During the initial phase of Envision Glasses, different interface concepts were tested in prototypes and user feedback was gathered.
Based on user feedback, a 'Favorites' feature was introduced in Envision Glasses version 1.3 to provide quick access to frequently used functions.
Envision Glasses version 1.6 introduced Voice Commands to enable hands-free operation and immediate access to specific functions.
The development of the 'More features' menu allowed users to customize the main menu and organize additional tools for a simplified navigation experience.
