A computing system for dynamically modifying an occlusion within a mixed reality environment, the computing system comprising: one or more processors ; and one or more storage devices having stored computer-executable instructions which are executable by the one or more processors for implementing a method that includes: presenting an occlusion within a mixed reality environment, wherein the presentation of the occlusion includes moving the occlusion corresponding to one or more user inputs ; detecting a movement attribute associated with the occlusion that is based on the one or more user inputs, the movement attribute comprising at least one of a velocity or acceleration ; determining whether the movement attribute meets or exceeds a predetermined threshold ; upon determining the movement attribute meets or exceeds a first predetermined threshold, modifying at least one of a transparency attribute of the occlusion to cause increased transparency of the occlusion, an edge display attribute of the occlusion to cause feathering of one or more occlusion edges or coloring of the occlusion ; and upon determining the movement attribute fails to meet or exceed the first predetermined threshold, refraining from performing said modifying for causing the increased transparency or feathering . one or more processors ; and one or more storage devices having stored computer-executable instructions which are executable by the one or more processors for implementing a method that includes: presenting an occlusion within a mixed reality environment, wherein the presentation of the occlusion includes moving the occlusion corresponding to one or more user inputs ; detecting a movement attribute associated with the occlusion that is based on the one or more user inputs, the movement attribute comprising at least one of a velocity or acceleration ; determining whether the movement attribute meets or exceeds a predetermined threshold ; upon determining the movement attribute meets or exceeds a first predetermined threshold, modifying at least one of a transparency attribute of the occlusion to cause increased transparency of the occlusion, an edge display attribute of the occlusion to cause feathering of one or more occlusion edges or coloring of the occlusion ; and upon determining the movement attribute fails to meet or exceed the first predetermined threshold, refraining from performing said modifying for causing the increased transparency or feathering . presenting an occlusion within a mixed reality environment, wherein the presentation of the occlusion includes moving the occlusion corresponding to one or more user inputs ; detecting a movement attribute associated with the occlusion that is based on the one or more user inputs, the movement attribute comprising at least one of a velocity or acceleration ; determining whether the movement attribute meets or exceeds a predetermined threshold ; upon determining the movement attribute meets or exceeds a first predetermined threshold, modifying at least one of a transparency attribute of the occlusion to cause increased transparency of the occlusion, an edge display attribute of the occlusion to cause feathering of one or more occlusion edges or coloring of the occlusion ; and upon determining the movement attribute fails to meet or exceed the first predetermined threshold, refraining from performing said modifying for causing the increased transparency or feathering . <EOS>
