本研究的結果得知,此系統雛型較一般空間中的互動介面要來的自然。本研究所採 用的互動模式為『無意識 + 無動作』方式,也就是當受測者感覺勞累時,系統會 主動的察覺並改變環境來適應他,在實驗中我們也發現:

(1) 當受測者在環境不良時系統會自動的察覺到環境對使用者所產生的影響 (例如:心情低落、精神狀況不佳、發呆…等),並且給予環境燈光的刺激,

藉由系統判斷使用者Alpha波強度及a值持續的時間,系統會慢慢改變環境的 氛圍來回應使用者。

(2) 而當使用者真的很疲倦的狀況時,系統也會自動的察覺到使用者Alpha波的 強度以及持續的時間,並自動切掉燈光,讓使用者好好休息,另一方面也可 達到空間的節能效果。

5.1 研究貢獻

此研究成果也為智慧型空間開拓了新的視野,它讓我們能夠以更自然方式和空間環 境做互動,且讓人類與空間跳脫學習操縱介面的階段,直接與環境溝通。此研究貢 獻讓空間感知系統不再需要透過手勢、手套、語音等不直覺的控制,他讓生活更具 其便利性。若能將此系統裝置結合在更多的家具上,如將其整合在按摩椅上,藉由 使用者的腦波去控制按摩的部位,再將通訊裝置整合在椅子上,讓使用者再休息的 同時也可與另一個空間中的人溝同,此種方式即可改善以往找尋遙控器及如何使用 繁雜的介面的困擾。另外在醫療上,透過此種控制介面的裝置,更可讓肢體殘障、

無自主能力的患者,藉由系統主動去控制一些家電。且我們也可藉由腦波的訊號來 做設計思考的研究,探討設計者在做設計過程中腦波的變化,是否不同設計者在做 相同設計的過程中有過類似的腦波訊號。也可讓不同的人去感受相同的空間,並分 析其腦波的變化是否與設計者在設計此空間時有過類似的想法。

在此研究中我們發現透過此腦訊號控制介面系統,我們可以更了解人與空間的 互動關係不僅止於主動的控制,若能將此種較自然且非主動的互動模式結合在空間 環境中,讓空間更具智慧也更能夠與人達到和諧共存的目的。

5.2 研究限制與未來研究

在研究限制上,就目前醫學上的研究指出腦波並不能完全的被判讀,因為腦波具有 個人化的特質,且其不同時間不同環境因素影響下所測得的腦波都不盡相同,因此 在實驗中,我們所取得的參考標準為大多數人腦波的均值,所以在實驗中需要較長 的時間來判定使用者目前的狀態。

而儀器的準確性也是其限制之一,實驗中我們也常常因為貼片沒貼牢(受測者頭 髮過多、過長導致電極阻抗增加) 或使用者輕微的肢體動作,而導致到所測得的腦 波的雜訊比過高而未能取得需要的訊號。所以在本研究中,我們就容易測得的Alpha 波訊號的強弱來做互動的判斷,也因此我們只能用幾種易判斷的狀態來做互動,若 需瞭解人生理上、心理上得狀態則需更多的電極點分佈才可分析得出來,而其電極 的位置也是取得腦波訊號的關鍵,且越多頻道所得的訊號會越準確,因此在設置 上、腦波的分析上也就更加的繁瑣、複雜。因此就目前的技術我們並不能同時控制 多樣的裝置,所以此裝置的功能性較弱,這也是其研究的限制之一。

後續發展可就腦波做更深入的研究,也就是將判讀出來不同狀態的個人化腦波 訊號直接操縱空間中的多樣化的裝置,未來科技的進步,腦波偵測的儀器與訊號分 析的方法一定會有更進一步的發展,未來的智慧型空間將能直接與人類的思考互 動,而人類的生活不需有任何的改變,空間即可以回應人的需求,更貼近人的想法,

這才是真正的智慧空間。
