FR2788151A1 - Mobile phone mouse converter for display screen for interpretation of maps has phone used as a mouse for movement over the map - Google Patents

Abstract

The mouse converter for a mobile telephone has an activation button (1) with displacement sensors that produce signals proportional to the displacement in directions X and Y of the display. A circuit modifies the graphical information of the portable machine and displays the information. There is a memory for the data (6) representative of all or part of the graphical information. If the machine is moved in the X or Y directions the machine acts as a simple window or opening when it is moved upwards along the Z axis it acts as a magnifying glass.

Description

-1 - The present invention relates to a display control device

  which allows you to make a change in the display of graphic information. It is intended to be integrated into a portable machine

  comprising one or more display means.

  State of the prior art: To interact with a graphic object present on a display means,

  a mouse, wheels or keyboard are commonly used.

  The present invention requires only one button and allows

  instinctive approach to interaction with the portable machine.

Description of the invention

  According to the invention, the graphic information display control device intended to be integrated into a portable machine provided with display means is characterized in that it comprises:

  - A means of activating the system.

  - One or more displacement sensors for delivering signals representative of the displacements of the display means in at least the X and Y directions. - Means for modifying the portion of the graphic information displayed as a function of the signals delivered by the said sensor (s) to the less in X and Y, to receive graphical information from the portable machine system and to transmit this modified information to the system

  display of the portable machine.

  - Storage means for data representative of the whole

  or part of the said graphic information, or of necessary data

  the functioning of the system.

  The present invention is described with reference to the appended figures in which: - Figure 1 shows schematically the circuits of the control device; and - Figure 2 shows in perspective a portable machine

  any one equipped with the control device.

  -2- We will describe a particular embodiment of the invention in which the graphic information corresponds to a geographic map

  and the machine to a cell phone. However, it goes without saying that the information

  graphic mations can be of any kind like a text or an image or any object which we want to make appear parts on a

  display means, and the machine of any kind also.

  Screen 7 of telephone 8 defines the plane X, Y.

  This device according to the description is characterized in that the part

  of graphical information displayed has fixed dimensions corresponding to those of the display means, and in that the modification of the part of the graphical information displayed consists of a translation in X and in Y

  according to the signals delivered by said sensors.

  If the button 1 is not pressed, the displayed object is fixed relative to the screen 7. If the button 1 is pressed, the system of the invention is activated: a displacement sensor 2 secured to the screen 7 generates the data X, Y of the movement of the telephone 8 in

  physical space, which are transmitted to the computer 3.

  This modifies the object display information from system 4 of telephone 8 and routes it to the display system 5 of telephone 8. When the system is activated, the object displayed on the screen is immobilized in the user's repository, which allows him to move the screen over the displayed and immobile object, in the manner of a mobile skylight, so that he can browse it partially or entirely,

  for example to follow a path on a map.

  Block 2 of the control device can be composed of a displacement sensor delivering three signals X, Y, Z, or three sensors delivering

  each a signal. Block 3 of the description is a calculation unit, it

  receives signals from the sensor (s), and it is connected to systems 4 and 5 of the portable machine by at least two links, so as to receive the data and transmit the modified data. One or more additional links between block 3 and any part of the machine 8 can be used to convey control signals intended for

  internal machine functions other than display.

  The block 3 is also connected to a storage means 6 so as to

  ability to read or write data to it.

3- 2788151

  In other words, and in the particular example considered, the storage means 6 contain all of the data corresponding to

  the entire map you want to display.

  For a given position of the control device, the system selects the data relating to the part of the card considered. This data is used to display this part of the map on screen 7. The displacement of the device in X and / or in Y detected by the sensor (s) 2 causes the modification of the selected data and therefore the

  modification of the part of the card appearing on the screen.

  We can distinguish other particular embodiments of the invention: Preferably, said sensors also deliver a signal representative of the movements of said machine in direction Z orthogonal to directions X and Y and in that said modification of the part graphical information displayed consists of a homotethy whose ratio is a function of the signal delivered by the sensors in the Z direction, whereby the displayed image corresponds to a modified part of the information corresponding to

  a modified scale occupying the entire surface of said display means.

  By approaching or moving the screen away from his eyes, the user can therefore vary the scale of the displayed object, like a magnifying glass, which allows him, for example, to increase the legibility of small characters , by showing only a reduced part of the map on the screen, therefore by increasing the scale, or on the contrary by increasing the part

  displayed from the map to the screen, therefore by reducing the scale of this map.

  In all cases, the displayed image occupies on the screen the entire surface which

  reserved for him by the machine 8.

  - Preferably, according to an embodiment which employs acceleration sensors to acquire the data X, Y, Z, these data are processed by a calculation unit using an algorithm to extract the

  influences of the force of gravitation.

  The modified data X, Y, Z then characterize only the translations of the machine (8), and the system becomes insensitive to the inclinations of the machine (8) which could result in

  parasitic movements of the displayed object.

  -4- - Preferably, the device according to the invention comprises software or hardware adjustment means acting on a calculation unit 3 to adjust the range of movements necessary for a complete variation of the object displayed on the display means . - Preferably, in the device according to the invention, a calculation unit compares the evolution of the data X, Y, Z with that of sequences stored in a memory to, in the event of a match, send signals to the portable machine 8 for internal functions

  other than the display ones.

  - Preferably, in the device according to the invention, several or all the components of the system are integrated into a single circuit performing several or all of the functions defined above, this single circuit can also be, for example, one of the circuits of

  the machine 8 in which the invention has been integrated.

  If this circuit of the machine 8 already has data storage means, a part of these means can for example be assigned to the

  operation of the control device.

  If this circuit of the machine 8 already has computing means, part

  of these means can for example be assigned to the functioning of the

positive order.

  This is to minimize the number of circuits required by the control device, by increasing the sharing of tasks between the

components already present.
