The ergonomics aspects of the design of a domestic telephone are outlined as a case study. The main usage points investigated were: handset relationship to ear and mouth together with adequate finger clearance at the cheek; general comfort when picking up and holding the handset; replacing the handset correctly in order to operate the hook-switch; establishing an acceptable compromise for dial and keypad angle at 15 degrees ; and devising a wall mounted unit.
