This document discusses several next generation user interfaces including gesture interfaces, augmented reality, voice user interfaces, and tangible user interfaces. Gesture interfaces allow interaction through bodily motions detected by cameras or sensors. Augmented reality enhances the real world with computer-generated perceptual information. Voice user interfaces enable interaction through speech. Tangible user interfaces couple physical objects with digital information for manipulation. These emerging interfaces provide more natural, intuitive ways for humans to interact with technology beyond the traditional graphical user interface.

Next generation User interfaces
- 1. 1 NEXT GENERATION USER INTERFACES HARSHAD K T S5 MCA Roll NO: DOALMCA013 NIELIT CALICUT
- 2. Contents Introduction Technologies Gesture Interfaces Augmented Reality (AR) Voice User Interface (VUI) Tangible User Interface (TUI) Conclusion References
- 3. INTRODUCTION User Interface Graphical User Interface (GUI) User interfaces provide a means of Input, allowing the users to manipulate a system Output, allowing the system to indicate the effects of the users' manipulation
- 4. Here are some key features of 1. Gesture Interfaces 2. Augmented Reality (AR) 3. Voice User Interface (VUI) 4. Tangible User Interface (TUI)
- 5. Gesture Interfaces Gesture recognition is a topic in computer science interpreting human gestures via mathematical algorithms. Gestures can originate from any bodily motion (commonly originate from the face or hand ) It enables humans to communicate with the machine Gestures enabled applications provide interface to interact with the system
- 6. Gesture types Offline gestures : Those gestures that are processed after the user interaction with the object. An example is the gesture to activate a menu. Online gestures : Direct manipulation gestures. They are used to scale or rotate a tangible object.
- 7. Uses of gestures interfaces 1. Sign language recognition 2. Control through facial gestures 3. Alternative computer interfaces 4. Immersive game technology 5. Affective computing 6. Remote control
- 8. Input devices 1. Wired gloves Data glove 2. Depth-aware cameras 3. Controller-based gestures 4. Single camera Depth aware camera
- 9. Sixth Sense Technology (Example system ) 'Sixth Sense' is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information Pranav mistry , inventor of the SixthSense
- 10. prototype is comprised of a Pocket Projector, a Mirror and a Camera connected with the mobile computing device in the users pocket. The software program processes the video stream data captured by the camera and tracks the locations of the colored markers Sixth Sense also supports multi-touch and multi-user interaction
- 11. Applications Navigate a map Multi-touch based systems Zoom in, zoom out Drawing application Takes photos using framing gestures It augments the physical objects
- 12. Devices used Navigation, Zoom in / zoom out Taking photos with gestures Augmented reality using 6th sense technology
- 13. Augmented Reality (AR) Augmented reality (AR) is a live, copy view of real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data
- 14. AR enabled camera Gaming Application Navigation Live AU
- 15. Devices Used Hardware Display Head-mounted Display HMD Eyeglasses Contact lenses EyeTap Handheld Spatial Augmented reality Contact lenses Input devices EyeTap
- 16. Applications Architecture Google Glass view Commerce Education Gaming Medical Military Education Navigation Navigation Commerc e
- 17. Voice User Interface (VUI) A voiceuser interface (VUI) makes human interaction with computers possible through a voice/speech platform in order to initiate an automated service or process.
- 18. Future Uses 1. Smart phone and PDA`s working 2. Helps the people who are slow in typing, (avoids straining and Injuries ) 3. Helps the handicapped people 4. Facilitate to create portable devices (with no keyboard, no separation between content and keyboard on the touch screen ) 5. Reduce the devices half in size ( laptop computers , desktop, sliding mobile devices)
- 19. 1. The VUI must be sophisticated enough to distinguish between the input commands, and background conversation 2. It need highly sophisticated software in order to accurately process and find or retrieve as per the particular user's preferences
- 20. Example gadget : Google glass Samsung S-voice
- 21. Understanding Speech Technology Barge-In Grammar Tuning Voice User Interface VXML The Voice XML Specification The Voice XML Advantage
- 22. Tangible User Interface A tangible user interface (TUI) is a user interface in which a person interacts with digital information through the physical environment.
- 23. Characteristics TUI Physical representations are computationally coupled to underlying digital information. Physical representations with visible/ tangible interfaces for interactive control. Aware of physical objects through sensors and coupled to digital representation
- 24. Properties of tangible user interfaces space-multiplex both input and output concurrent access spatially aware (position, area, size etc)
- 25. Object recognition in TUI
- 26. Surface computing Surface computing enables user to interact directly with the system Without using keyboard and mouse Features Direct interaction Multi user experience Multi touch Object recognition
- 27. Application Used in hotel, restaurants and retails stores In casinos (watch video , games, navigation, ..etc) Digital image painting Advantages Disadvantages Wireless communication Not portable Time saving Very Expansive New and improved learning experience
- 28. Surface commuting systems Microsoft pixelsense
- 29. CONCLUSION Next Generation user interfaces are focused on real world objects The future electronic gadgets will be working on the above discussed concepts Many of these technologies are implemented now and some of them are in developing stage The trend changes in Electronics and IT will make effect on future user interfaces also
