What is the name of the user interface of the Apollo 11 computer?

The Apollo Guidance Computer (AGC) on board Apollo 11 had 2048 words of RAM, which could store "temporary results" – data that is lost when there is no power.
Each word comprised 16 binary digits (bits), making a total of 32,768 bits of RAM memory.
This amount of memory is insufficient to store a single article, let alone thousands of emails, songs, and photographs like modern mobile phones.

The latest phones typically have 4GB of RAM, which is approximately 1,048,576 times more memory than the Apollo computer had in RAM.
The iPhone also has up to 512GB of ROM memory, which is more than 7 million times more than that of the guidance computer.
The iPhone's processor runs at approximately 2490 MHz, making it over 100,000 times more powerful than the Apollo 11 computer, which ran at 0.043 MHz.

The Texas Instruments TI-73 calculator, released in 1998, had slightly less ROM but eight times more RAM than the Apollo guidance computer.
The TI-84 calculator, released in 2004, had 32 times more RAM and more than 14,500 times more ROM than the Apollo computer.
The calculators, designed for students, were more powerful than the computer that landed man on the moon.

With modern software development tools, the software development time would have been significantly faster.
The user interface would have been easier to use, potentially reducing stress in critical situations.
