Methods and apparatus to identify haptic vibrations of touchscreens are disclosed. Example apparatus disclosed herein obtain a haptic control signal that is to cause vibrations of a touchscreen to simulate a texture corresponding to visual subject matter to be displayed on the touchscreen, the vibrations of the touchscreen to produce an acoustically detectable signal. Disclosed example apparatus also encode a watermark into the haptic control signal to generate a watermarked haptic control signal, the watermark including identification information to identify at least one of the subject matter or the texture, the watermark to modify the acoustically detectable signal.

The present invention provides improved methods and systems for assisting a user when interacting with a graphical user interface by combining gaze based input with gesture based user commands. The present invention provide systems, devices and method that enable a user of a computer system without a traditional touch-screen to interact with graphical user interfaces in a touch-screen like manner using a combination of gaze based input and gesture based user commands. Furthermore, the present invention offers a solution for touch-screen like interaction using gaze input and gesture based input as a complement or an alternative to touch-screen interactions with a computer device having a touch-screen, such as for instance in situations where interaction with the regular touch-screen is cumbersome or ergonomically challenging. Further, the present invention provides systems, devices and methods for combined gaze and gesture based interaction with graphical user interfaces to achieve a touchscreen like environment in computer systems without a traditional touchscreen or in computer systems having a touchscreen arranged ergonomically unfavourable for the user or a touchscreen arranged such that it is more comfortable for the user to use gesture and gaze for the interaction than the touchscreen.

Systems and methods that provide audio feedback in response to gesture validity can provide a more intuitive interface that can train users to correctly complete gestures. Moreover, systems and methods that provide line-specific audio feedback can provide more specific feedback that can allow a user to better understand what sensing line is being contacted. The systems and methods can further include basing the audio feedback based at least in part on obtained activity data, such that invalid and valid feedbacks can provide different sounds dependent on the determined activity state.

Embodiments of the present invention provide an application display method and a terminal, where the method includes: acquiring a first flicking gesture, where a start position of the first flicking gesture is located in a first preset operating area; and when the terminal detects that the first flicking gesture is a first preset flicking gesture, displaying an application that is in a first state, where the first state includes at least one of the following states: a state of running in the foreground, a state of running in the background, and a state of being buffered in the background. Therefore, a recently used application can be displayed to a user according to a gesture of the user, without a need to dispose a dedicated button, thereby improving operation and control efficiency.
