使用影像眼震圖構建主動數碼動暈症檢測器

Abstract

本論文建構了一個基於前庭功能檢查之下眼球顫動偵測器。一般來說，身處虛擬場景會產生兩種情況。1.視覺和前庭系統之間的不匹配。隨之而來的不適會導致眼球震顫。2.跟踪視圖中的項目時眼睛快速移動。眼球運動模式看起來像眼球震顫。換句話說，這種類似眼球震顫的模式會導致不適。從這兩種情景來看，數碼動暈症與眼球顫動息息相關。然而，過往的研究的專注在虛擬環境而已，並沒有真實放在頭戴式顯示器(HMD)中及時偵測與探討。 本論文旨在基於前庭功能檢查之下，帶著頭戴式顯示器的情況，實作並記錄生理性溫差眼球顫動實驗、視運動眼球顫動實驗產生出來的數據，這兩個實驗分別與上述兩種情況一一對應，接著以上面兩種模擬下產生的眼球顫動規則，實作出一個眼球顫動偵測器。 在藉由這個眼球顫動偵測器，真實的抓取使用者帶著頭戴式顯示器使用VR時的眼球移動情況，探討VR環境下眼球顫動與暈眩的實際關係。

This paper constructs a nystagmus detector based on vestibular function test. In general, there are two situations in a virtual environment. 1. The mismatch between vision and vestibular systems. The accompanying discomfort can cause nystagmus. 2. Fast movement of eyes when tracking items in the view. Patterns of eye movement look like nystagmus. In other words, this nystagmus-like pattern causes sickness. From these two scenarios, cybersickness is closely related to eye movements. However, the previous researches focused on the virtual environment and did not detect and explore it in the head-mounted display (HMD). The purpose of this thesis is to calculate and record the data generated by the caloric vestibular experiment and the optokinetic nystagmus experiment based on the vestibular function test, with the head-mounted display. These two experiments correspond to the above two cases one by one, and then a nystagmus detector is made by the rules of eye movements pattern generated by the above two simulations. With this nystagmus detector, the actual user's eye movement with the head-mounted display using VR explores the real relationship between nystagmus and dizziness in VR.
