  • a further advantage provided by the use of COTS mobile user apparatuses is that when oil on a sea surface needs to be collected, any kind of a vessel, like a fishing vessel or a pleasure boat, may be used as the right/left hand side vessels without any extra training or additional equipment or any need of the steering person in the right/left hand side vessel to understand the language used in the vessel collecting the oil or to be a professional navigator; it suffices that either a mobile user apparatus in the vessel is tailored to act as a slave, or they are provided with such a mobile user apparatus.

  • Other instructions may include "turn to left", displayed by an arrow pointing to the left, “slow down” displayed by an arrow pointing downwards and “speed up” displayed by an arrow pointing upwards.
  • the instructions may also be delivered using one-to-one voice call, or a group voice call or using messaging, like SDS messages in TETRA, and/or other indicators than arrows may be used to indicate the intended and indicated movement change.

  • the slave 702 has drifted to the left due to a late start of turn but is still barely on the target area 703. Since the relative movement direction 705 points to the left and the aim is that it points upwards, a user is indicated to turn to right just by noticing the relative movement direction 705. Naturally, an additional arrow (like the arrow 706 illustrated in Figure 7B) or corresponding information may be displayed. Further the user is indicated to increase the speed so that the slave reaches the position in the center of the target area.

  • the slave 702 is outside the target area 703. Since the relative movement direction 705 points to the right and the aim is that it points upwards, a user is indicated to turn to left. Further the user is indicated to increase the speed so that the slave reaches the position in the center of the target area.
  • the target area is shown as stable on the display but the displayed position of the slave may change.
  • An advantage provided by that is that it is very intuitive to the person trying to maintain the vessel (or any other "thing", including himself/herself) within the target area so that a change of direction or speed is immediately obvious, as is illustrated with Figures 7C and 7D.
  • No training is needed. That is especially useful when a sudden need for searching for a person lost in woods arises since then more people are able to use the apparatus, and therefore the search group may be bigger and still is able to maintain its formation/configuration synchronized a longer period compared to use of mere vision and/or voice.
  • Each stop because of "reformation” causes a delay that may have severe consequences. The same applies when oil is collected on the sea surface; each stop reduces the efficiency of the oil collection. Further, compared to using mere voice and messaging, misunderstandings and mishearing are avoided.
