A Low-Cost Hand Gesture Human-Computer Interaction Technology

New innovations


This paper shows a minimal effort hand motion human computer association framework for remote controlling of TV and Set-Top-Box (STB). The proposed framework adds just a little to the equipment cost as only a webcam is utilized, and can keep running on standard and even low-end TV and STB with no product and equipment updating.

Human-Computer Interaction



Presentation
Signal based human-PC association (HCI) gives more natural and subjectively agreeable correspondence among human and gadgets. Many hand signal HCI Technology in view of profundity pictures have been produced. These frameworks utilize costly multi-see stereo camera or extraordinarily planned imaging gadget to produce profundity pictures. In addition, these frameworks need to keep running on superior CPUs or GPUs because of complex calculation. 


Incorporating these hand signal HCI frameworks into general shopper gadgets, for example, TV and STB, adds extensively to the cost. This paper exhibits a minimal effort hand signal HCI framework for remote controlling of TV and STB. The proposed framework is practicable to incorporate into TV, STB and other shopper gadgets, profiting from its three favorable circumstances:



1) The proposed framework adds just a little to the equipment cost as only a USB webcam is utilized.
2) The proposed framework can keep running on standard and even low-end CPU utilized by TV and STB.
3) The control orders issued by proposed framework are changed over to standard mouse/console occasions by a virtual mouse/console driver, with the goal that it doesn't have to overhaul the current programming and equipment of TV and STB.

Strategies and Implementation
The proposed hand motion HCI framework has two states: sniff state and initiation state. Under sniff express, the framework examines the video arrangement and distinguishes if any client has communicated the expectation of controlling the TV or STB with a pre-characterized actuation hand motion. The framework does not issue any control charge under sniff state, so that motions in every day life don't incidentally control the TV or STB. 

Once the enactment hand signal has coordinated, the "hand" with the initiation motion will be followed and after that the framework changes to actuation state. Under enactment express, the framework tracks the client's hand, coordinates the fleeting directions of the followed hand to pre-characterized signal layouts, and composes the comparing control orders into the virtual mouse/console drivers to mimic the mouse, console, and remote controller. On the off chance that there is no pre-characterized motion distinguished for quite a while (say, 3 minutes), the framework changes back to sniff state.

Enactment state
Under enactment express, the client's face and hand are additionally followed utilizing a similar methodology utilized under sniff state. The hand directions of the present casing and the last edge are changed over to relative organizes by an arrange mapping module. The relative directions are then built into a virtual mouse driver to make the mouse cursor move with the client's hand. We find that the moving mouse cursor is a helpful criticism to the client and makes the proposed hand motion HCI framework more easy to understand. Moreover, mouse operation is an effective and basic route for getting to the various elements of present day TV and STB. 

The worldly directions of the followed hand are likewise dissected by a signal investigation module which cuts the directions into motion fragments as indicated by the fleeting soundness and matches the motion portions to the pre-characterized motion layouts. In the event that any predefined motion is matches, the relating control order is built into the virtual console drivers to reproduce the remote controller or console. Eight pre-characterized signals, i.e. left, appropriate, up, down, enter, zoom-in, and zoom-out, are predefined in the proposed framework. In the event that there is no pre-characterized signal identified for quite a while (say, 3 minutes), the framework changes back to sniff state.

CONCLUSION

A minimal effort hand signal HCI framework for remote controlling of TV and STB has been proposed in this paper. The proposed framework adds just a little to the equipment cost as only a webcam is utilized, and can keep running on standard and even low-end TV and STB with no product and equipment overhauling. In not so distant future, the proposed framework will be moved up to bolster multi point connection.
