Abstract
U području interakcije čovjeka i računala, pored akcije pokazivanja-i-odabira, često se formaliziraju i zadaci koji uključuju izvođenje neke zakrivljene trajektorije odnosno usmjeravanje pokazivača odgovarajućim tunelom. Uz motivacijsko uporište u Fittsovom zakonu, a s obzirom na specifičnosti zadatka crtanja krivulja, u radu je predložen i adekvatno argumentiran model za izračun težine zadatka i procjenu vremena potrebnog za izvršavanje takvog zadatka. Na temelju teorijskih osnova predloženog prediktivnog modela, proveden je HCI eksperiment s ciljem izlučivanja konkretnih inačica modela i metrika propusnosti za dvije različite pokazne naprave – miša i grafički tablet. Dodatno, provedena je i odgovarajuća provjera valjanosti modela, također zasnovana na eksperimentalnim zadacima sa stvarnim korisnicima. Pokazano je kako predloženi model predviđa vrijeme izvođenja zakrivljene trajektorije uz metriku pogreške RMSPE s najvećom vrijednošću 10.61%.
Abstract (english)
In the field of Human-Computer Interaction (HCI), in addition to point-and-select actions, steering tasks are often formalized, which include performing a curved trajectory, i.e. steering the cursor through the corresponding tunnel. Along the motivational basis in Fitts’ law, and given the specifics of the curve drawing task, this thesis proposes and argues a model for calculating the index of difficulty of the task and estimating the time required to perform such a task. Based on the theoretical foundations of the proposed predictive model, the HCI experiment was conducted in order to extract specific versions of the model and throughput metrics for two different pointing devices – a mouse and a graphics tablet. In addition, an appropriate model validation was carried out, also based on experimental tasks with real users. It is shown that the proposed model predicts the curve drawing time with RMSP E error metric with a maximum value of 10.61%.
