展示HN：无屏幕儿童短信服务
我想分享一个我正在进行的项目，这个项目让我的女儿可以在没有手机或屏幕的情况下给我发短信。她手写一张便条，然后通过光学字符识别（OCR）将其转换并以短信的形式发送给我（同时附上便条的照片，因为五岁小孩的字迹可能有些难辨）。我回复后，她的回复会通过热敏打印机打印出来。这项活动出乎意料地有趣。
我添加了一些功能：
- 多人短信：我设置为默认接收者，但她可以写“to: dada”或“to: <手机号码>”，系统会将消息发送给指定的接收者。我为编辑手机号码/设备ID与名称的映射制作了一个简单的用户界面。
- 额外打印纸：打印时会额外打印一张纸，上面写有“to: <发件人>”，方便她进行双向聊天。
- GPT支持：她可以写“to: GPT”，系统会调用GPT API并打印出回复。我让GPT的回复易于小学生阅读，以便她自己能看懂。
- 针对我的GPT支持：我可以发送“to: GPT”，系统会回复我，而不是打印消息。这对我那个对太空充满热情的三岁小孩来说非常棒。
- 设备间短信：我还设置了另一台设备，它们可以互相发送短信。
- 朗读功能：有一个按钮可以朗读扫描仪下的文本。这对我那个还不会阅读的三岁小孩很有帮助。
总体来说，GPT表现得非常出色。它在识别儿童字迹方面比Tesseract或Google OCR要好得多，而且能够以适合她年龄（和阅读水平）的方式回答问题，真是太好了。

I wanted to share a project I’ve been working on that allows my daughter to text message me without a phone or screen. She handwrites me a note and then it OCRs and sends it to me as an SMS (along with a picture of the note because 5 year old handwriting can be tricky). I text back and my response is printed for her via a thermal printer. It’s been surprisingly fun.<p>Some features I've added:<p>- texting multiple people - I'm the default but she can write "to: dada" or "to: <i>phonenumber</i>" and it'll text the recipient. I made a simple UI for editing the phone number/device id to name mapping.<p>- A bit of extra paper is printed with "to: <i>sender</i>" at the top to make it easy to chat back and forth.<p>- GPT support - she can write "to: GPT" and it'll call GPT API and then print out the response. I prompted GPT to make it easy to read for an elementary school child so she can read it herself.<p>- GPT support for me - I can text to: GPT and it'll text me back rather than printing a message. This has been great for my space-obsessed 3 year old.<p>- texting other devices - I have another device set up and they can text message each other.<p>- read outloud - there's a second button that reads whatever text is under the scanner. This is helpful for my 3 year old who can't read.<p>GPT has been fantastic all around. It's way better at OCR-ing kid handwriting than Tesseract or Google OCR and being able to ask questions and get answers at an age (and reading) appropriate level has been great.<p><a href="https://imgur.com/6qm6JmK" rel="nofollow">https://imgur.com/6qm6JmK</a><p><a href="https://imgur.com/xRPkRwu" rel="nofollow">https://imgur.com/xRPkRwu</a><p><a href="https://imgur.com/EZEHBEK" rel="nofollow">https://imgur.com/EZEHBEK</a>
