EMBEDDED EVERYWHERE

EMBEDDED IN MOBILE TECHNOLOGY

An embedded system has electronics – both digital and analog, special purpose sensors and actuators, software, mechanical items etc., and with design challenges of space, weight, cost and power consumption.

Present Technology For past 10 years keyboards

and touch screen where used for input in smart phones. Evolution from keyboard to touch screen made a remarkable changes to the mobile phone. So now what is next?

WHATS NEXT??

INCORPORATING HOLOGRAM PROJECTION WITH MOBILE TECHNOLOGY

HOLOGRAPHIC PROJECTION IN MOBILES

WHATS HOLOGRAMHolography is a

technique which enables three-dimensional images to be made. It involves the use of a laser, interference, diffraction, light intensity recording and suitable illumination of the recording.

DEVELOPMENT IN HOLOGRAPHYIn principle, it is

possible to make a hologram for any wave.

Electron holography◦ techniques to electron

waves Acoustic holography

◦ the sound field near a source

Atomic holography ◦ basic elements of atom

optics

HOLOGRAM SYNTHESISMOST COMMON METHODS IN

HOLOGRAM SYNTHESIS:◦DIRECT ANALYTIC MODELING◦FOURIER-BASED MODELING

FRESNEL TRANSFORM: The calculation of a Fresnel transform can be

mathematically performed as a Fourier transform and multiplication with quadratic phase factors. The discrete Fourier transform can be efficiently executed by using the fast Fourier transform (FFT) algorithms.

HOLOGRAPHIC SENSORA

holographic sensor is a device that comprises a hologram embedded in a smart material that detects certain molecules or metabolites.

A holographic sensor aims to integrate the sensor component, the transducer and the display in one device for fast reading of molecular concentrations based in colorful reflections or wavelengths

HAPTIC SENSOR:◦to create tactile feedback is to attach

physical devices to a person's hands or body, though this can interfere with the illusion of touching a hologram.

◦A tactile feedback technology takes advantage of the sense of touch by applying  forces, vibrations, or motions to the user.

HAPTIC TECHNOLOGY HOLOGRAPHIC INTERACTION

Allows the user to interact with a hologram and receive tactile responses. The research uses ultrasound waves to create acoustic radiation pressure, which provides tactile feedback as users interact with the holographic object. The haptic technology does not affect the hologram, or the interaction with it, only the tactile response that the user perceives.

INTERACTIVE PROJECTORHolographic projecting mobile phones

will incorporate a powerful processor which will take a 2D image and then create 3D holograms by way of using “Fourier” algorithms to give them a third dimension without resolution loss.

INTERACTIVE PROJECTORVirtual holographic

projection imaging technique make use of interference and diffraction theory. It record and reproduce objects in real three-dimensional image

Haptic sensors are embedded along the device.

If Holographic Projection is implemented successfully many touch screen such as one we seen in “Iron Man” movie can be implemented.

HI-TECH FUTURE DREAM

HAPPY FUTURE AWAITS FOR US.
