A brainwave emotion detecting device with displaying color is provided in the present disclosure. The brainwave emotion detecting device includes a brainwave detecting module, a processing module, a display module and a storage module. The brainwave module is configured for detecting a plurality of brainwave parameter of a user. The display module is used for display a plurality of colors corresponding to a plurality of emotions of the user. The storage module is used for storing a plurality of emotion models and a plurality of emotion reference values. The processing module is electrically connected to the brainwave detecting module, the display module and the storage module. The processing module determines the emotion of the user according to the brainwave parameters. The processing module compares the brainwave parameters and the emotion models to determine the emotion of the user. An emotion strength is determined according to the comparing result of the brainwave parameter and the emotion reference value. The processing module controls the display module to display a color and a luminance corresponding to the user’s emotion and the emotion strength.本發明實施例提供一種利用色彩顯示的腦波偵測情緒裝置,其包括:一腦波偵測模組、一顯示模組、一儲存模組以及一處理模組。腦波偵測模組,偵測一使用者的複數個腦波參數。顯示模組,用以顯示多種色彩以對應於多種情緒。儲存模組,用以儲存對應於一使用者的複數個情緒模式與複數個情緒基準值。處理模組,電性連接於所述腦波偵測模組、所述顯示模組以及所述儲存模組,根據該所述腦波參數判斷一使用者情緒。其中,該處理模組比對所述腦波參數與所述情緒模式決定所述使用者情緒的類別,比對所述腦波參數與所述情緒基準值決定所述使用者情緒的強度,並且根據所決定的所述使用者情緒的類別與強度,控制所述顯示模組來顯示對應的色彩種類與色彩強度。1‧‧‧腦波偵測情緒裝置2‧‧‧遠端伺服器11‧‧‧腦波偵測模組12‧‧‧處理模組13‧‧‧顯示模組14‧‧‧儲存模組15‧‧‧通訊模組16‧‧‧可充電池17‧‧‧警示模組
