Similarly, preferred spacing distances 1512A and 1512B between the cutaneous actuators may be determined. For each of a set of spacing distances between the first cutaneous actuator 1508A and the second cutaneous actuator 1508B, the first haptic sensations and the second haptic sensations may be transmitted to each of several participants. For each of a set of spacing distances between the cutaneous actuator 1508C and the cutaneous actuator 1508D, the haptic sensations may be transmitted to each of several participants. A rating of the continuous tactile motion may be received from each participant for the spacing distance 1512A or 1512B. The received ratings may be aggregated to determine a preferred spacing distance 1512A or 1512B corresponding to a highest rating.
Similarly, a preferred overlap time may be determined between the generating of the first haptic sensations and the generating of the second haptic sensations. The haptic sensations may be transmitted to each participant of a set of participants for each of several distinct overlap times between the generating of the first haptic sensations and the generating of the second haptic sensations. A rating (e.g., pleasantness or continuity) of the continuous tactile motion may be received from each participant for each overlap time 1536. The received ratings may be aggregated to determine a preferred overlap time corresponding to a highest rating.
