computing a movement of the handheld laboratory device from the acceleration data;

transmitting the computed movement from the handheld laboratory device to a display device remote from the handheld laboratory device;

comparing the computed movement with a predetermined set of movements, where the computed movement matches or is similar to one of the predetermined set of movements;

initiating a screen navigation function corresponding to the matched predetermined movement;

transmitting a control function corresponding to the screen navigation function from the display device to the handheld laboratory device; and

initiating a control function in the handheld laboratory device via the screen navigation function.

2. A display device comprising a screen,

the display device being

remote from a handheld laboratory device and operable to perform a measurement on the handheld laboratory device by

comparing a computed movement with a predetermined set of movements, where the movement matches or is similar to one of the predetermined set of movements;

initiating a screen navigation function corresponding to the matched predetermined movement on a display device remote from the handheld laboratory device;

initiating a control function in the handheld laboratory device via the screen navigation function, wherein the computed movement is computed by the handheld laboratory device;

recording acceleration data from an accelerometer of the handheld laboratory device; and

computing a movement of the handheld laboratory device from the acceleration data.

3. A display device according to claim 2 , comprising at least one position sensor and an accelerator, wherein the display device is operable to use the movement or acceleration of the display device for computing the movement of the handheld laboratory device.

4. A handheld laboratory device comprising measurement means and at least one accelerometer, and a wireless transmitter, wherein

the measurement means are operable by recording acceleration data from the accelerometer corresponding to a movement of the handheld laboratory device by a user;

computing a movement of the handheld laboratory device from the acceleration data;

transmitting the computed movement from the handheld laboratory device to a display device remote from the handheld laboratory device; and receiving from the display device initiation of a control function,

wherein the display device is operable by comparing the computed movement with a predetermined set of movements, where the computed movement matches or is similar to one of the predetermined set of movements; initiating a screen navigation function corresponding to the matched predetermined movement; and transmitting a control function corresponding to the screen navigation function from the display device to the handheld laboratory device.

5. A handheld laboratory device according to claim 4 , wherein the measurement means comprise one or more of a photometer, a spectrometer, a pH meters, a volt, conductivity or ampere meter; a luminometer, a gas detection meter, a pipette, a turbidity meter, a nephleometer, a temperature or pressure meter, a x-ray detection meter, a scanners for drugs or explosives, a glucose meter, a biosensor, a point of care diagnostic device, a blood pressure meter, or mixtures thereof.

6. A method of operating a handheld laboratory device, the method comprising the steps of

recording acceleration data from an accelerometer of the handheld laboratory device corresponding to a movement of the handheld laboratory device by a user;

computing a movement of the handheld laboratory device from the acceleration data;

transmitting the computed movement from the handheld laboratory device to a display device remote from the handheld laboratory device;

comparing the computed movement with a predetermined set of movements, where the computed movement matches or is similar to one of the predetermined set of movements;

initiating a screen navigation function corresponding to the matched predetermined movement;

transmitting a control function corresponding to the screen navigation function from the display device to the handheld laboratory device; and

initiating a control function in the handheld laboratory device via the screen navigation function.

7. A method according to claim 6 , comprising computing the movement of the handheld laboratory device by computing a trajectory of the movement of the handheld laboratory device.

8. A method according to claim 7 , comprising comparing the computed trajectory with predetermined movements or trajectories to match the computed trajectory with one predetermined movement.

9. A method according to claim 6 , comprising receiving acceleration or movement data from at least one of a position sensor and an accelerator of the display device, and using the movement or acceleration of the display device in computing the movement of the handheld laboratory device.

10. A method according to claim 6 , wherein the predetermined movements are one or more of a tilting movement, movements away or towards the user, movements to the right or left of the user, movements up and down, circular movements clockwise or anti clockwise, spinning movements clockwise or anti clockwise, shaking movements, no movement (still stand), or a combination thereof.

11. A method according to claim 6 , comprising computing the movement of the handheld laboratory device relative to the handheld laboratory device or relative to the user or relative to a fixed coordinate system in space.

12. A method according to claim 6 , wherein the screen navigation functions are one or more of scrolling of a screen, opening a new screen, selecting a function or a tap on a screen, tapping a tap, browsing through a sequence of taps or functions for selection, switching to cursor movement and back, editing a screen, starting a program, closing a program, and login on or off of a user.

13. A method according to claim 6 , wherein the control function in the handheld laboratory device is to switch the device on or off, start a measurement, stop a measurement, send data to the display device, switch on or of a light source, switch on or of a sensor, switch on or of an indicator light, determine the status of a button, receive data from the display device, display information on a display in the handheld device, send battery status information, send error messages, and mixtures thereof.
