Abstract: In a handwriting recognition system, a fingertip-motion sensing device has first and second body parts respectively wearable on a distal phalanx and a proximal phalanx of a finger, and a bendable bridge connecting the two body parts. An accelerometer module in the first body part generates acceleration data of the fingertip motion whereas a battery module powering the accelerometer module is in the second body part, avoiding the first body part to be loaded with the battery module so as to reduce hindrance to a user in handwriting. The bridge is wavily shaped, enabling it to be extensible and retractable to avoid spurious interference generation due to unintended movement between the first body part and the distal phalanx. The sensing device wirelessly transmits the acceleration data to a computing device, which analyzes the acceleration data to determine handwritten characters by using a machine-learning classifier, preferably a convolutional neural network.

Abstract: A multimodal haptic feedback interface installed with a multimode haptic patch stimulates a skin area of a user to provide a haptic feedback including first and second haptic-feedback components to be sensed under static tactile sensing and dynamic tactile sensing, respectively. The patch is mounted with mechanical actuators, electrostimulation electrodes and thermoelectric pellets. The actuators generate a two-dimensional pattern of pressure on the skin area for generating the first haptic-feedback component.

The actuators and electrostimulation electrodes are optimized only for static tactile sensing and dynamic tactile sensing, respectively, reducing an implementation cost while optimized for accuracy in haptic feedback generation.
