Posted under Human Computer Interaction

Answer: (a).Concave plane or split keys for each hand Explanation:More ergonomic keyboard designs have altered the basic tilted planar base of the keyboard. Moderate designs curve the plane of the keyboard, making it concave, while more extreme ones split the keys into those for the left and right hand and curve both halves separately. These designs are meant to aid comfort and reduce Repetitive Strain Injury (RSI) by minimizing effort.
