Holding and releasing virtual objects
Techniques and devices for holding and releasing virtual objects on a display based on input received from one or more handheld controllers are described herein. In some instances, a handheld controller includes one or more sensors, such as proximity sensors, force sensors (e.g., force resisting sensors, etc.), accelerometers, and/or other types of sensors configured to receive input from a hand of a user gripping the handheld controller. Hardware, software, and/or firmware on the controller and/or on a device coupled to the controller (e.g., a game console, a server, etc.) may receive data from these sensors and generate a representation of a corresponding gesture on a display, such as a monitor, a virtual-reality system, and/or the like.
