Visual Optics: Accommodation in a Splash
نویسنده
چکیده
Gannets are large seabirds that hunt fish from the air, making a plunge dive followed by active swimming pursuit of prey. A recent study shows that they convert from aerial to aquatic vision nearly instantly.

Characterizing the Parallel Execution Behavior of some SPLASH-2 Applications on Multiprocessors
In order to evaluate the benefits of parallel systems, it is necessary to know how real parallel programs behave. The SPLASH-2 applications provide us with a realistic workload for such systems. We have instrumented the PARMACS macros used by SPLASH-2 applications in order to study their parallel behavior, focusing on the overhead introduced by synchronization and parallelism management. The in...
متن کاملGate Me If You Can
Current free-to-play mobile games use various mechanics to control player progression. Through the game Jelly Splash, we study three such gating mechanics: occasional spikes in level difficulty, chapter gates every 20 levels, and a limited number of lives regenerating slowly over time. Using telemetry data from a quarter-million players, we explore how players approach each gating mechanic, foc...
متن کاملEvaluation of ocular accommodation, convergence and fusional vergence changes during Ramadan
Purpose: There are a few researches regarding the effects of Islamic fasting on visual system. The aim of this study was to investigate the effects of Ramadan fasting on the amplitude of accommodation (AA), near point of convergence (NPC), positive and negative fusional vergences (PFV and NFV, respectively) in visually healthy fasters. Methods: AA, NPC, PFV and NFV at far (6m) and near (40cm) w...
متن کاملTheoretical Considerations on Compensation of the Accommodation-Vergence Mismatch by Refractive Power of Focus-Adjustable 3D Glasses
The accommodation-vergence mismatch has been considered as a cause of the visual fatigue induced in watching 3D display. We would propose the mismatch can be compensated by refractive power of adjustable-focus 3D glasses. From lens optics and geometrical considerations, we also developed equations that calculate required refractive power of the 3D glasses. The compensation we proposed is suppos...
متن کاملOn the possibility of intraocular adaptive optics.
We consider the technical possibility of an adaptive contact lens and an adaptive eye lens implant based on the modal liquid crystal wavefront corrector, aimed to correct the accommodation loss and higher-order aberrations of the human eye. Our first demonstrator with 5 mm optical aperture is capable of changing the focusing power in the range of 0 to +3 diopters and can be controlled via a wir...
