A method comprising: recognizing a first two-handed gesture and a second two-handed gesture in a monitored scene space to at least partially define a shape and position of a computer-implemented virtual boundary in a corresponding monitoring space, wherein the first two-handed gesture in the monitored scene space specifies a first two points in the monitoring space and the second two-handed gesture in the monitored scene space specifies a second two points in the monitoring space; causing implementation of the computer-implemented virtual boundary in the monitoring space corresponding to the monitored scene space, wherein a shape and position of the computer-implemented virtual boundary is at least partially defined by the first two points in the monitoring space and the second two points in the monitoring space; and processing received data to generate a response event when there is a change in a portion of the monitored scene space relative to the computer-implemented virtual boundary in the corresponding monitoring space. |
