A system and method for forming a micro-object density distribution (how densely micro-objects are assembled in a particular spatial region) are provided. [Solution] A high-speed camera tracks the existing object density distribution. An array of phototransistor-controlled electrodes is used to generate a dynamic potential energy terrain for manipulating objects with both DEP and EP forces, and a video projector is used to actuate the array. One or more computing devices are used to process images captured by the camera, estimate the existing density distribution of objects, receive a desired density distribution of micro-objects, define a model that describes the variation in micro-object density over time due to capacitance-based interactions, generate an array of electrode potentials that minimizes the error between the existing density distribution and the desired density distribution, and use the array of electrode potentials to actuate the electrodes.

The present invention (also referred to as “method and system for displaying ball placement location in screen golf or hybrid golf game”) is a technology that implements a teeing area and ball location for each hole to enable exercise in conjunction with actual golf and indoor screen golf, including an omitted section from the teeing ground to a point before the landing point of the second or third ball, and obstacles such as the actual green and surrounding bunkers, rough, and hazards in indoor and outdoor hybrid golf. The invention relates to a golf system that displays the landing position of a ball on the teeing ground of an indoor or outdoor practice range using a laser beam (which is also referred to as “a ball placement position at a corresponding location using a laser projection device, video projector, or holographic display device, by converting virtual ball landing point coordinates calculated based on the player’s shot result into actual playing space coordinates) and to the design and method of use thereof. The present invention provides a virtual-reality linked golf interface technology that specifies the position of a player's subsequent shot by synchronizing the results of a virtual golf simulation with the physical coordinates of an actual playing space.

An entertainment device for a swimming pool comprises a housing that accommodates a video projector capable of casting at least one image onto a bottom of the swimming pool. The housing is provided with a circuit for cooling the video projector and / or electrical and / or electronic components accommodated inside the housing. The entertainment device comprises a fastening device comprising at least two fastening links.

An electronic apparatus includes: a video projector; a first sensor; a second sensor; a memory; and at least one processor. The at least one processor is configured to: acquire projection distance information to a projection surface based on sensing data acquired through the first sensor, acquire illuminance information based on the sensing data acquired through the second sensor, acquire gain information for each region included in the projection surface based on the projection distance information and the illuminance information, correct the gain information for each region based on correlation information between the projection distance information and image quality information and correlation information between the illuminance information and the image quality information, acquire an output video by correcting the input video based on the corrected gain information for each region, and control the video projector to project the output video onto the projection surface.
