10 . Distancing during the COVID-19 pandemic has made both physical and social connections a touch more difficult to maintain. For Stanford University student Millie Salvato, being apart from her friend on the opposite coast has proved challenging. Sometimes a text or video call is not enough, and people in Salvato’s situation often long for a way to send a comforting hug from afar. In a new study detailed in IEEE Transactions on Haptics, she and her colleagues demonstrated a wearable sleeve that can simulate (模拟) human touch and convey social messages sent electronically.
Salvato and her team measured how 37 participants expressed social messages in different situations. In each test, one person wore a pressure-sensing device on an arm, and another touched it to respond to six different scenes: attention seeking, gratitude, happiness, calming, love and sadness. After collecting 661 touch movements, Salvato and her colleagues mapped the location and pressure of each. Next, they used a machine-learning algorithm (算法) to select the movements that were most reliable part of each response. Finally, they programmed a wearable sleeve to simulate these movements using eight built-in disks that vibrate when electronically signaled. “The instant it received signals, I could feel the touch and identify its intended meaning.” One participant reported.
Even with no training, the participants correctly matched the simulated touches to the six scenes 45 percent of the time. For comparison, a previous study found participants could match scenes for touches from real human hands 55 percent of the time.
Gerling, a touch researcher at Harvard who was not involved in the study, said the invention was really surprising. But the study was small and needs to cover far larger groups of people to determine exactly which are the most desirable responses. Besides, he believes the sleeve surely will enjoy great popularity once launched on the market.
