Problems solved by technology
Therefore, there may be a disadvantage that the exterior of the wearable device may not be round or beautiful due to a shape or structure protruding to the outside of the outer case that is not integrated with the outer case, and the wearable device may occupy a relatively large space.
[0006] In addition, there is a risk of electric shock due to direct contact with an electrically connected mechanical switch, and in particular, there is a disadvantage that it may be difficult to obtain a waterproof and dustproof construction of a wearable device due to the structural characteristics of the mechanical switch.

The invention provides a touch sensing method and an electronic device including a touch sensing device. The touch sensing method includes: generating respective oscillation signals having a resonant frequency, the respective oscillation signals being changeable according to a plurality of touch inputs applied to a first touch switch unit and a second touch switch unit, formed in a housing of an electronic device; analyzing the applied plurality of touch inputs, based on a change in the resonant frequency of the generated oscillation signals; and discerning and sensing a type of a touch operation according to a pattern of the plurality of touch inputs, based on results of the analyzing of the applied plurality of touch inputs.
Description
[0001] This application claims the benefit of priority from Korean Patent Application No. 10-2020-0083287 filed with the Korean Intellectual Property Office on July 7, 2020, the entire disclosure of which is incorporated by reference for all purposes here. technical field [0002] The following description relates to touch sensing methods and electronic devices including touch sensing devices. Background technique [0003] In general, wearable devices have become thinner, simpler, and have been implemented with sleeker, more aesthetically pleasing designs. Therefore, with the implementation of dustproof and waterproof technologies, and the development of integrated models with smooth designs, existing mechanical switches are being eliminated. [0004] Currently, technologies such as a touch-on-metal (ToM) technology that realizes a touch input on metal, a capacitor sensing technology using a touch panel, a micro-electro-mechanical system (MEMS), and a micro-strain gauge are...
