摘要： Systems and method for low-power gaze prediction on touch-enabled electronic devices using touch interactions are provided. The method includes receiving an input touch interaction applied to a touch interaction area on a touchscreen display of a touch-enabled device and obtaining, by a gaze prediction module, a predicted gazing area on the touchscreen display based on the input touch interaction. A touch-enabled device has a processor, a touchscreen display and memory storing instructions to carry out the method. The gaze prediction module may utilize a model based on Bayesian inference or convolutional neural networks. Advantageously, gaze prediction is achieved without the use of image-capturing devices and with low power consumption. This can be used to develop intelligent hands-free interactions and personalized recommendation systems.

摘要： Wireless sensing units, methods, systems, and processor-readable media for obtaining pressure data relating to one or more pressure locations of a surface area are described. A wireless sensing system includes a pressure monitoring device communicating with modular wireless smart floor tiles using RFID, either using an RFID reader or wireless network interface (e.g., 802.11). The tiles incorporate passive or active RFID tags. The tiles can be powered wirelessly, e.g. by a built-in piezoelectric power unit or by a wireless power source using magnetic resonance. A data capture circuit in each tile collects and saves the data for transmission to the floor pressure monitoring device. Various software applications can be enabled by the smart floor system, including fall detection and prediction, gesture input, intrusion detection, and user location tracking for smart home automation.
