Screensharing options in a session hosted with integrated video on Handshake vary between browsers, and additional permissions may be required to share the first time.
Users are only able to share their screen when joining on desktop web and cannot share screens via mobile web. General system specifications are outlined in Host Requirements for Integrated Video.
Note: students can share their screen via the Handshake mobile app for iOS, as long as the session host as enabled participant screensharing.
Details of each supported browser describe steps from the time that you've clicked the share screen icon in the lower-middle of the video display, with the expectation that your browser is the most recent version.
All example images are on a Mac–specific details may vary if you're on a Windows computer!
Topics:
- Supported browsers - click the name of the browser you're using for specifics:
- Mac system requirements for screen sharing
- Sharing prerecorded video
Chrome
In Chrome, sharing options allow you to select from:
- your entire screen
- an application window
- If you're on a Mac and using Spaces, only application windows in the same space are displayed. If an expected app is missing, move the window to the same desktop space your browser is in!
- a specific Chrome tab
Click the desired item to share, and a preview displays in the popup. If the shared item is as expected, click Share.
When an active share is in progress, the screenshare icon is highlighted initially with a black and green ring. When you click onto anything else, the highlight changes to only a green ring.
Alerts are displayed based on the chosen share option:
- sharing your full screen: a message overlay appears over the icons at the lower-middle of the page that reads "SITE is sharing your screen.
- sharing a window: a message overlay appears over the icons at the lower-middle of the page that reads "SITE is sharing a window."
- sharing a specific tab: the tab has a blue rectangle, indicating active sharing, and in the upper-left corner of the page, a message says "Sharing this tab to SITE"
At any time, click the share icon to stop sharing, or if the screen share message is displayed (as in the examples above), click the blue button Stop sharing to stop.
Firefox
In Firefox, a prompt appears to "Allow SITE to see your screen?"
The Window or screen dropdown menu has the following sharing options:
- another application
- If you're on a Mac and using Spaces, only application windows in the same space are displayed. If an expected app is missing, move the window to the same desktop space your browser is in!
- a specific Firefox tab
- your entire screen
Click the desired item to share, and a preview will appear below. If the preview is as expected, then click Allow.
When an active share is in progress, the screenshare icon is highlighted initially with a black and green ring. When you click onto anything else, the highlight changes to only a green ring.
Alerts are displayed based on the chosen share option:
- sharing another application: a message appears at the upper-middle that says "You are sharing another application window."
- sharing entire screen: a message appears at the upper-middle that says "You are sharing your entire screen."
- sharing the browser: a message appears at the upper-middle that says "You are sharing Firefox."
At any time, click the share icon to stop sharing, or if the screen share message is displayed (as in the examples above), click the blue button Stop sharing to stop.
Safari
Safari users are limited to sharing the full screen only and cannot choose individual apps/browser windows, etc. A popup appears to "Allow 'SITE' to observe your screen?" To share your screen, click Allow.
This prompt will appear each time you click share, even if you stop sharing and start sharing again in the same session.
If the prompt doesn't appear, check Safari Preferences > Websites to ensure Handshake is set to Ask.
When there is an active share, the computer icon is highlighted with a green circle.
The address bar also displays two red rectangles overlapping, indicating an active share. If you have multiple tabs open, this same icon is displayed on your video session tab in gray.
At any time, click the share icon to stop sharing, or you can click the red rectangles in the address bar to Pause instead.
MS Edge
In Edge, sharing options allow you to select from:
- your entire screen
- a window
- If you're on a Mac and using Spaces, only application windows in the same space are displayed. If an expected app is missing, move the window to the same space your browser is in!
- a specific Edge tab
Click the desired item to share, and a preview displays in the popup. If the shared item is as expected, click Share.
When an active share is in progress, the screenshare icon is highlighted initially with a black and green ring. When you click onto anything else, the highlight changes to only a green ring.
Alerts are displayed based on the chosen share option:
- sharing a window: a message overlay appears over the icons at the lower-middle of the page that reads "SITE is sharing a window."
- sharing entire screen: a message appears at the lower-middle that says "SITE is sharing your screen."
- sharing a specific tab: the tab has a colored rectangle indicating active sharing, and in the upper-left corner of the page, a message says "Sharing this tab to SITE"
At any time, click the share icon to stop sharing, or if the screen share message is displayed (as in the examples below), click the blue button Stop sharing to stop.
Mac system requirements for screen sharing
To share a screen or window on a Mac, you must give each specific browser or app permission.
1. Open System Preferences, then select Security & Privacy.
2. Click the lock in the lower-right corner to authenticate for changes.
3. Select the Privacy tab, select Screen Recording, then check the box for the desired browser.
If the browser is open when you change this setting, you must quit and reopen the browser for the changes to take effect.
- Tip: for a smooth experience, make sure this permission is granted prior to your session start time!
Sharing prerecorded video
There is not a Handshake supported way to play a pre-recorded video during a session, however, if you are able to share your screen during the session and play a video via a tab, window, or another application, you can do that.
If you choose to share a video in this manner, the audio will play from your computer's selected speaker and feed back into the selected microphone, so make sure there are no headphones connected and your mic volume is increased to pick up the audio!
We'd recommend testing this setup with a colleague ahead of time to confirm functionality.
