google Meet video meeting.
If you have not been using a Google Account, a benefit of creating and having a free Google Account is having
a free backup spare e-mail address for protection of your e-mail services. It is well known that there are many
hackers causing various problems on Internet and e-mail services such that your regular e-mail system may be
in trouble for several hours or even several days. When such unexpected outage happens on your regular e-
mail system, but you still need an e-mail system for important communications with your contacts. In such
