Description:Field of the invention
[0001] The present invention relates to an input device. More specifically, the present invention relates to an input device for interfacing with an electronic device.

Background of the invention
[0002] Presently, input devices are essential components for interfacing with computer systems, enabling users to provide commands, navigate interfaces, and input data. The traditional input devices, such as keyboards and mice, operate as different input devices, with keyboards used for text entry and mice used for cursor control. To control these two functions two separate devices are required which limits the adaptability of input systems, particularly in a situation where compact and multifunctional solutions are required.

[0003] The keyboard is effective for typing but is fixed in layout and size, making it less suitable for portable or space-constrained environments. Further, a separate interface is required for cursor control, such as a mouse or a touchpad, which adds to the bulk and complexity of the computer system. Furthermore, physical keyboards are limited in their ability to adapt to user-specific requirements, such as dynamic layouts or specialized input methods.

[0004] Similarly, the traditional mouse is designed for pointer control and relies on fixed buttons and scroll wheels for input. The mouse offers precise movement detection, but it lacks the ability to provide multi-functional input or adapt to modern user interfaces that demand seamless transitions between typing and pointer-based interactions. Currently, users rely on multiple separate devices such as keyboards, mice, and additional input devices which creates inefficiencies in workflows and is challenging for users working in compact or mobile setups.

[0005] The existing technologies in input devices, do not adequately meet the demand for a compact, multifunctional, and adaptable input device that enhances user interaction without sacrificing comfort or precision.

[0006] Therefore, there is a need for an input device for interfacing with an electronic device to overcome a few or all drawbacks of the existing technologies.
