Problems solved by technology

[0004] However, touch sensors are not sensitive in certain areas (e.g. edge areas)
Therefore, even if the finger F has touched such an area of ​​the touch interface 101, the finger F cannot be sensed.
like figure 1 As shown, the finger F has touched the edge area E of the touch interface 101, but cannot be sensed due to the insensitivity of the contact sensor
Therefore, on the edge area E, the user cannot control the electronic device with gestures

Embodiment Construction

[0031] In the following description, a number of embodiments are disclosed to illustrate the concepts of the invention. Please note that the following embodiments can be implemented by means of hardware (such as a circuit), or by combining hardware with software (such as writing a program in a processor). Furthermore, certain terms are used in the specification and following claims to refer to particular elements. It should be understood by those skilled in the art that hardware manufacturers may use different terms to refer to the same element. The description and the preceding claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The term "comprising" mentioned throughout the specification and the preceding claims is an open-ended term, so it should be interpreted as "including but not limited to".

Abstract

The invention discloses a hybrid touch control method applied to an electronic apparatus comprising a touch interface. The hybrid touch control method comprises: (a) sensing if an object presses the touch interface to generate a pressure sensing signal; (b) sensing if the object touches the touch interface to generate a touch sensing signal; and (c) controlling the electronic apparatus according to the pressure sensing signal, but not according to the touch sensing signal. The step (c) can be replaced by: maintain or to stop an operation that the electronic apparatus is performing according tothe pressure sensing signal if the touch sensing signal indicates the object is in a predetermined region of the touch interface. Via such method, the electronic apparatus can still be well controlled even if the touch is performed to a region that is not sensitive to touch.

Description

technical field [0001] The invention relates to a hybrid touch method, in particular to a hybrid touch method that can control an electronic device according to pressure sensing when a touch event cannot be detected. Background technique [0002] Recently, electronic devices with touch functions are becoming more and more popular. A user can use an object, such as a finger or a stylus, to control the electronic device through a touch interface. However, existing touch methods have some disadvantages. [0003] figure 1 A schematic diagram illustrating an edge area where an object touches an electronic device. Such as figure 1 As shown, the electronic device 100 includes a touch interface 101 (eg, a touch screen). The user can control the electronic device 100 by performing a gesture on the touch interface 101 with an object (such as the user's finger F). Therefore, the electronic device 100 has a touch sensor (touch sensor, not shown) to sense the touch action performed...
