  • AN INPUT DEVICE AND A METHOD FOR PROVIDING A SCROLLING INPUT TO A COMPUTING DEVICE
    Publication number: 20230333674
    Abstract: An input device (900) may include a rotatable member (952), a virtual scroll controller (912) and a host interface block (906). The virtual scroll controller (912) may be configured to select a virtual scroll state from a plurality of virtual scroll states based on a rotational velocity of the rotatable member (952). Each virtual scroll state may be associated with a respective output function. The virtual scroll controller (912) may be further configured to compute an output velocity according to the output function associated with the selected virtual scroll state. The virtual scroll controller (912) may be further configured to generate a virtual position count (928) based on the computed output velocity. The host interface block (906) may be configured to send the generated virtual position count (928) to a computing device connected to the input device (900).
