Abstract: A board is made of many grid points (1 and 2) arranged in a grid on a flat surface (6), and connected to a game manager (3) (a CPU+memory+software). Each grid point notifies the games manager when it is pressed, and the games manager can illuminate each grid point by one of two colors. The boards play a game in which the game starts with an equal number of points illuminated in each of the two colors. Each player in their turn presses a point, and in response the games manager switches of some points (possibly none) and potentially changes the color of some other points. When all the points that are illuminated are illuminated in the same color, the player of this color wins.

Abstract: A hand-writing practicing system is comprised of a computer with a screen that can sense the movement of a stylus on it, and software the displays to the user original script in hand-writing, record the stylus movement as user-writing and display it on top of the original script.

Abstract: A board is made of many grid points 1 & 2 arranged in a grid on a flat surface 6, and connected to a game manager 3 (a CPU+memory+software). Each grid point notifies the games manager when it is pressed, and the games manager can illuminate each grid point by one of two color. The boards plays a game in which a point is a legal move if its ‘visibility’ for the player is above or equal some value. The ‘visibility’ of a point is determined by checking in turn each of a predefined set of imaginary straight lines emanating from the point. If the line does not pass through any illuminated point, it is assigned a value of 0. Otherwise the line is assigned a value of 1 if the closest illuminated point that it passes through is illuminated in the colour of the player, or ?1 if it is in the opponent's color. The sum of the values of the lines is the ‘visibility’ of the point for the player.

Each grid point notifies the games manager when it is pressed, and the games manager can illuminate each grid point by one of two color. The board plays a game in which each player in his turn presses a point which causes a pattern of points around this point to be switched on with the player color if they were off, or reverse their color if they were on. The winner is the player that has more points when all the points are switched on.

Abstract: A boar is made of many points arranged in a grid on a flat surface, and connected to a game manager (a CPU+memory+software). Each grid point notifies the games manager when it is pressed, and the games manager can illuminate each grid point by one of the colours. The board moves a sound the grid a group of points in one colour, and the players try to touch it.

Abstract: A grid of points is constructed from the following four layers: A transparent membrane keyboard with a press-sensitive area at each grid point A layer of a uniform, translucent material below the membrane keyboard. A separation layer of opaque material below the translucent layer, which for each grid point has a circular hole with reflecting or very light walls. A PCB below the separation layer, on which two or more light sources per grid point are mounted, and also carries the circuitry to drive them. The four layers are held together, and the thickness of the separation layer is such that the light sources are not immediately below the translucent area, but some distance away. The membrane keyboard and the control of the light sources are both connected to a CPU with some memory which uses them to manage various games and puzzles.

Abstract: A board is made of many grid points (1 and 2) arranged in a grid on a flat surface (6), and connect to a game manager (3) (a CPU+memory+software). Each grid point notifies the games manager when it is pressed, and the games manager can illuminate each grid point by one of two color. Every fixed period of time (generation) the games manager checks for each point the illumination state of the point and of a pattern of points around it, and accordingly decides what will be the illumination state of the point in the next generation. The player(s) can also affect the illumination state of a point by pressing it, and the task of the player(s) is to keep some points illuminated as long as possible, cause all the points to be switched off as fast as possible, or cause all illuminated points to be only in one color.
