The present invention relates to an electronic guide device for guiding blinds. The electronic device includes a receiving unit, a calculating unit, a judgment unit, and a warning unit. The receiving unit includes a laser projector for projecting objectors at front of the electronic guide device, and a camera module for receiving a signal reflected by the objectors at front of the electronic guide device. The calculating unit is configured for calculating the distance between the objectors and the electronic guide device, basing on the reflected signal. The judgment unit is configured for judging whether the distance between the objectors and the electronic guide device is within a predetermined range. If the distance between the objectors and the electronic guide device is within the predetermined range, the warning unit sends out a warning signal to the blinds.一種電子導盲裝置,其用於識別盲人前方物體並發出訊號,電子導盲裝置包括一接收單元、一計算單元、一判斷單元及一提示單元。接收單元包括一雷射投影器及一攝像頭,雷射投影器用於照射前方物體,攝像頭用於接收前方物體反射回來的訊號。計算單元根據攝像頭接收的前方物體反射回來的訊號計算得到盲人與前方物體之間的距離。判斷單元判斷計算單元計算得到的盲人與前方物體之間的距離是否在一預定的範圍內。若判斷單元判斷出盲人距離前方物體在預定的範圍內,則提示單元發出用於提醒盲人的提示訊號。100‧‧‧電子導盲裝置110‧‧‧接收單元111‧‧‧雷射投影器112‧‧‧攝像頭120‧‧‧計算單元130‧‧‧判斷單元140‧‧‧提示單元150‧‧‧輸入單元160‧‧‧存儲單元170‧‧‧比較單元180‧‧‧命令輸出單元
