• Background

• Purpose

• Issue

• Solution

Introduction•Need to check selected the device and ready or not.•Tend to turn to device a remote controller when operate it.

(1) Construct a database for record each coordinates of device (2) Use electric compass and gyro sensor what are into iPhone both.

•Automatically perceive a device what is want to operate it

(1) How to perceive the device what is user want to operate one.(2) How to switch the device for operation.

System 2iPhone Application algorithm during searching

IF M > 1 foreach(all exists devices RSSI){

IF RSSI0 < RSSIi THEN RSSI0 = RSSIi

} connect to device RSSIi’s. ELSE IF M = 1 connect to device0

ELSE IF M < 1 non-action

M : デバイスの数devicei : デバイスRSSIi : デバイスの電波強度RSSI0: 最近RSSI


System 3iPhone Application algorithm during data synching

IF Appliances data == NULL get data from device store to db into smartphoneELSE IF Appliances data == Require UPDATE get data from device update dbELSE non-action
