• Interference occurs when one or more wavefronts are superimposed. Diffraction occurs whenever a wavefront encounters an object.
• ### holographic mobile

1. 1. EMBEDDED EVERYWHERE
2. 2. 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.
3. 3. 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?
4. 4. WHATS NEXT??  INCORPORATING HOLOGRAM PROJECTION WITH MOBILE TECHNOLOGY HOLOGRAPHIC PROJECTION IN MOBILES
5. 5. 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.
6. 6. 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
7. 7. 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.
8. 8. FUTURE MOBILE TECHNOLOGY  HOLOGRAPHIC PROJECTOR.  VIRTUAL TOUCH SCREEN
9. 9. REQUIREMENTS FOR HOLOGRAPHIC MOBILES  MOBILE COMPUTER  HOLOGRAM  SENSOR  DISPLAY MEDIUM
10. 10. 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
11. 11.  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.
12. 12. 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
13. 13. 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.
14. 14. 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.
15. 15.  If Holographic Projection is implemented successfully many touch screen such as one we seen in “Iron Man” movie can be implemented.
16. 16. HI-TECH FUTURE DREAM HAPPY FUTURE AWAITS FOR US.
