The question was asked as to gain incite to the possibility of other apparatus or applications to assist in the daily functions of typing, using one hand.

The question was not asked to gain sympathy, meant to extract an opinion nor was it derogatory. The Ask Ubuntu forum should be proud to help out. My personal opinion may be subjective, just ask me.
