dc.description.abstract We introduce T9+HUD, a safer method for in-car text entry, built from a 12 key physical keypad with T9 technology attached to the steering wheel and a head-up display that projects text to the windshield. The benefits of this method are the physicality of the input device and the location of the output in front of the driver. Present-day in-car text entry methods are distracting, forcing drivers to repeatedly shift their gaze from the road to the device. In addition, they make use of knobs, touch displays and buttons located in the central stack of the car, all of them lack proper feedback to grant drivers with the certainty that their input is correct without removing their eyes from the road. Research in the automotive domain has focused on input devices positioned on the steering wheel e.g. handwritten recognition, gestures on a touch pad, buttons on the back of the wheel and virtual buttons on a head-up display, however none of them have achieved safety results that can be recommended. We conducted a user study in a simulated driving environment, in which subjects were assigned with a simultaneous driving and text transcription task. We compared it to our baseline design and showed that it reduced driving errors by 70% while maintaining similar text entry performance as industry solutions. en
