中文摘要 | 本實驗以受測者的操作表現做為不同視訊方式影響空間定位動作難易的指標。首 先探討立體視覺的因素及評判方法和提出可行方法,並以實驗室模擬法進行計測。 攝影機角度及視覺型態互為實驗自變項,進行連續定位動作,計測其操作時間、 偏好友立體強度感覺之比較。實驗一計測各種間接視覺對模擬遠端操作效率的影 響。將立體視覺線索利用反射式立體鏡所造成之立體視覺,及近於互相垂直約兩 架攝影機所提供的雙畫面之方法,計算這兩種方法對操作效率影響之差異,結果 顯示利用反射式立體鏡之立體視覺有較佳之表現。實驗二計測在視線固定的情形 下,不同的攝影角度對受測者之影響,結果顯示以不同於受測者的視線角度(45 度代替15度),其執行效果無顯著差異。實驗三驗證在無參考線索之下,攝影機 與操作平面呈45度的視覺加上90度的參考視覺,其表現及學習效果不如立體視 覺之操作績效。實驗四顯示,立體對組的視覺操作受疲勞因素的影響較大,而較 不受學習與經驗因素的影響;雙攝影機組的操作受學習與經驗因素的影響較大, 而較不受疲勞因素的影響。 |
英文摘要 | The extent of difficulty in different visual aspects affecting spatial positioning movement in this experiment, is indicated by the performance of the participants. We begin by exploring the stereoscopic vision factors and the process of decision making. Feasible solutions are formed and simulating experiments performed for statistical calculation. In this experiment, camera perspectives and forms of visions each enact as the reciprocate variable of the other. Consecutive focusing are performed and the total time consumed, individual preference and stereoscopic impacts are recorded accordingly. The first experiment evaluates the impact of indirect vision on Tele-operation. A stereoscopic vision created by reflective stereoscopic lenses, and a double vision produced by a pair of almost perpendicularly placed cameras, are compared to assess the efficiency of operation. The result showed that stereoscopic vision created by reflective stereoscopic lenses performed better. The second experiment examines how, under the condition of stationary vision, different camera angles affect participants. The result showed that in employing different visionary angles from the individuals being tested (45 degrees in lieu of 15 degrees), there were no significant discrepancies between the two. The third experiment involved positioning a camera at a 45-degree angle to the operating surface with a 90-degree referential vision. The result verified that with no referencing implications, both performance and learning effects came up less than that of the stereoscopic vision. The last experiment exhibited that the performance of the visionary group in stereoscope, is more affected by the extent of fatigue than learning or experience factors; on the other hand, the performance of the group that worked with a pair of cameras, is affected more with learning and experience factors than the extent of fatigue. |
