Towards an optimal decision strategy of visual search
Searching for objects amongst clutter is a key ability of visual systems. Speed and accuracy are often crucial: how can the visual system trade off these competing quantities for optimal performance in different tasks? How does the trade-off depend on target appearance and scene complexity? We show that the optimal tradeoff strategy may be cast as the solution to a partially observable Markov d...
متن کاملAdaptive but non-optimal visual search behavior with highlighted displays
Previous research has suggested that making certain items visually salient, or highlighting, can speed performance in a visual search task. But designers of interfaces cannot always easily anticipate a user’s target, and highlighting items other than the target can be associated with performance decrements. An experiment performed suggested that people attend to highlighting less than what an o...
متن کاملA bayesian optimal foraging model of human visual search.
Real-world visual searches often contain a variable and unknown number of targets. Such searches present difficult metacognitive challenges, as searchers must decide when to stop looking for additional targets, which results in high miss rates in multiple-target searches. In the study reported here, we quantified human strategies in multiple-target search via an ecological optimal foraging mode...
متن کاملOptimal Eye Movement Strategies in Visual Search (Supplement)
Here we derive the ideal searcher for the case of dynamic (temporally uncorrelated) external and internal noise, and we describe (without proof) the ideal searcher for the case of static (temporally correlated) external noise and dynamic (temporally uncorrelated) internal noise. As a check on the accuracy of the formulas for these ideal searchers, they were derived via two separate methods: a d...
متن کاملSimple summation rule for optimal fixation selection in visual search
When searching for a known target in a natural texture, practiced humans achieve near-optimal performance compared to a Bayesian ideal searcher constrained with the human map of target detectability across the visual field [Najemnik, J., & Geisler, W. S. (2005). Optimal eye movement strategies in visual search. Nature, 434, 387-391]. To do so, humans must be good at choosing where to fixate dur...
