1. Method of transmitting tactile information to a touch plate (10) of a tactile display containing tactile pads (11), said touch plate (10) being controlled by a server (54, 64, 74), and in this method,(a) tactile information transmitted in the form of a digital word is defined as being a sequence of a predefined number of images together forming a pattern, each image having a rank in the pattern, each pattern being defined by:
- a design of successive images, the designs corresponding to a first and to a second image being identical to each other if the tactile pads in the first design and the tactile pads in the second design in the same geographic position in each of the first and the second images are in the same state, and being distinct from each other if they are not in the same state,a duration for each image as a function of its rank in the sequence of images,a duration between successive consecutive images,a duration between consecutive patterns;
(b) said word is transmitted to a tactile display server (54, 64, 74), preceded by a beacon indicating that data following the beacon must be directed to the touch plate control server;
(c) a series of instructions is activated when the tactile display server receives the word, this series having a start address that depends on said word, said series of instructions being used to display the successive images together forming the pattern corresponding to the word to be displayed, said series of instructions being repeated to display the same pattern a predefined number of times or for a predetermined duration.

Abstract
Method of transmitting tactile information to a tactile display with a touch plate containing pads, the touch plate being controlled by a server, in which,
- (a) tactile information is defined as being a sequence of a predefined number of images together forming a pattern, each image having a rank in the pattern, each pattern being defined by:
- a design of successive images
- a duration for each image,
- a duration between consecutive images,
- a duration between consecutive patterns;
- (b) said word is transmitted to a tactile display server, preceded by a beacon indicating that data following the beacon must be directed to the touch plate control server;
- (c) a series of instructions is activated when the server receives the word, this series having a start address that depends on said word, said series of instructions being used to display the successive images together forming the pattern corresponding to the word to be displayed, said series of instructions being repeated to display the same pattern a predefined number of times or for a predetermined duration.
- (a) tactile information is defined as being a sequence of a predefined number of images together forming a pattern, each image having a rank in the pattern, each pattern being defined by:

8. Tactile display comprising,
a touch plate (10), with a touch area (1) on which tactile pads (11), are arranged, the tactile pads (11) being capable of several tactile states distinct from each other, including a so-called neutral state, a network of magnetic coils (31) activating the tactile pads (11), as a function of currents circulating in said coils (31) to produce a tactile feel on the touch area (1) that is a function of the different currents circulating in each of said coils (31), at least one addressing circuit (4) selectively addressing currents in the different coils (31), a control server (54, 64, 74) being equipped with a software module (57, 67, 77) to translate an individual global command among a plurality of possible individual global commands into a series of values and natures of electrical signals to be addressed to each magnetic coil (31) through the addressing circuit (4), this series of values and natures of electrical signals being a function of each individual global command and conferring a state to each pad (11), the different states of the different pads (11) forming a design on the touch plate (10), said design being unchanged either for a predetermined duration at the end of which all pads (11) will return to the neutral state, or for a duration that terminates when a new command is received, the pads (11) then changing state to take on the state resulting from said new global command and to form a new design, the server comprising an information connection (55, 65, 75) to the tactile display wherein said software module (57, 67, 77) also comprises instructions to keep the first design for a predetermined duration, to renew the first design and to replace it by a second design different from or identical to the first design after returning to the neutral state for a predetermined positive or zero duration, and so as far as a last design different from or identical to a last but one design, the series of designs being timed such that the duration of each design and the duration separating the designs of consecutive ranks forming a series of images, the series of images forming a pattern, and the software module (57, 67, 77) also comprising instructions to repeat the pattern thus formed a predetermined number of times or for a predetermined duration, at inter-pattern time intervals (TIM) with an arbitrary positive duration or a duration equal to a duration between consecutive designs in a pattern.
