Targeting experiments help HCI researchers and practitioners to quantify interactions - for example by analysing speed/accuracy according to Fitts' Law. In contrast, touch offset models capture spatial patterns of touch inaccuracy across the screen. This enables new analyses and applications.
TouchML comes with a large database to start training and applying models right away. In a controlled lab study, we collected 4 target types × 400 target locations × 2 hand postures × 24 participants × 2 sessions = 153.600 touches.
