People often email me questions they could have answered with ChatGPT. I just copy-paste the question, copy-paste the answer. This isn’t new. From 1998-2005, I used to do this Google searches. Even people who have Google Maps on their phone ask me for directions. I pull out my Google Maps and tell them. They don’t even get the sarcasm. Effectively, I’m the Human-as-an-Interface (HAAI everyone!) But I learnt today that this has historical precedent. Doormen, lift operators, doormen, the waiter who recites the menu, the secretary we used to dictate to, … ...

In reality, a colour is a combination of light waves with frequencies between 400-700THz, just like sound is a combination of sound waves with frequencies from 20-20000Hz. Just like mixing various pure notes produces a new sound, mixing various pure colours (like from a rainbow) produces new colours (like white, which isn’t on the rainbow.) Our eyes aren’t like our ears, though. They have 3 sensors that are triggered differently by different frequencies. The sensors roughly peak around red, green and blue. Roughly. ...

Video demo of Sony’s digital desktop. This converts your physical desktop (you know, the one where you keep paper and staplers) into a digital desktop. You can drag and drop on to the physical desktop. You have to see it to understand!

Nilesh on the Uncanny valley. The point at which a simulation becomes close enough to reality that it stops matching up. I have seen a lot of this happen in software design too.

Apologetic software.

Cool picture of a virtual keyboard. The article talks about a purely optical keyboard. You move your fingers, and the “keyboard” detects what you’re typing. Now, if optics are that advanced, they should be able to figure out what I’m writing and put that on the computer. So I won’t need a digital pad – I’ll just write on paper. Or even better, project the screen! Then I’ll just carry a little 1" x 1" x 1" box that’ll project a virtual screen that I can draw / write on.

Chatting with your computer – the new way of interacting with your DOS prompt.

It’s possible to type with your eyes. Hope this is commercialised soon. The details are available for free.

I always felt using voice to communicate with computers was a bad idea. In my case, it’s more because speaking takes up a lot of energy. But looks like it takes up a lot of thought power as well. Maybe speech recognition is not such a good idea.

I’ve been reading a lot about augmented reality lately.

MIT is doing some interesting research. (The Erotic Computing Group)

Cybelle lives in AgentLand. She’s 100% virtual (having admitted it, she asked if I was disappointed), and guides people through their site. It’s a new and interesting way of having a search engine on a site.
