Epoch Game Pocket Computer
The is a second-generation handheld game console released by Epoch Co. in Japan in 1984 for 12,800 Japanese yen. It is also known as ''Pokekon'' and was one of the very few truly handheld systems to be released in the early 1980s, preceding the Game Boy by 5 years. The system was a commercial failure in Japan, and as a result, only 5 games were made for it. A puzzle game and a paint program were built into the system. It was powered by 4 AA batteries, and screen's contrast could be adjusted by the user. Input and output controls included four buttons, an 8-way joypad, a contrast dial, and a sound on-off switch. Because the Game Pocket Computer failed in Japan, and was never released internationally, the device is extremely rare, and units on eBay can go for hundreds of US dollars.

Epoch Co
In chronology and periodization, an epoch or reference epoch is an instant in time chosen as the origin of a particular calendar era. The "epoch" serves as a reference point from which time is measured. The moment of epoch is usually decided by congruity, or by following conventions understood from the epoch in question. The epoch moment or date is usually defined from a specific, clear event of change, an ''epoch event''. In a more gradual change, a deciding moment is chosen when the ''epoch criterion'' was reached. Calendar eras Pre-modern eras * The Yoruba calendar (''Kọ́jọ́dá'') uses 8042 BC as the epoch, regarded as the year of the creation of Ile-Ife by the god Obatala, also regarded as the creation of the earth. * ''Anno Mundi'' (years since the creation of the world) is used in the Byzantine calendar (5509 BC). * ''Anno Mundi'' (years since the creation of the world) as used in the Hebrew calendar (3761 BC). * Olympiads, the ancient Greek era of four-year ...

Handheld Game Consoles
A handheld game console, or simply handheld console, is a small, portable self-contained video game console with a built-in screen, game controls and speakers. Handheld game consoles are smaller than home video game consoles and contain the console, screen, speakers, and controls in one unit, allowing people to carry them and play them at any time or place.Li, Frederick W. B. Computer Games'. . Durham University. Retrieved December 19, 2008. p. 4. In 1976, Mattel introduced the first handheld electronic game with the release of ''Auto Race''. Later, several companies—including Coleco and Milton Bradley—made their own single-game, lightweight table-top or handheld electronic game devices. The first commercial successful handheld console was Merlin from 1978 which sold more than 5 million units. The first handheld game console with interchangeable cartridges is the Milton Bradley Microvision in 1979. Nintendo is credited with popularizing the handheld console concept w ...

Barcode Battler
The is a handheld game console released by Epoch Co. in March 1991. The console at retail was supplied with a number of cards, each of which had a barcode. Upon starting the game, the player must swipe a barcode representing a player. The game uses barcodes to create a character for the player to use. Not all barcodes work as players; instead some represent enemies or powerups.Conveni Wars Barcode Battler Manuals バーコードバトラー'. Epoch, Co. pp.1-14. 1991. Because of the ubiquity of barcodes in daily life, players were encouraged to go beyond the barcodes provided with the game itself and to experiment to find their own barcode monsters and powerups from everyday products like food and cleaning products. Once the game itself is started, the characters "battle" against each other. The characters' statistics were applied to an algorithm containing a random number generator to determine the outcome of each round in the fight. History The original Barcode Battler was r ...

Sokoban
is a puzzle video game in which the player pushes boxes around in a warehouse, trying to get them to storage locations. The game was designed in 1981 by Hiroyuki Imabayashi, and first published in December 1982. Gameplay The game is played on a board of squares, where each square is a floor or a wall. Some floor squares contain boxes, and some floor squares are marked as storage locations. The player is confined to the board and may move horizontally or vertically onto empty squares (never through walls or boxes). The player can move a box by walking up to it and push it to the square beyond. Boxes cannot be pulled, and they cannot be pushed to squares with walls or other boxes. The number of boxes equals the number of storage locations. The puzzle is solved when all boxes are placed at storage locations. Selected official releases Development ''Sokoban'' was created in 1981 by Hiroyuki Imabayashi. The first commercial game was published in December 1982 by Thinking Rabbit, ...

Reversi
Reversi is a strategy board game for two players, played on an 8×8 uncheckered board. It was invented in 1883. Othello, a variant with a fixed initial setup of the board, was patented in 1971. Basics There are sixty-four identical game pieces called ''disks'', which are light on one side and dark on the other. Players take turns placing disks on the board with their assigned color facing up. During a play, any disks of the opponent's color that are in a straight line and bounded by the disk just placed and another disk of the current player's color are turned over to the current player's color. The objective of the game is to have the majority of disks turned to display one's color when the last playable empty square is filled. History Original version Englishmen Lewis Waterman and John W. Mollett both claim to have invented the game of Reversi in 1883, each denouncing the other as a fraud. The game gained considerable popularity in England at the end of the 19th century ...

Mahjong
Mahjong or mah-jongg (English pronunciation: ) is a tile-based game that was developed in the 19th century in China and has spread throughout the world since the early 20th century. It is commonly played by four players (with some three-player variations found in parts of China, Japan, South Korea and Southeast Asia). The game and its regional variants are widely played throughout East and Southeast Asia and have also become popular in Western countries. The game has also been adapted into a widespread online entertainment. Similar to the Western card game rummy, Mahjong is a game of skill, strategy, and luck. To distinguish it from mahjong solitaire, it is sometimes referred to as mahjong rummy. The game is played with a set of 144 tiles based on Chinese characters and symbols, although many regional variations may omit some tiles or add unique ones. In most variations, each player begins by receiving 13 tiles. In turn, players draw and discard tiles until they complete ...

Raster Graphics Editor
A raster graphics editor is a computer program that allows users to create and edit images interactively on the computer screen and save them in one of many raster graphics file formats (also known as bitmap images) such as JPEG, PNG, and GIF. Comparison to vector graphic editors Vector graphics editors are often contrasted with raster graphics editors, yet their capabilities complement each other. The technical difference between vector and raster editors stem from the difference between vector and raster images. Vector graphics are created mathematically, using geometric formulas. Each element is created and manipulated numerically; essentially using Cartesian coordinates for the placement of key points, and then a mathematical algorithm to connect the dots and define the colors. Raster images include digital photos. A raster image is made up of rows and columns of dots, called pixels, and is generally more photo-realistic. This is the standard form for digital came ...

Fifteen Puzzle
The 15 puzzle (also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square and many others) is a sliding puzzle having 15 square tiles numbered 1–15 in a frame that is 4 tiles high and 4 tiles wide, leaving one unoccupied tile position. Tiles in the same row or column of the open position can be moved by sliding them horizontally or vertically, respectively. The goal of the puzzle is to place the tiles in numerical order. Named for the number of tiles in the frame, the 15 puzzle may also be called a 16 puzzle, alluding to its total tile capacity. Similar names are used for different sized variants of the 15 puzzle, such as the 8 puzzle that has 8 tiles in a 3×3 frame. The ''n'' puzzle is a classical problem for modelling algorithms involving heuristics. Commonly used heuristics for this problem include counting the number of misplaced tiles and finding the sum of the taxicab distances between each block and its position in the goal configuration. Note that both are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges. Acoustics Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an ''acoustician'', while someone working in the field o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
