This idea is probably generated from the common texting and walking phenomenon. However after I tried the spilt keyboard system, I realized it is not completely comfortable. It is because our eyes are not design to look at two keyboard at the same time. Therefore I had a idea that we should just spilt the keyboard into one section. While walking and typing at the same time.
