Robot Vision
Published in Bogdan M. Wilamowski, J. David Irwin, Control and Mechatronics, 2018
The first example is a robot/camera “hand–eye” coordination task in which a robotic manipulator is used to pick up identified objects from a table or shelf and carrying out some manipulation task on them, whether sorting, rearranging or retrieving them to assist a disabled person. As an example (Figure 37.2), a color camera and a rangefinder collect color intensity and range data in registered 2D arrays, which collectively result in a 2 1/2D representation of the 3D scene of the pile of objects to be dealt with. A database describing the types of objects likely to be encountered in terms of structure, geometry, and surface appearance is available. It is also possible that specific objects be identified once their detailed characteristics have been extracted. This latter task can be achieved using, among other methodologies, a scale-invariant feature transform (SIFT) algorithm that extracts a number of very localized features for marking purposes, where each set of such features essentially captures “a signature” of a specific object. While the SIFT approach can match specific details between two images taken from different viewpoints or between a viewed object image and the image of the same (or identical) object collected in a database of many images of various objects, thus being able to identify it, generic objects (e.g., cups or apples) can not be directly recognized in this way because shape information has not been processed.
A study of the image of e-Sports in the Chinese newspapers

There has been no common specific academic definition for e-Sports (Electronic sports) so far. Since the only difference between e-Sports and online games is competition. Thus, the concept must be elaborated in order to distinguish e-Sports as not simply playing video games and that e-Sports is an intellection competition between people using electronic software and hardware devices. Through exercise, you can train and improve the participants’ cognitive ability, responsiveness, hand-eye coordination, determination and teamwork. In fact, like any other sports, e-Sports is just as focused on professionalism, with emphasis on the physical and mental exercise and teamwork. There are still quite a lot of differences between e-Sports and cyber games.
Physical Development
Published in Krystina Castella, Designing for Kids, 2018
To develop motor skills, children need the time, space and opportunity to move their bodies in big ways and small. Physical movement, dancing and active play provide opportunities for gross motor skill development. Dexterity toys and constructive and creative play provide opportunities for fine motor skill development. Digital play provides opportunities for developing hand–eye coordination when children visually follow an object on the screen. Hand–eye coordination is essential as children begin school, when they learn how to use their hands and eyes while writing and drawing.

Hand-eye coordination is the synchronization and regulation of eye and hand movement. It also has visual data to assist in reaching and grasping using hand proprioception to guide the eyes [2]. Between four and fourteen months, hand-eye coordination is developed. Infants explore their surroundings and develop hand-eye coordination with fine motor abilities. Fine motor skills are engaged in the control of muscle action because when a child begins to use his or her fingers to pick the object, he/she does the same in combination with his or her eyes [3].
