虛擬環境藉由網路，使其內含豐富的資源，能做為社交、模擬教學、學習所需。而屬其中一環的Second Life，為現今新興的數位學習平台，可做為線上學習環境，但由於操作較為複雜，對於肢體障礙者來說，即使提供相關電腦輔具，可能仍存在著使用上的困難。因此本研究透過9位一般使用者操作常見電腦輔具的模擬實驗，與3位擁有適當輔具之肢體障礙的典型個案之操作評估，以探討SL操作之可及性。研究結果顯示9位一般使用者可透過常見輔具來進行SL的使用，而3位典型個案也能在具適當輔具之下進行SL的任務。

The Internet has equipped virtual environments with a wealth of resources to meet social, simulated teaching, and learning needs, of which "Second Life" is one part. It is today's emerging digital learning platform used as an online learning environment. However, due to its relative operational complexity, people with physical disabilities might have difficulties using it even with the help of computer aids. Hence, through simulation experiments with nine general users with common computer aids, and operation-based assessment of three typical physical disability cases given appropriate computer aids, the feasibility of SL operation was explored. The results show that the nine general users engaged in SL use through the common aids, while the three typical disabled cases managed to engage in SL tasks as well through the use of appropriate aids.
