Abstract
The previous chapter compared gaze controlled and finger tracking based pointing modalities and we found users found it difficult to home on target using the gaze controlled interface and even with finger tracking system in automotive environment. In this chapter, we have proposed an algorithm that can activate a target even before the pointer reaches on top of it. For a gaze controlled interface, the target will be activated as soon as the saccade launches near the target reducing the fixation duration required to activate a target. In the latter half of the chapter we discussed different fusion strategies to combine eye gaze and finger tracking systems together. The previous chapter already introduced multimodal eye gaze tracking system by combining eye gaze tracking with joystick and LeapMotion controller, this chapter takes forward the concept with more sophisticated fusion models.
