Description

FIELD OF THE INVENTION

The present invention relates to a keyboard arrangements and more particularly relates to ergonomic keyboard assembly with multiple degrees of freedom.

BACKGROUND OF THE INVENTION

Users, especially the ones spending hours in using keyboards, typically expect increased productivity as well as improved comfort while using keyboards. Ergonomic keyboards such as split or segmented keyboards and keyboards with variable sized keys, are becoming choice of such users. These keyboards often solve the general purpose of a keyboard. However, they pose significant drawbacks in terms of user convenience which results in physical stress and strain of the user. In addition, the user of traditional keyboards results in carpal tunnel syndrome: the repetitive motions and suboptimal positions of wrists while typing on these keyboards lead to compression of the median nerve in the wrist which results in pain, numbness, and tingling in the hand and fingers.

While existing ergonomic keyboards are split into two sides, they offer limited angle adjustments, which may not adequately accommodate the varying ergonomic needs of users with different wrist, elbow, and shoulder positions. Lack of angle adjustability results in discomfort or strain in the wrists, elbows, and shoulders over prolonged typing sessions, particularly for users with ergonomic sensitivities or pre-existing conditions. Consequently, users may experience decreased typing efficiency and productivity if the angles of segmented keyboard do not align with their ergonomic needs.

Further, keyboards without wrist height adjustability may not satisfy the ergonomic needs of users with varying hand sizes. Furthermore, none of the split keyboards have the swapping capability. The ergonomic keyboards are often non-collapsible due to their complex structure: accommodates multiple components to achieve the ergonomic structure, thus, making them less portable and less convenient for users traveling often. Such complex-structured keyboards apparently lack flexibility in usage and are inconvenience for the users with ergonomic requirements.

Hence there is a need for an ergonomic keyboard assembly that eliminates the physical stress and strain of the user, increases user comfort by providing multiple degrees of freedom to the user and is collapsible for increased portability.
