3. 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.
4. 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?
6. WHATS HOLOGRAM
Holography 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.
7. DEVELOPMENT IN
HOLOGRAPHY
In 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
8. HOLOGRAM SYNTHESIS
MOST 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.
11. HOLOGRAPHIC SENSOR
A
holographic sensor i
s a device that
comprises
a hologram embedd
ed 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
12. 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.
13. 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
14. INTERACTIVE PROJECTOR
Holographic 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.
15. INTERACTIVE PROJECTOR
Virtual 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.
16. If Holographic Projection is implemented
successfully many touch screen such as one we
seen in “Iron Man” movie can be implemented.
