實作可設定式之行動感測平台 / Design and Implementation of a Configurable Service Platform for Mobile Sensing

黃建烽, Huang, Chien Feng Unknown Date (has links)
長久以來,學者專家為進行各種與人們行為有關的實驗,使用了多種方法進行數據的收集,卻存在著一些缺點或是成本過高,不易大規模推行。近年來,隨著行動科技的高速發展,智慧型手機已經相當普及。由於智慧型手機內建眾多的感測器(Sensors)及裝置(Devices),透過撰寫及執行特定的手機應用程式(APP),即可蒐集手機所偵測到的使用者行為相關之資訊,並加以分析處理。行動感測(Mobile Sensing)遂成為新型態的數據收集方式。但是,僅就特定之感測實驗所需數據項目,開發數據蒐集的行動應用程式,亦或是不管實驗需求,讓程式蒐集全部項目的感測數據,都不是理想的作法:不是欠缺彈性考量就是未能考慮手機使用者的隱私關切。 本研究實作一個通用於所有行動作業系統上之可設定式之行動感測服務平台,它可以協助研究者根據其需求自行設定感測實驗項目及其條件規範。之後,透過建立於伺服器端與客戶端之間特定的資料交換機制,進行實驗的發布及兩端的互動溝通。整體運作過程中,客戶端的參與者只需簡易地安裝一套行動應用程式,便能夠輕鬆參與進行各種感測實驗、貢獻實驗數據。最後,我們模擬幾項實驗,用以驗證平台之實際運作效能。 / Experimental data obtained in scientific research is extremely important. For a long time, people use a variety of methods for data collection, but most of them are either restricted or expensive. In recent years, with the rapid development of mobile technology, smart phones are becoming very popular. With many built-in sensors and devices, smart phones can be used as a new tool of data collection, hence the emergence of mobile sensing. By installing a mobile application (APP) on a user’s smart phone, researchers can collect those required sensor data from the user and analyze it for their study. This research presents a configurable service platform for mobile sensing which aims to reconcile the flexibility needed by researchers and privacy concerns of smart phone users. In particular, our platform allows researchers to use our GUI tool to easily set up an experiment by composing an experiment configuration file (ECF) which specifies the sensor types to collect and the filtering rules for data selection. Users of smart phones can join any experiments by installing a single piece of logger APP developed according to our ECF specification. Besides, users will be fully informed of the data to collect before agreeing to participate a specific experiment. In such a manner, we achieve a proper balance between flexibility and privacy. Finally, we conducted several experiments to validate the feasibility of our service platform with users of Android smart phones.

安卓智慧型手機上可設定式之行為感測記錄器 / A Configurable Activity Logger for Android Smartphones

王俊翔, Wang ,Chun Hsiang Unknown Date (has links)
近年來隨著智慧型手機的興起,人們開始利用智慧型手機處理日常生活事務及社群娛樂。無形中,已逐漸的改變日常行為模式。因此,許多學者也開始進行人們使用智慧型手機狀況的研究。 若透過傳統問卷等方式蒐集分析使用記錄,受訪者可能因訪問員的外在因素而影響問卷有效性。為解決此問題,很多研究開始在智慧型手機中安裝應用程式,蒐集使用記錄,藉以分析使用行為。然現今此類應用程式,都是為特定的研究進行開發,缺乏了彈性的考量。因此,本論文設計一個是用於安卓智慧型手機的可客製化行為感測記錄器,提供研究學者依各自需需求產生實驗項目規格檔,由受測者下載至手機,透過我們的行為感測記錄器,記錄平時手機操作行為之相關記錄,並於指定之時機下將記錄上傳供研究學者統計分析,以符合個別實驗之要求。 本研究重點在於如何定義彈性且多樣化的實驗設定檔,並考量載記錄感測過程中,電力大量消耗和受測者隱私資保護的議題,提出因應的解決方法。我們設計與執行幾個實驗來驗證此行為感測記錄器,初步看來,此記錄器可以滿足我們的主要需求,但結果也導引出一些需改進的設計議題。 / In recent years, with the rise of smart phones, the public began to take advantage of smart phones in daily life and social engagements. Virtually, smart phones have gradually changed people's behavior patterns so that researchers are eager to understand the how people use smartphones in their daily life. In this thesis, we present a configurable activity logger for Android smartphones for recording a smartphone’s sensor data and the user’s operations. Instead of one Android App for each researcher’s experiment, our approach is to devise a general logger App that can be customized to collect different data items according to the needs of various researchers. Specifically, our logger App accepts experiment configuration files in which researchers specify what data items to collect and at what frequency, and then conduct the logging task accordingly for each experiment. In other words, our logger works like an interpreter on such experiment configure files. Besides customizability of logging items, our logger concerns the saving of electricity and the preservation of user privacy. Firstly, we have applied various power saving tips published in the literature to the design of our logger. Secondly, we have refrained from collecting any contents that may reveal the user’s identify or that may invade user’s privacy. To evaluate our logger, we have designed and implemented a few data collection experiments. The preliminary results show that our logger can fulfill most of the requirements we set up, though thy also reveal some improvements we need to work on in the future.
