The Haptic Mirror project represents an embodiment of these extensive research efforts and seeks to establish connections between the human body and material through touching interactions. The central installation is comprosed of six sets of arms, a supportive metallic stand, and six stepper motors. Each arm consists of rigid dactylopodites connected by soft joints and actuated by tensioned cables. Importantly, each arm is independently activated by individual motors, enabling a wide range of versatile movements, thus facilitating diverse interaction modes:

​

As people enter the scene, the arms are set in motion. One curious arm may reach out first trying to emulate the iconic “Creazione di Adamo”. As people approach closer, certain arms may execute quick and delicate bending-releasing movements, just like some subtle tapping. When people fully immerse themselves in the installation domain, all arms may collectively tighten and enclose around people, resembling a trapping or a hug. The adaptability of the soft joints allows some arms to modify their positions and gently transition to another part of the body, which is like a caressing or petting motion. Since each arm is actuated independently, the combination of touching movements can be more diverse and captivating. Furthermore, beyond the consideration of haptics, the incorporation of inner and outer surfaces with varying textures and visual shapes is undertaken to create a multitude of sensory experiences.

​

In summary, the installation is purposefully created to engage with humans through haptic interactions. Its repertoire of diverse touch modalities, adaptable combinations, and a wide array of material components significantly enrich its capacity to foster profound emotional connections within embodied experiences. The enhanced connection and high consideration of holistic bodily perception, especially haptics, greatly fortify and amplify the materiality of human body.

Diverse Haptic Interaction Modes: in a & b, one arm reaches out to touch people or being touched; In c, d,e, Arms move in various frequency in different order to create unique interaction & experiences;   In f & g, all arms simultaneously enclose around people forming a trap or a hug.

Haptic Mirror is also the first trial of scaling up the [rigid links - soft joints - tendon cables] arm mechanisms. The shape and hardness of the joints have been tested and adjusted to help the arm hold its weight, which is utimately urethane with Shore 60A hardness.

The rigid links are also re-designed with inner surface and outer surface attached on to create a contrasting experience through the soft & adaptive tactile feeling and eerie & uncanny visual aesthetics.
