PeR+ is sensitive to the touch, as well as to the pressure applied by the person. The integration of two types of sensors means that the carpet can recognise various perceptive activities of the person. It differentiates between being gently stroked and being hit. On a bigger scale, it could be sensitive to whether you are walking over the carpet quietly or hastily. Similar to the light body of PeP, PeP+ and PeR, the light body of PeR+ is also positioned in relation to the sensor input. The behaviour of PeR+ builds on the active behaviour as designed in PeP+. Furthermore, it integrates concepts from both the explorative behaviour and the perceptive qualities portfolio.
The person explores PeR+ by touching it. This modality means that there is a direct relation between the person’s activity and the awareness of PeR+ being explored. This relation is more direct compared to PeP+. It appears more complex to detect whether the artefact is being explored based on the person’s activity in space (PeP+), than the person’s activity of directly touching the artefact (PeR+). PeR+ is sensitive to a change in sensor input. Therefore the person has to be active for PeR+ to detect her as an intentional subject. When the person actively touches it, PeR+ is certain of being explored.
The activity of the person directly and continuously influences the behaviour of the light body. The manner of touching PeR+ influences the uncertainty of the light body and the speed at which the light body moves. When you gently stroke PeR+, the light will be calm and follow your movement. On the other hand, when you apply more pressure, the uncertainty and speed will increase. The light body moves more quickly and is less likely to stick with you.
