There are many connected devices and piece of equipment designed to perform a specific task. The smart devices used in home are one of the indicative fields. User may confused while using remote controller device it contains multiple buttons in one remote, that equipment increase the difficulty of devices in home spaces. Showing unnecessary function interface and buttons on the screen of the remote controller that increase bandwidth utilization and not maintain user friendliness. Project aim is to develop remote control system that can be controlled home appliances using Infrared Signal (IR) and Bluetooth System in smart home. Remote control system detects devise automatically when user points the controller to it. Remote control system user interface (UI) shows only required fields, functions, and buttons on remote device of a target device that is necessary. Remote controller uses directionality features which enable control by pointing to the target device and shows only target device interface on remote controller screen.

Developing remote control system for home appliances in smart homes. Point target device and press the visible button on remote controller is directional technique. It searched devices and appliances in home space when user pointing to the controller. Controller shows user interface on the screen when it controls any device. Controller controls any device then it shows user interface on the mobile screen. The UI shows only functional buttons that are necessary for the current control context. The UI provides user-friendly interfaces and operations, which allow users to simply enable and control the target device.
Finite state machine is used to represent all operational states of a device and dependencies among these states.
Control operations shows by many bit-string formatted control codes that are used in proposed scheme to decrease the bandwidth consumption. In real prototype are implemented in smart homes to demonstrate the feasibility of the proposed scheme. The external control box is controlled a TV by directly pointing to the TV.
There are two state dependencies are included in the control process of the TV. First, Fan can only be started, by pressing the power button when it is powered off. Other buttons are useless. Second, when the TV mode is Powered-on. Volume button, channel button and menu button is displayed on screen of the remote controller device. This technique is useful to control and access the device to display control interface on the screen of remote controller.
Using remote device user can access many home appliances and devices in smart homes. Remote devices contained number of buttons and multiple transreceiver. This setup provides higher operational complexity around the space with numerous devices or appliances.
Using universal remote controller, integrate multiple functions of home devices or appliances into one single remote controller.
While using universal remote controller it leads many issues because we multiple function and buttons displayed on single remote controller, so it’s not user-friendly.
To detect any device in home appliances many techniques have been proposed that are used to develop remote controllers, typically that are liquid crystal display screen, networking capability, Universal plug and play. The Universal plug and play is very useful technique in universal remote controller.
Using this technique the home appliances or any device can be detected automatically. Transmission between two devices is done using IR infrared signal and Bluetooth. As per the home appliance or device the universal remote control shows the buttons on the remote or android phone. User interface is automatically generated from descriptions and properties of the device.
While using a universal plug and play technique, the screen of the controller shows many devices around space that are available, multiple devices of same type or appliances are frequently displayed on the screen of the controller e.g. tv, fan, light, lamp, Air conditioner. That tends to or cause user-friendliness. This shows, it is not user-friendly to users. A user-friendly and zero-configuration design is make used of in this service, both the Directionality of infrared and the state dependencies of the device operations have not been considered.
In addition, a neural machine interface system also called as mind-machine interface (MMI), direct neural interface (DNI), brain-machine interface (BMI), is a direct communication pathway between an enhance or wired brain and an external device. This system is used to achieve mental fatigue problem. The neural machine interfaces if too expensive for implementation in smart homes. The device operations and state dependencies are not monitored or considered as per the user perception, and error perception feedback.
In addition, the infrared directionality has been introduced in previous cases. This system requires a specific and modified controller. In addition, the usage of this system is limited to televisions. By using infrared directionality technique, this technique is only limited for televisions system.
Recently, For Controlling home appliances in smart homes the new approaches are developed. Including use of voice commands and figure gestures. In noisy environment voice control is not work properly. Gestures can originate from any bodily motion or state, but commonly originate from the hand and face. It is difficult to catch the operational behavior of this system before using this, users have knowledge of that technique that are probably not natural.
Home Automation or domotics is used for building automation for a home called as smart home or smart house. A home automation system will control lighting, climate, entertainment systems and appliances. It may also include home security such as access and alarm systems. When connected with the internet, home devices are an important constituent of the internet of thing.
A home automation system typically connects controlled devices to a central hub or “gateway”. The user interface for control of the system uses wall-mounted terminals, tablet or desktop computers, a mobile phone application, or a Web interface, that may also be accessible off-site through the Internet. This technology is used over the internet.
We have seen multiple problems regarding user interface in numerous fields. As per above features of the directionality of the infrared characteristic and the state dependencies of the device operations are not considered.
As per previous case, this control interface represent a hectic interface for electronic devices, in which predefined menu needs to be prepared and the UI need to be arranged prior to set up of the control system. While using controller, the controller user interface shows many unnecessary, non required function and multiple buttons at that time. So there is higher probability of incorrect operation is may be generated when accessing or controlling the appliances in smart home space. Hence, the unnecessary function and buttons that are not required at that time that is not displays that are introduced by state dependencies of the device operation.
For Example, when a TV is powered off, the only necessary button is power on button. Powered button is shown when TV is powered off. In the case, when TV is powered on then the necessary button will show by remote controller device that are volume button, channel button, powered off button.
This study is examined to be an evaluation over the less bandwidth-consumptive control system for home appliances or devices. Questions are always given innovative research ideas and clarity about research. Research questions play a vital role for identifying concepts, and issues in the survey. The questions related to our study are given below. Which is the best technique suitable for controlling the home appliances? Why most system prefer PPRC(Point and Press Control) and PPCB(Point and Press Control Box) ? What is the reason to usage different technique for controlling home appliances?
In this proposed research work to design and implement a system that can be evaluated the overall performance evaluation of Point and Press technique.
As per difficulty of numerous devices and appliances increases, multiple functions and unnecessary buttons also created or design for a particular remote controller in home spaces. That is not user-friendliness; user may be confused to perform a simple operation on a remote controller.
We are using different kind of home appliances which are the electronic device which can be controlled by different remote. So i have 10 kind of devices. I need to have 10 different remote for each device, and it is difficult to remember where I place it. So for that we use directionality features in the single remote controller device that can handled multiple devices in single remote approach.

Result and Discussion
The remote control scheme employs the hexadecimal string as the transmission message, the bandwidth consumption is always less than the previous two approaches. In addition, the accumulated bandwidth consumption of directionality features is also more stable and slow compared with the conventional two approaches. The final results indicate that the accumulated bandwidth consumption of the remote control system, the conventional XML, and the RF4CE-based approaches are 1.32, 40.674, and 34.38 Kbytes, respectively. Therefore, the reduced percentage of bandwidth consumption of remote control system compared with the conventional XML approach and the RF4CE-based approach is 96.75% and 96.16%, respectively.
The proposed remote control system not only enhances the features of user-friendliness but also establishes a less bandwidth-consumptive control system. Also reduce the difficulty of remote control systems using directionality features, controlling multiple smart home devices pointing directly to target device using single remote controller.
