The finger cursor is only available on the HoloLens 2 to enhance the ' direct manipulation with hands' interaction mode.
In the Mixed Reality Toolkit (MRTK), we've created drag-and-drop cursors modules to help you build the right pointing experience.
Below is guidance on which type of cursor to use for each type of headset and interaction model. These pointing cursors work with different input modalities on HoloLens, HoloLens 2, and immersive headsets. There are 3 kinds of cursors: finger, ray, and head-gaze. You can use the feedback to communicate their intention to the device, which increases user confidence. The cursor feedback also lets users know what system responses to expect. Even though the cursor is a digital representation of where the device understands the user's attention to be, that's not the same as determining the user's intentions. Cursor feedback includes what area, hologram, or point in the virtual environment responds to input. A cursor provides continuous feedback based on where the headset believes a users current focus is at a given time.
