This is a variation on the above alphabet, modified for tactile use by those communicating with people who are deafblind.
The receiver's hand is relaxed, with the palm open and fingers slightly apart.
As a beginner, you may squeeze the wrist of the receiver between words since you will spell haltingly.
Once you can spell fluently, simply put a short pause between words.
