dc.description.abstract目前,相關的室內定位研究以及實際的需求越來越大,而使用iBeacon來當定位工具的情形也越來越廣泛,但定位的精準度卻一直是亟待改善的部分。尤其是當對象為盲人時,因為他們無法像一般人一樣,能夠憑著看的見周遭環境來做自身位置的判斷,故定位的精準度對他們來說更是重要。 本研究主要是利用手機以及太和光所開發的有聲iBeacon來做室內定位,經由iBeacon本身所發出的聲音,利用回歸分析法來證明聲音DB值與RSSI訊號為正相關。並依此為基礎,設計手機上的導航APP,透過不同場域的實測,證明經由聲音的輔助確實能夠有效的提升定位精準度,修正因為RSSI訊號的不穩定所造成的定位誤差,比起以往其他的相關研究,單純只用RSSI訊號來做為唯一的定位依據,提供了一個全新的方法來做定位精準度的強化。最後,再實際的模擬盲人來操作,其結果的確有效的幫助並改善了盲人在室內移動的不便。zh_TW
dc.description.abstractCurrently, the needs for the studies and practical demand for indoor positioning have been growing gradually. Additionally, iBeacon for positioning has been widely used recently; however, its accuracy has always been an issue for improvement. Particularly when the users are people with visual impairment, because they are not able to judge their positions by seeing their surroundings as other ordinary people do; therefore, the positioning accuracy is extremely important for them. The purpose of this study is to utilize mobile phones and Audio iBeacon which developed by THLight Inc. for indoor positioning. Through the sound from the iBeacon to conduct a regression analysis method and prove the dB value has a positive correlation with the RSSI signal. Afterward, design a navigation mobile application with this basis and implement various real-world experiments to confirm the design could effectively increase the positioning accuracy from creating an auxiliary sound with the RSSI signal, as well as correcting the errors that caused by the unstable RSSI signal. Compared with other studies that purely considered RSSI signals for the only positioning basis, this study presents a brand new auxiliary system to reinforce the positioning accuracy. At the end of the research, this study also simulated real scenarios for the people with visual impairment to operate the design; the result indeed demonstrated that the design could assist the visually impaired users and improve their inconvenience in moving indoors.en_US
