On the topic of multifinger displays:

Dr. Bliss is right; two adjacent fingers are no better than one. Smith-Kettlewell experiments suggest that the failure to gain improvement is a selective-attention problem.

Perhaps if both fingers saw the same presentation, research might be warranted. However, cluttering the reader's view with more than one letter at a time will decreas the thru-put, not increase it.
