Eliza 的名字源于爱尔兰剧作家萧伯纳的戏剧作品《卖花女》中的角色，剧中出身贫寒的卖花女 Eliza 通过学习与上流社会沟通的方式，变成大使馆舞会上人人艳羡的 “匈牙利王家公主”。作为世界上第一个聊天机器人，Eliza 被其作者赋予了充满戏剧性的内涵。
尽管在当时已经存在一些基本的数字语言生成器（可以输出一些连贯文本的程序），但 Eliza 是第一个明确设计用于与人互动的程序。用户可以使用打字机输入人类的自然语言，获得来自机器的响应。正如维森鲍姆解释的那样，Eliza 使 “人与计算机之间的对话成为可能 ”。
Eliza 是维森鲍姆用一种名为 MAD-SLIP 的编程语言，在 36 位的 IBM 7094（一种早期的晶体管大型计算机）上开发的。在那个年代里，计算机时间是非常宝贵的资源，所以 Eliza 只能通过分时系统运行，用户只能通过电动打字机和打印机与程序进行远程交互。当用户键入一个句子并按 Enter 键时，一条消息会被发送到远端的大型机。Eliza 扫描消息中是否存在关键字，并将这些关键字组成新的句子，用以回复响应，打印出来并供用户阅读。
为了鼓励用户与 Eliza 对话，维森鲍姆使用 “狡猾策略”为 Eliza 设计了一种模拟罗杰式心理医生（一种以人为本的心理咨询）的对话风格。该程序将接受用户所说的内容，并将以一个问题作为回应，如下面的示例所示。（可以注意该程序如何接收 “男朋友”和 “沮丧”之类的关键字并重新使用它们。）
人：男人都是一样的。
Eliza：怎么说？
人：他们总是在困扰我们一些事情。
Eliza：您可以举一个具体示例吗？
人：好吧，我的男朋友让我来了这里。
Eliza：您的男朋友让您来了这里？
人：他说我很多时候都很沮丧。
Eliza：很抱歉听到您感到沮丧。
人：是的，我不开心。
Eliza 的这种对话方式，给人的印象就是计算机可以理解用户所讲的内容，而不必为对话提供任何新的补充。事实上，维森鲍姆仅用 200 行代码就实现了这一过程，使 Eliza 能够让人产生被机器聆听、理解的错觉。
为了测试 Eliza 与对话者互动的能力，维森鲍姆邀请学生和同事进入他的办公室，并让他们在他的观察下与机器聊天。他有些担忧地注意到，在与 Eliza 进行短暂互动期间，许多测试者竟开始对该程序产生情感上的依恋。他们会向机器敞开心，坦承他们在生活和人际关系中面临的问题。
更令人惊讶的是，甚至在维森鲍姆向他们介绍了 Eliza 的工作原理，并解释说它并不是真正理解了用户所说的任何内容之后，测试者对 Eliza 的这种亲密感仍然存在。尤其是魏森鲍姆的助手，尽管她一直看着该程序从零开始构建的全过程，但在测试时，这位助手仍然坚持要魏森鲍姆离开房间，以便她可以与 Eliza 私下交谈。
