點讀筆的工作原理
有聲圖書上所有的內容,都采用了識別碼和反射紅外光的特殊涂料。印刷識別碼其實就是微型的二維碼類的東西,將圖書的字放大十幾倍就可以發現,里面含有豐富的數字信息。每一只點讀筆品牌產品的(de)(de)(de)筆頭,里面都有一個光電識別器(qi)(qi)(OID),它可以感應到圖(tu)片上的(de)(de)(de)數字信息(xi),用筆頭觸碰圖(tu)書,光電識別器(qi)(qi)就會開始掃(sao)描(miao)筆頭接觸部分的(de)(de)(de)書本上二維(wei)碼信息(xi),經(jing)過掃(sao)描(miao)后(hou)和電子原件的(de)(de)(de)傳遞(di),讀(du)取其中(zhong)的(de)(de)(de)二維(wei)碼信息(xi),傳遞(di)到點讀(du)筆內(nei)交由CPU進行處理,處理的(de)(de)(de)過程(cheng),是(shi)CPU的(de)(de)(de)識別過程(cheng),如果CUP識別成功,則會從點讀(du)筆的(de)(de)(de)存儲器(qi)(qi)中(zhong)將事先(xian)存儲好的(de)(de)(de)對應聲(sheng)音文件挑出,然后(hou)通(tong)過喇叭放出聲(sheng)音。
點讀筆有哪些功能
點(dian)(dian)讀(du)(du)筆(bi)擁有點(dian)(dian)讀(du)(du)、同(tong)步翻(fan)譯、復讀(du)(du)、跟讀(du)(du)、錄音、娛樂等(deng)多種功能,使閱讀(du)(du)和學習更(geng)有趣(qu),可充分實現(xian)寓教于樂的(de)(de)教育思想。孩子(zi)可以通過(guo)點(dian)(dian)讀(du)(du)筆(bi)參(can)與各(ge)種針對性的(de)(de)游戲(xi)和活動,不斷刺激觸(chu)覺、視覺、聽(ting)覺等(deng)感(gan)官來豐(feng)富他們(men)的(de)(de)體驗,增長他們(men)的(de)(de)興趣(qu),開發他們(men)的(de)(de)腦神(shen)經。
點讀筆怎么使用
先把點(dian)(dian)讀(du)筆(bi)(bi)的(de)電(dian)池(chi)按(an)進點(dian)(dian)讀(du)筆(bi)(bi)里,安裝(zhuang)電(dian)池(chi)后(hou),確定點(dian)(dian)讀(du)筆(bi)(bi)里有(you)安裝(zhuang)下載圖書文件(jian)。確定之后(hou),將點(dian)(dian)讀(du)筆(bi)(bi)的(de)開關打開。然后(hou)長按(an)開關鍵3秒左右(you),這樣(yang)就(jiu)完成了(le)開機(ji)。最后(hou)點(dian)(dian)圖書內(nei)要學習的(de)文字或圖片,就(jiu)能聽到相應的(de)語音。
點讀筆和點讀機的區別
點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)筆主(zhu)要適用于學齡前兒(er)童,0-6歲(sui)的(de)(de)幼(you)兒(er)都(dou)可以使用,而點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)機(ji)(ji)(ji)(ji)主(zhu)要定位(wei)于小學生為主(zhu)的(de)(de)群體。點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)筆是通過筆前端的(de)(de)攝像頭(tou)捕捉到印在點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)書上(shang)(shang)(shang)的(de)(de)暗碼(ma)信息(xi)后播放出(chu)相(xiang)(xiang)對應的(de)(de)聲(sheng)音,點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)機(ji)(ji)(ji)(ji)是通過感應筆點(dian)(dian)(dian)(dian)到機(ji)(ji)(ji)(ji)器(qi)(qi)板(ban)子上(shang)(shang)(shang)的(de)(de)位(wei)置,然后播放出(chu)相(xiang)(xiang)應的(de)(de)聲(sheng)音。點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)機(ji)(ji)(ji)(ji)產(chan)品因為要將(jiang)教(jiao)材(cai)放在機(ji)(ji)(ji)(ji)器(qi)(qi)上(shang)(shang)(shang),所(suo)以最小的(de)(de)點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)機(ji)(ji)(ji)(ji)都(dou)比(bi)一(yi)般的(de)(de)教(jiao)材(cai)要大,同時為了顯示(shi)一(yi)些內容,點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)機(ji)(ji)(ji)(ji)還設有顯示(shi)屏幕(mu)。而點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)筆相(xiang)(xiang)對于點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)機(ji)(ji)(ji)(ji)來說,就要小巧的(de)(de)多了,雖然在形(xing)狀上(shang)(shang)(shang)點(dian)(dian)(dian)(dian)讀(du)(du)(du)(du)筆有卡通造型、有筆的(de)(de)造型,但在大小上(shang)(shang)(shang),確實都(dou)盡量微小化的(de)(de),這樣也方(fang)便學齡兒(er)童手握學習。
