Presentation Transcript

  1. Using mobile telephones：cognitive workload and attention resource allocation Professor：Mr. liuyc Student：董瑩蟬

  2. 動機與目的 • 動機： 探討行動電話的使用對於safe driving 的cognitive workload and attention resource allocation • 目的： 探討不同的cognitive and mental workload levels effect on attention resource allocation，另外探討mobile telephones between hands-free and handheld方式

  3. 文獻整理

  4. 研究方法 1.According to the taxonomy of complexity by Fastenmeier (1995) and van Benda et al. (1983) 2.Four group traffic situation (1)Hh (2)Hl (3)Lh (4)Ll

  5. 研究方法 (一)、equipments 1.Volvo 850S(內有video cameras、laptop computer) 2.Nokia6150(with a CARK91免持聽筒) 3.TEMEC(VITA-PORT II)量測GSR and HRV 4.PDT(Recorded PDT correct hit rate and RT in ms)

  6. 研究方法 (二)、participants 1.40人(32M、8F) 2.條件：職業性的、駕車三年以上、每 年至少行使15000KM 3.Age：21~60 4.Mean age 39.6、mean annual 43100km

  7. 研究方法 (三)、變相(within) 1.自變項 The mobile phone task (HF and HH ) Conversation task (simple and complex) 2.依變項 PDT RT Mean speed

  8. 研究方法 (四)、分析方法 PDT及speed是用成對T檢定及回歸分析 (五)、實驗步驟 1.訓練7 KM 2.Speed of 110km/h、total driving time 1hr、 total distance 74km

  16. 討論 1.PDT measure of cognitive workload as also found in Martens and Van Winsum(2002) 2.Cognitive capture or cognitive tunneling would also appear to arise as a result of increased or high workload , similar noted by Martens and Van Winsum(2002)

  17. 結論 1.駕駛者在高負荷的情況下，大腦的資訊處理與反應皆和在低負荷的情況下不同。 2.手機的形式對於績效並無明顯的影響。 3.簡單的對話即會造成駕駛者分心，越複雜的對話，造成駕駛者能力和注意力的負面影響也越大。
