An apparatus for panning and zooming a holographic image, comprising: a sensor (112, 620) configured to sense positional information of a moving obj ect; a display system configured to display the holographic image in a mixed reality environment and configurable to project the holographic image into a field of view of a user such that the holographic image can also appear alongside real world objects to provide the mixed environment, wherein the display system is a part of a see-through head mounted display device; and a processor (200, 304, 36, 210, 632, 612, 800) in communication with the sensor and the display system, the processor is configured to: use the positional information to track the moving object, to recognize a gesture by the moving object; characterised in that the processor is further configured to: create a virtual shape at a location of the recognized gesture in a mixed reality environment; track a current position of the moving object and project the current position of the moving object to a projected position on the virtual shape; determine a first distance from the location of the recognized gesture of the moving object on the virtual shape to the projected position on the virtual shape; determine a second distance from the current position of the moving object to the virtual shape; compare the first distance to a first threshold and the second distance to a second threshold; pan the holographic image in the mixed reality environment when the first distance is greater than or equal to the first threshold; and zoom the holographic image in the mixed reality environment when the second distance is greater than or equal to the second threshold. a sensor (112, 620) configured to sense positional information of a moving obj ect; a display system configured to display the holographic image in a mixed reality environment and configurable to project the holographic image into a field of view of a user such that the holographic image can also appear alongside real world objects to provide the mixed environment, wherein the display system is a part of a see-through head mounted display device; and a processor (200, 304, 36, 210, 632, 612, 800) in communication with the sensor and the display system, the processor is configured to: use the positional information to track the moving object, to recognize a gesture by the moving object; characterised in that the processor is further configured to: create a virtual shape at a location of the recognized gesture in a mixed reality environment; use the positional information to track the moving object, to recognize a gesture by the moving object; characterised in that the processor is further configured to: create a virtual shape at a location of the recognized gesture in a mixed reality environment; track a current position of the moving object and project the current position of the moving object to a projected position on the virtual shape; determine a first distance from the location of the recognized gesture of the moving object on the virtual shape to the projected position on the virtual shape; determine a second distance from the current position of the moving object to the virtual shape; compare the first distance to a first threshold and the second distance to a second threshold; pan the holographic image in the mixed reality environment when the first distance is greater than or equal to the first threshold; and zoom the holographic image in the mixed reality environment when the second distance is greater than or equal to the second threshold.
