“…Interaction techniques in this group require a complete head control ability for hands-free computer access. In principle, they translate the users' head movements into mouse cursor movements in several ways: One of the most popular techniques is wearing inertial sensors, such as a gyroscope or an accelerometer on the head (via a helmet or a cap) to control a mouse pointer [9][10][11][12][13][14][15][16][17][18][19]. These inertial sensor-based systems are mostly combined with a different sensor/switch to perform a mouse click task (e.g., in a way that head movements are detected by inertial sensors to control mouse pointer, and mouse clicks are performed by a puff switch).…”

Head-operated computer accessibility tools (CATs) are useful solutions for the ones with complete head control; but when it comes to people with only reduced head control, computer access becomes a very challenging task since the users depend on a single head-gesture like a head nod or a head tilt to interact with a computer. It is obvious that any new interaction technique based on a single head-gesture will play an important role to develop better CATs to enhance the users' self-sufficiency and the quality of life. Therefore, we proposed two novel interaction techniques namely HeadCam and HeadGyro within this study. In a nutshell, both interaction techniques are based on our software switch approach and can serve like traditional switches by recognizing head movements via a standard camera or a gyroscope sensor of a smartphone to translate them into virtual switch presses. A usability study with 36 participants (18 motor-impaired, 18 able-bodied) was also conducted to collect both objective and subjective evaluation data in this study. While HeadGyro software switch exhibited slightly higher performance than HeadCam for each objective evaluation metrics, HeadCam was rated better in subjective evaluation. All participants agreed that the proposed interaction techniques are promising solutions for computer access task.
