Milner and Goodale described a model which distinguishes between two visual streams in the brain. It is claimed that the ventral stream serves object recognition (i.e. vision for perception), and the dorsal streams provides visual information for the guidance of action (i.e. vision for action). This model is supported by evidence from the domain of spatial vision, but it remains unclear how mot...

Animal research often relies on catching wild animals; however, individuals may have different trappability, and this can generate bias. We studied bias in mist netting, the main method for catching wild birds. The unusually high resighting rate in our study population-house sparrows (Passer domesticus) on Lundy Island (England)-allowed us to obtain accurate estimates of the population size. Th...

This paper presents the current progress on a trajectory estimation of a flying object for a robotic catching system, using general purpose and readily available hardware. A recursive least squares (RLS) algorithm is used to extract and predict the position of a flying object in a 3D environment with the information gathered from only one camera.

To catch or grasp an object, the initiation of hand closure has to be coordinated with the relative movement between hand and object. In search of a common control of the initiation of hand closure for both tasks (van de Kamp, Bongers, & Zaal, 2010), the authors studied two tasks, catching while keeping the hand stationary and prehension. They showed that the initiation of hand closure could we...

Two experiments were conducted in order to investigate the adaptability and associated strategies of the human perceptuo-motor system to deal with changing constraints. In a catching task, perceptual-motor constraints were internally controlled by coupling movement onset of the catch and the illumination circuit in the lab: upon the first movement of the catcher, all lights went out within 3 ms...
