With dwell time activation, completely hands free interaction may be achieved by tracking the user's gaze positions. The first study presented compares typing by mouse click with dwell time typing on Danish on- screen keyboard with 10 large buttons which change according to character prediction. The second study compares mouse and eye-gaze dwell input on a similar Japanese keyboard, but without dynamic changes. In the first study, dwell time selections tend to be a little slower and the overproduction is higher than with click selections. In the second study, mouse and gaze is almost equally fast, but mouse is far more precise than gaze. Consequently, the productivity in terms of characters per minute is 33% higher. The results suggest that users can be productive from the first encounter with dwell time activation, but productivity depends on their familiarity with the input structure and the input mode (i.e. hand or eye).
