Abstract: Systems and methods are provided for multimodal input collection. More particularly, the present disclosure relates to efficient and intuitive multimodal input collection for mobile devices. As an example, a mobile computing system (e.g., a smartphone, a tablet, a wearable device, etc.) can display a lock screen interface at a display device associated with the mobile computing system (e.g., an initial interface that requests interaction and/or authentication from the user before granting access to applications, etc.).
