We often confuse sensation and perception.
Think of the camera obscura. There is nothing but light which is making the image on the wall. Or think of a video camera attached to a video screen. The camera captures the light external to it, turns it into data and turns that data in to the video image on the screen. It does not “think” about the image. It does not “have an opinion” of it. It simply reproduces it.
The eye does the same thing. It captures light eternal to it, turns it into data and reproduces that in your brain. Until then it does not “think” about the image. Thinking occurs after that data is received. That raw data is sensation. The processed data after reception is perception.
If you are still not convinced then this talk by Sheila Nirenberg about her research on the prothetic eye is an excellent real-world demonstration of what sensation and sense data is.
A track pad is a track pad is a track pad. Not.
Take the Apple MacBook Pro 2015 and the Microsoft Surface Pro 2018 – they both have touch or track pads. But on the MacBook pad is fixed. This might sound ridiculous and unusable but really it means that there are less moving parts and less likely to break. The workaround for this is an incredible haptic feedback system which taps back against your finger making it feel like some kind of movement. The illusion is simply quite amazing. The Surface Pro still uses a traditional traditional track pad. While it has become multitouch like most of today’s devices it still means it feels old. The verdict – MacBook‘s track pad is simply an experience. Unless one uses tries similar but different things one does not know the subtle differences between them. Direct experience is important, in every sense.
It would be nice if tomorrow I would woke up and a different US president was in the White House. But because there is one reality I have to be content and continue with it.
It would also be nice if I woke up tomorrow morning to find I am a world famous scholar with three important books on my resume. Again, that would not be the case. I must work for those. Sigh.
I am in no doubt that there is only one reality, and it exists with or without being perceived. For this reason perception colours reality rather than changes it. Different perceptions (not different realities) are the root cause of all misunderstandings.

So Apple announced its new products today. Why do I care? Considering the amount of time I spend on my phone, the amount I use it for photography, productivity, entertainment, etc, it makes sense that I invest in it. It is the primary technology I use because if its usefulness. It is my main camera and Filofax. I blog from it more than I blog from my computer. I entertain myself with chess and watch live broadcasts from it. I reply to emails and messages from it because it is more convenient and efficient to do.
The new iPhone Xs and Xs Plus is nice but it isn’t worth a replacement for my X. The Xr however is worth it as a replacement for my wife’s old iPhone 6s, which was originally mine. It looks like Apple is moving towards to phase out Touch ID in favour of Face ID by not introducing iPhone 8s at this time.
While I can see that they will probably bring out the 8s later as their low end model (phasing out their iPhone 7), eventually they will do away with it also. Furthermore, people still love the Touch ID. It is a slick piece of security that had little fault. I liked the fact that multiple fingerprints of more than one person can be registered. I had access to my wife’s phone by registering mine. I couldn’t do that with Face ID, which allows only one face as ID.
Overall, the Xr is a good replacement/upgrade for the 8. Keeping the LED display, but upping the camera, security features, size and a new A12 Bionic chip (which is supposed to be much faster than the previous A11 Bionic chip in the X).
