A data acquisition device (10) representing a virtual object and adapted to be attached to a positional sensing device (60) comprises a handle (5) having at least one sensor (121, 122, 123) allowing a user of the device (10) to issue a handling signal of the data acquisition device (10). The handle (5) comprises at least two surface areas (110) adapted to be pushed in direction of the body of the handle (5). At least one force sensor (121, 122, 123) is associated to each of said surface areas (110) adapted to sense a pushing force of the user grasping and/or pressing the handle via the surface areas (110).
