摘要： Methods, devices, and processor-readable media for scaling up graphical user interface (GUI) elements on a smart watch touchscreen based on the initial position of a stroke gesture, thereby facilitating selection, by a user, of a target GUI element. The user only needs to perform one stroke action to select the desired target. During the procedure, GUI elements of the main screen are scaled up to make target selection easier, and the GUI elements are automatically reset to their original size when the procedure is complete. To achieve this result, a “stroke with initial position” gesture is used to select a target.

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： A method for preparing a shallow trench isolation structure with the stress of its isolation oxide being tuned by ion implantation comprises: step a: forming a protective layer on a semiconductor substrate; step b: forming trenches for isolating PMOS active regions and NMOS active regions on the semiconductor substrate and the protective layer; step c: forming a filling material layer in the trenches, so that the trenches are fully filled with the filling material layer to form shallow trench isolation structures. The advantageous is that, as for a device where a HARP process is applied to its shallow trench isolation, the stress in the STI can be tuned so as to be changed from tensile stress into compressive stress by performing ion implantation to the STI around the PMOS, therefore the stress state of the PMOS channel region may be changed and the performance thereof is improved.
