[摘要] 該文探究利用虛擬現(xiàn)實技術(shù)(Virtual reality,VR)作為恐高場景模擬手段的可行性。通過分析虛擬現(xiàn)實技術(shù)的發(fā)展及優(yōu)勢結(jié)合目前暴露治療手段,利用穿戴式VR設(shè)備及生命體征采集設(shè)備對人在體驗虛擬場景前及體驗中的心率、肌電、皮溫數(shù)值進(jìn)行采集,并進(jìn)行前后對比。結(jié)果顯示將從同一批體驗者身上采集到的兩組數(shù)據(jù)進(jìn)行配對檢驗差異有統(tǒng)計學(xué)意義(P<0.05)。從而得出結(jié)論利用虛擬現(xiàn)實模擬恐高場景是可行的。

[Abstract] This paper explores the feasibility of using virtual reality (VR) as a simulation method for height-altering scenarios. By analyzing the development and advantages of virtual reality technology combined with current exposure treatment methods, wearable VR devices and vital sign collection devices are used to collect human heart rate, myoelectricity, and skin temperature values before and after experiencing virtual scenes, and before and after were compared. The results showed that the difference between the two groups of data collected from the same batch of participants was statistically significant (P<0.05). Therefore, it is concluded that it is feasible to simulate the height-altering scene using virtual reality.

在臨床工作中心理治療作為一種常用且重要的治療手段已被證實具有切實的療效[1]。其中暴露治療作為心理治療的一種,它的形式主要包括實體暴露療法和想象暴露療法。實體暴露法是一種快速的行為療法,它鼓勵患者直面可能導(dǎo)致其恐懼和焦慮的場景,并持續(xù)到緊張感消失,此方法不但受地域的限制還具有一定的危險性;想象暴露法通過指導(dǎo)求治者想象恐懼情景來消除焦慮和不良反應(yīng),若沒有足夠的想象力此方法將受很大程度的限制。不難看出目前無論哪種治療手段在制造恐高場景上都顯得捉襟見肘。能制造出能激發(fā)人體應(yīng)激反應(yīng)的恐高場景是治療和評價的前提,隨著計算機(jī)等技術(shù)的發(fā)展利用虛擬現(xiàn)實制造恐高場景逐漸成為可能。
