“…The most commonly used technology for wearable tactile interfaces, including commercial products, is vibro-tactile output. Other forms of actuations methods such as thermal [49,52,66], pneumatic [20,2], shear forces [23], ultrasound [68,55], wind flow [43] and brushing [58] have been demonstrated.…”
Figure 1. A Tacttoo rub-on tattoo enables feel-through and high-density tactile output. With less than 35µm in thickness, it closely conforms to fine structures of the skin. Tacttoos can be custom-designed for various body locations and taxel densities, and fabricated using DIY tooling.
“…We choose not to cover actuation techniques used to trigger a range of tactile sensations such as soft pneumatic [14], actuated cloth [33], nor Shape Memory Alloys based devices [26] as those techniques are not strong enough to actuate body parts.…”

ABSTRACTWe present the concept of Frozen Suit, a type of clothing that restricts users' movements at joint positions (e.g. elbow, knee) via a changeable stiffness jamming material. The suit can "freeze" users' body parts, for example during a game in order to provide the physical sensation of being frozen by an enemy. In this paper we first present the Frozen Suit concept and its potential applications. We then systematically investigate how to design jamming patches in order to sufficiently restrict an arm or a leg. In particular we used low-fidelity prototypes to explore the restricting power of different material and particles. In order to push this analysis further we conducted a controlled experiment in order to compare the perceived stiffness of different patches sizes attached to the elbow. We performed a paired comparison experience and used a Bradley-Terry-Luce model to analyze the subjective feedback from participants. We found that 20cm long x 7cm large is the most restrictive patch and that an increase in patch area correlates with an increase in perceived stiffness (quadratic). We finish by presenting a use case application with a game that we implemented where enemies can freeze the player.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
