  • Patent number: 11809702
    Abstract: The disclosed technologies address various technical and user experience problems by augmenting the functionality provided by virtual on-screen trackpads without requiring users to switch between modes. In this way, users can access extended functionality without interfering with expected traditional trackpad functionality (e.g. moving a cursor, clicking, and scrolling). In particular, technologies are disclosed for modeless digital pen input to a virtual trackpad, modeless gestures for summoning user interfaces, modeless gestures utilizing position relative to adjacent user interfaces, and modeless cursor control and interaction with virtual touch targets.
