SwarmCloak: Landing of a Swarm of Nano-Quadrotors on Human Arms
We propose a novel system SwarmCloak for landing of a fleet of four flying
robots on the human arms using light-sensitive landing pads with vibrotactile
feedback. We developed two types of wearable tactile displays with vibromotors
which are activated by the light emitted from the LED array at the bottom of
quadcopters. In a user study, participants were asked to adjust the position of
the arms to land up to two drones, having only visual feedback, only tactile
feedback or visual-tactile feedback. The experiment revealed that when the
number of drones increases, tactile feedback plays a more important role in
accurate landing and operator's convenience. An important finding is that the
best landing performance is achieved with the combination of tactile and visual
feedback. The proposed technology could have a strong impact on the human-swarm
interaction, providing a new level of intuitiveness and engagement into the
swarm deployment just right from the skin surface.Comment: ACM Siggraph Asia 2019 conference (Emerging Technologies section).

HARVEST: High-Resolution Haptic Vest and Fingertip Sensing Glove That Transfers Tactile Sensation of Fingers to the Back
Human fingertips are densely populated with tactile receptors and are hence incredibly sensitive. However, wearing gloves on the fingers drastically reduces the tactile information available to the fingertips, such as the texture and shape of the object, and makes it difficult to perform dexterous work. As a solution, in this study, we developed a high-resolution haptic vest that transfers the tactile sensation of the fingertips to the back. The haptic vest contains 80 voice-coil type vibrators which are located at each of the two discrimination thresholds on the back and can be driven independently. The tactile sensation of the fingertips is transferred to the back using the developed haptic vest in combination with a sensing glove that can detect the pressure distribution on the finger skin at up to 100 points. Different experiments were conducted to validate the performance of the proposed haptic vest and sensing gloves. The use of the haptic vest and the sensing glove enabled the user to perceive the shape of a planar object more accurately when compared to the case where the user wore only the glove

Insulin: a critical autoantigen and potential therapeutic agent in Type 1 diabetes
Insulin is a polypeptide hormone secreted by pancreatic beta-cells and is critical for glucose homeostasis. Abnormalities in insulin secretion result in various forms of diabetes. Type 1A diabetes is an autoimmune form in which insulin has been identified as a critical autoantigen. Recent studies have identified genetic determinants of insulin-specific autoimmune responses and insulin epitopes targeted by autoreactive T lymphocytes. The study of insulin as an autoantigen has also led to discoveries about basic mechanisms of immunological tolerance and autoimmunity. Experimental and clinical evidence suggests that insulin and insulin-derived peptides may delay and perhaps prevent the development of diabetes. Further clinical trials may identify effective treatment modalities for inhibiting diabetogenic autoimmunity and preventing disease development
