7.4.1 Creating a New Profile

Use of different profiles allows you to store multiple peoples calibrations and feedback preferences on one device. Alternatively,

one person might want to store multiple profiles for him/herself if that person wears glasses occasionally or uses multiple means

of accessing the device.

To create a new profile:

1. Open Gaze Interaction Settings, select User Profiles.

2. Enter a new name in the Profile name field.

3. Select an existing profile in the Based on profile drop down list. The new profile will inherit all settings from the se-

lected profile. Note that if no profiles have been created previously, the only one to select is the default profile.

4. Click Create to save the new profile. The new profile is saved directly upon selecting Create.
