A system comprising one or more processors configured to: track a location of a stylus device within a physical environment via a three-dimensional tracking system, wherein the stylus device is coupled to a virtual reality display system and wherein the tracking of the location of the stylus device is used for interacting with the virtual reality display system; and modify a tracking parameter of the 3D tracking system while tracking the location of the stylus device based on the tracked location of the stylus device within the physical environment , wherein modifying the tracking parameter of the stylus device further includes: tracking the location of the stylus device according to a first tracking accuracy profile in response to determining that a user of the stylus device is operating said stylus device "in-air" in 3D space; tracking the location of the stylus device according to a second tracking accuracy profile in response to determining that the user of the stylus device is operating said stylus device along a two-dimensional surface ; and tracking the location of the stylus device according to a third accuracy tracking profile in response to determining that the user of the stylus device is operating the stylus device "in-air" in 3D space and bracing their arm against a surface . track a location of a stylus device within a physical environment via a three-dimensional tracking system, wherein the stylus device is coupled to a virtual reality display system and wherein the tracking of the location of the stylus device is used for interacting with the virtual reality display system; and modify a tracking parameter of the 3D tracking system while tracking the location of the stylus device based on the tracked location of the stylus device within the physical environment , wherein modifying the tracking parameter of the stylus device further includes: tracking the location of the stylus device according to a first tracking accuracy profile in response to determining that a user of the stylus device is operating said stylus device "in-air" in 3D space; tracking the location of the stylus device according to a second tracking accuracy profile in response to determining that the user of the stylus device is operating said stylus device along a two-dimensional surface ; and tracking the location of the stylus device according to a third accuracy tracking profile in response to determining that the user of the stylus device is operating the stylus device "in-air" in 3D space and bracing their arm against a surface . tracking the location of the stylus device according to a first tracking accuracy profile in response to determining that a user of the stylus device is operating said stylus device "in-air" in 3D space; tracking the location of the stylus device according to a second tracking accuracy profile in response to determining that the user of the stylus device is operating said stylus device along a two-dimensional surface ; and tracking the location of the stylus device according to a third accuracy tracking profile in response to determining that the user of the stylus device is operating the stylus device "in-air" in 3D space and bracing their arm against a surface . <EOS>
