Casper Focus

Casper Focus is designed to be used by teachers in the classroom. It gives teachers control over the devices used during class time by allowing the teacher to “focus” the devices on a single app, website, or attention screen. Focusing a device locks it on the app, website, or attention screen, preventing students from accessing any other screens or content on the device.

In addition to focusing student devices, teachers can also perform the following actions in Casper Focus:

  • Clear passcodes on student devices.

  • Use AirPlay Mirroring to show the screen of a student device on Apple TV.

  • Distribute eBooks (ePub format only) so that students can install the eBooks on their devices from Self Service.

Casper Focus is available for free from the App Store.

Before Using Casper Focus

In addition to ensuring that mobile devices meet the requirements for using Casper Focus, you also need to perform the following tasks to allow teachers to use Casper Focus:

  • Create classes in the JSS—The classes you create in the JAMF Software Server (JSS) allow teachers to use Casper Focus to control student devices during class time. (For more information, see Classes.)

  • Preconfigure the connection to the JSS—Casper Focus must be able to connect to the JSS to work. To do this, the JSS URL setting in Casper Focus must be populated with the JSS URL. With this setting preconfigured, teachers can log in and use Casper Focus without having to manually configure the JSS URL themselves.
    For more information on preconfiguring the JSS URL, see the following Knowledge Base article:
    Configuring Server Settings for Casper Focus

  • (Optional) Add an LDAP server to the JSS—Integrating with an LDAP directory service allows teachers to log in to Casper Focus using the username and password for their LDAP directory account. (For more information, see Integrating with LDAP Directory Services.)
    If you do not have an LDAP server set up in the JSS, teachers can log in to Casper Focus with a JSS user account.

  • Check Web Content Filter payload settings—If you currently use the Web Content Filter payload in an iOS configuration profile to limit student devices to specific websites only, you need to ensure that the payload’s Specific Websites list includes the URLs of any websites that teachers will focus student devices on.

  • Specify AirPlay passwords for Apple TV devices—If teachers will be mirroring student devices on Apple TV using Casper Focus and the Apple TV devices are configured with AirPlay passwords, you will need to specify the AirPlay password for each Apple TV by editing its inventory information in the JSS. (For more information, see Viewing and Editing Inventory Information for a Mobile Device.)
