The method feature is that (i) the vector of a control action made by the user with the RC, (ii) the vector of the desired motion for the selected toy and (iii) the vector displayed by light indicator at the selected toy, all the three, or at least two of them, have coincided direction and proportional value. The desired vector is being set while the RC is pointed at the selected toy. If pointing is being made by invisible light, then the pointed toy should be indicated by its own means. One RC may be used for controlling arbitrary number of devices consequently. Otherwise a number of toys may be grouped, and the same MV may be given to all of them at once. ## Claims ### Claim at position 1 1-6.
