Other notes
From here, let’s check the recommended environment for Zoom delivery locations.
Beware of background reflections
When using Zoom from a room other than the office, such as a room at home, it is necessary to take care not to include unnecessary objects in the background.
This is because a miscellaneous background can be a distraction for the other party and also lead to the risk of being identified.
Either move to a room with as few objects as possible, or set Zoom’s virtual background function by following the steps below to hide the background.
If you set the background in advance
- Launch the Zoom app
- Click “Settings (gear icon)” in the upper right corner of the screen
- Click “Backgrounds and Filters”
- Select from the list or select the “+” icon to upload any image / video
If you want to add a background during your meeting
- Launch the Zoom app and start the meeting
- Click the “△” to the right of “Stop Video” in the menu at the bottom of the screen
- Click “Choose a virtual background” (or “Choose a virtual background”)
- Select from the list or select the “+” icon to upload any image / video
When meeting in a backlit location
If you participate in Zoom with your video on, check how your face will appear.
The recommended environment is a place where the light hits your face well when you sit down.
In the case of backlight, the facial expression will be dark, and it will be difficult for the other person to see it, so be careful.
It is also recommended to set Zoom’s skin correction function according to the following procedure and adjust it to a state close to the recommended environment.
For desktop apps
- Launch the Zoom app and click “Settings (gear icon)” at the top right of the screen
- Click “Video” from the menu on the left side of the screen
- Check “Correct appearance” (“Apply video filters” for Mac)
For mobile apps
- Launch the Zoom app and tap “Settings” at the bottom right of the screen
- Tap “Meeting”
- Tap “Correct Appearance”
- Toggle on the switch for “Improve my appearance”
If you want stability, wired is recommended over Wi-Fi
When using Zoom, it is also important to choose a location with a stable internet connection.
Please note that if you use Zoom in a place where the Internet is unstable, the audio and video may be interrupted, or the meeting itself may be interrupted.
A wired connection is recommended over a Wi-Fi connection if the stability of the connection is important.
summary
- When using Zoom, it is necessary to meet the recommended environment for each device and OS.
- If you want to stabilize the communication speed of the Internet line within the recommended environment range, it is recommended to use a wired connection rather than a Wi-Fi connection.
- It is also important to choose a location that takes into consideration the reflection of the background and the brightness of the image.
Zoom is an excellent tool that can operate even on devices with relatively low specifications or in environments with slow communication speeds, but you can experience its convenience even more by making it as close to the recommended environment as possible.
Before using Zoom, make sure that the system requirements are met and that the distribution location is appropriate.
