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.
