Quick Thoughts on Apple Watch

While I’m still unsure on what wearables should actually do, I managed to get some photos of the Apple Watch. Unfortunately I wasn’t really able to find any units available for a hands-on, and as far as I can tell it wasn’t possible to actually try any of the software yet. However, based upon what I’ve seen Apple brings at least a few great ideas to the table. The digital dial/crown is definitely one of them, as it opens up the door to all kinds of new possibilities for navigation that are currently either impractical or impossible for wearables that don’t have this hardware feature. In addition, Apple’s strong emphasis on personalization with two sizes, three editions, and six watch bands is something that all OEMs should pay attention to. Finally, the dedicated SoC for the Apple Watch is something that is absolutely necessary to enable a good user experience as space is so critical on these wearables. There’s also no question that Apple has done a great job of focusing on industrial and material design, as it looks like all three versions of the watch have premium materials and excellent fit and finish. While it isn’t clear what display is used, it seems likely that it’s an OLED display judging by the amount of black in some of the watchfaces, although ambient lighting in the demo area made it hard to tell whether this was the case.

However, my reservations are largely similar to concerns that I have with all wearables. Ultimately, the Apple Watch must provide utility that’s strong enough to make me turn around and get it if I forget it. As-is, I don’t really think that even the Apple Watch has that level of utility, even if it is excellently executed. Of course, this is also based upon a demo unit that I wasn’t able to touch or use.

Of course, a few concerns remain, mostly in the area of battery life as it seems that only the Pebble line of wearables can really deliver enough battery life to not worry about charging a wearable on any sort of regular schedule. At any rate, I’ve attached a gallery of photos below for those interested in seeing all the various combinations of watches that Apple will make.

IDF 2014: Intel Demonstrates Skylake, Due H2’2015

Taking place this week alongside the consumer electronics clamor is the annual Intel Developer Forum (IDF) at the Moscone Center in San Francisco. Though it has and continues to be first and foremost a developers conference, IDF also offers Intel a chance to unveil new products, and in more recent editions discuss and promote their plans for further breaking into the mobile market.

Diving right into the subject of Intel’s Core microarchitecture, with the Broadwell based Core M already in the process of launching, Intel is giving developers and the public a look at what comes after Broadwell. Already on Intel’s roadmaps for some time, Intel took to the stage at IDF14 to formally announce their next-generation Skylake architecture and to demonstrate its status.

Intel’s Tick-Tock Cadence
Microarchitecture Process Node Tick or Tock Release Year
Conroe/Merom 65nm Tock 2006
Penryn 45nm Tick 2007
Nehalem 45nm Tock 2008
Westmere 32nm Tick 2010
Sandy Bridge 32nm Tock 2011
Ivy Bridge 22nm Tick 2012
Haswell 22nm Tock 2013
Broadwell 14nm Tick 2014
Skylake 14nm Tock 2015

In Intel terminology Skylake is the Tock to Broadwell’s Tick, offering a new microarchitecture atop the 14nm process first introduced with Broadwell. As is the case with every Core update, for Skylake Intel is shooting for significant increases in performance, power efficiency, and battery life. Since Skylake is built on the same 14nm process as Broadwell, Skylake is primarily an exercise in Intel’s architecture development capabilities, with its gains needing to come from optimizations in design rather than significant manufacturing improvements.             

At roughly a year out from launch Intel is not saying anything about the architecture or design at this time, but they are using IDF to showcase that Skylake is up and running. Demonstrating this, Intel showcased a pair of Skylake development systems. The first of which was a traditional open laboratory testbed that was running 3DMark, which was being used to showcase that the GPU and CPU portions of Skylake were running and performing well. The second demonstration was a completed laptop that was playing back 4K video, and is an early version of the hardware Intel will be shipping as the software development vehicle for developers next year.

Alongside their demonstration, Intel also announced a rough timeline for the volume production and availability of Skylake. Volume production will take place in H2’2015, with product availability slated for later in the year. With Broadwell being behind schedule due to a slower than planned bring-up of their 14nm process, there has been some question over what would happen with Skylake and Intel clearly wanted to address this head-on.

Consequently a big part of Intel’s message on Skylake is that the next generation CPU is already up and running and is in a healthy state, apparently unfazed by the earlier 14nm delays that dogged Broadwell. At the same time the H2’2015 launch date for Skylake means that it’s going to be out roughly a year after the first Broadwell parts, which means Intel still intends to adhere to their roughly 1 year product replacement cadence.

Understanding Dual Domain Pixels in the iPhone 6 and iPhone 6 Plus

Understanding Dual Domain Pixels in the iPhone 6 and iPhone 6 Plus

In the launch announcement, Apple announced that their new display had dual domain pixels, which improved viewing angles. Unfortunately they dropped the subject at this, which make for a lot of room for confusion. Anyone that does a cursory analysis through Google will only find references to this type of display in monitors for medical use or similarly technology used by IBM monitors.

However, dual domain pixels are actually not as complicated as they seem. In fact, this is a display technology I remember seeing with the announcement of LG’s AH-IPS technology back in 2011. For those interested in the technical definition, dual domain pixels refers to the fact that the electrodes in the pixels aren’t all aligned. Instead, they’re skewed when viewed from the perspective of the lines defined by the rectangular edges of the display. Because these subpixels are skewed, it’s possible to compensate for uneven lighting that occurs because each individual subpixel is viewed at a different angle, which causes a change in color and a faster fall-off of contrast.

At any rate, this is easiest to explain with a photos. Above, we see the pixel layout of the iPhone 5. This is the standard rows/columns of pixels, and not really news to anyone that knows how displays work. Let’s look at a dual domain arrangement next.

Anyone that has tried the HTC One (M7) or One X will probably understand the effect of this change as these phones have had this type of skewed subpixel format to get better viewing angles and less color shifting with changes in viewing angles. This can carry some risk though as black backgrounds may have some color shifting towards purple instead of yellow/blue, which can look strange but is quite subtle in my experience. There’s really not too much in the way of disadvantages, so I look forward to seeing how Apple’s new displays do in our tests.
