Pen as a mouse? But why!? There is no simple answer on it. In a world where most tasks are being operated by sitting in front of a computer for long hours, there is a high chance that you might harm yourself. The most common type of discomfort can come in the form of headaches, redness in the eyes, stiff muscles, or carpal tunnel syndromes. If these are left untreated, it can become a cause for different disabilities.
Thus, one must adopt systems that suit your body best and reduce the amount of strain that it causes you. Therefore, studying computer ergonomics is very essential, and implementing smart device options like using a pen as mouse is of utmost importance.
