We introduce T9+HUD, a text entry method designed to decrease visual distraction while driving and typing. T9+HUD combines physical 3x4 keypad on the steering wheel with head-up-display (HUD) for projecting output windshield. Previous work suggests this may be visually less demanding way type than popular case which requires shifts of attention away from road. present prototype design report first results controlled evaluation in simulator. While driving, rate was equal compared dashboard-mounted touchscreen device, but it reduced lane deviations by 70%. Furthermore, there no significant difference between baseline lane-keeping performance. decreased glance time off road 64% comparison QWERTY. conclude that data are favorable warrant more research attention-reducing input methods driving.
