Using Apple Vision Pro on a walk and in a car

Wearing Apple Vision Pro at Naju Lake Park out of Travel Case

One of the main reasons I developed a wearable computer two decades ago was to have a computer available for use while on the move. Since Vision Pro is also a computer you wear on your body, I wanted to see if it was just as versatile. So I brought it to a local park in the Travel Case and wore it at a bench as you can see above. The wearing process itself took about 90 seconds to complete, which isn't that different from my old creation.

I can "touch" the buttons or make gestures to interact with the floating windows

Once the system is booted and ready for use, I can load up the Home View and launch apps, all of which are floating but "anchored" to the surrounding space. Although the default way of interacting with the elements in a window is via hand gestures, I can just walk up to the window and "touch" it to use it like a huge touchscreen. There's no haptic or tactile feedback, so it's a bit awkward. However, the audible cue does make you feel that there's a slight feedback and it helps.

Picking up and unboxing the Apple Vision Pro

Arriving at an Apple Store in Los Angeles on the launch day of Vision Pro

Apple launched its first so-called spatial computing device called Vision Pro on February 2, 2024, only in the United States. As someone who had keen interest in wearable computers for quite some time, and is big fan of all things Apple, I had to get my hands on a set. So I was able to make it to Apple The Grove in Los Angeles on the launch day and do just that.

Asiana Airlines flight OZ202 made a U-turn 2 hours and 30 minutes in

The trip wasn't easy, as the plane I took had one of the passengers falling ill mid-flight, causing an emergency landing in Tokyo Narita Int'l Airport and making the trip 6 hours longer than originally planned. Thankfully, I was able to arrive at the store before closing.

First sunrise of 2024 from Bitgaram City

Sun rises over Naju Bitgaram City on January 1, 2024

2023 had been another interesting year. In terms of travelling around the world, things have gotten almost back to the levels of pre-pandemic levels. This allowed me to visit many new places as well as revisit some old ones. But for watching the first sunrise of the year, nothing is more comfortable than doing it right at home. Thankfully, skies were almost totally clear, allowing my phone to capture the scene with clarity. Like the photo, I hope everyone has a bright year ahead of you.

For the full 12-minute progress (sped up 4 times) of the sunrise, check out the video that I uploaded.

Testing the new iPhone 15 Pro with Harvest Moon

Cameras of the iPhone 11 Pro, iPhone 13 Pro, and iPhone 15 Pro

I went to San Francisco to pick up my iPhone 15 Pro on the launch day, September 22, 2023. The primary advantages of this model over the previous ones are USB-C support and reduced weight. Unless you were getting a Pro Max version, the camera on the Pro series did not get much of a hardware improvement. So when I decided to do some comparison shots with the Harvest Moon photography during the Chuseok holidays, I chose some older models - iPhone 11 Pro and iPhone 13 Pro.

The Moon shots on September 28, 2023 taken with iPhone 11 Pro, iPhone 13 Pro, and iPhone 15 Pro

There were expectedly some notable quality differences between the three models. While iPhone 11 Pro does have a three-lens setup like the rest, the telephoto lens is only capable of 2x zoom. As a result, the size of the Moon in the photo was the smallest and least detailed. Both iPhone 13 Pro and 15 Pro have the 3x zoom lens on them, but for some reason the 15 Pro shot a consistently sharper image. Perhaps a slight hardware and software processing differences were at play. In the end, the latest was indeed the best.

Further details of the shooting sessions have been outlined in a separate video.

Celebrating Bolt EV's 5th birthday

Bolt EV on its 5th birthday in June 2023
My Bolt EV has turned five this month, as it racked up more than 130 thousand kilometers on its odometer. It's fairly efficient and low maintenance, so I'll keep driving it as the primary vehicle for several more years. It definitely has some downsides like the poor fast charging performance, but I've gotten used to it. Let's see how it's been doing all this time. You can watch the YouTube video or keep reading below.

Monthly performance trend from June 2018 to May 2023
As you can see here, I generally drive about 1,500 to 2,500 km every month, for an average of 2,179.3 km. Lifetime efficiency is at 7.72 km/kWh, but it can get as high as 9 km/kWh in summer or drop to about 6.5 km/kWh in winter. As for the battery, it had been degrading stably for the first four years, then it was replaced with a new one. Interestingly enough, not only is the usable capacity larger by about 3 kWh, it's maintaining its capacity better than the original one. I'm going to be looking into this further at at later time.
