Reviewing a BenQ “eye-care” monitor

It is quite timely that monitor manufacturer BenQ has just sent me their latest bit of kit to review. It is a 27-inch (68 cm) “eye-care” monitor. The device boasts that it addresses many of the problems facing home workers such as long periods of use, bright rooms, non-ideal environment and placement of monitors in home offices and so can help reduce the risk of eye strain, dry eyes, headaches, poor posture and neck and shoulder pain, and other problems some computer users face when using inappropriately sited monitors. There is mention of problems specifically associated with blue light from screens and monitors.

Having almost settled in with new digressive reading glasses – head-up focus at PC distance, eyes down focus for paperwork on the desk or phone, I was intrigued to see how it would feel to use such a monitor. On a point of order, I used to get awful headaches in my first publishing job working with paper manuscripts and proofs and accessing a mainframe computer via a VT100 terminal (one of those awful green light things). This was 1989, long before the web and although we had email and a database nothing was graphical in that office. Anyway, no headaches and no residual eyestrain almost thirty years later. So I’d no real need for a monitor that would reduce eyestrain but nevertheless willing to give it a go…

From the information, the monitor has “Brightness Intelligence”, detecting ambient light levels and colour “temperature” of surroundings and adjusting its output accordingly. It has different levels of blue output, specifically too, for different working conditions. I assume these can be overridden when one wants to calibrate for true colour work – photos, graphics, video editing, for instance.

The monitor is also flicker free (although I don’t think I’ve ever noticed flickering on any monitor I’ve used over that last three decades even with that old VT100 terminal). Maybe I am not consciously sensitive to that kind of flickering, although overhead mercury tube fluorescent lights do sometimes make me nauseous. My contact at the company suggested revealing flicker on my old monitor and the review monitor using a smartphone video capture. But, I am not entirely sure what that would prove other than the inadequacies of smartphones and frame refresh rate. If you don’t perceive/see an issue, then it’s not really an issue in this case.

An extra feature that I have not seen in any other monitor is smart focusing whereby the Window being used at any given time is highlighted more than other windows. How this works when one is working with side-by-side documents remains to be seen. Although the choice to focus on a given window is made by the user at any given time. However, my contact at BenQ tells me this is a function aimed at those watching video in a given window.

The eye-care monitor also has a High Dynamic Range (HDR) which means detail in the blacks and the highlights is more akin to how we perceive the world around us rather than the compressed world of photos and images, where very dark greys become smeary black and off-white highlights are simply blown out, as photographers would say. There is a greater colour palate than might ordinarily be found in a TV screen. That makes the computer monitor more suitable for high-resolution video rendering, and for 4K HDR gaming consoles than a lesser TV. Technically, the monitor boasts three times the contrast than normal panels, 33% greater brightness, and up to 93% DCI-p3 colour coverage. It can be setup for improved “eye-care” and for those who need high-quality video, graphics, photo editing and processing.

I am not entirely sure why the panel has a standard that makes the top lean forward further than the bottom of the screen, but more to the point there is no universal fixing bracket so I cannot install it on my adjustable cantilever desk arm and set it at the perfect height and angle for my posture and the way I work.

However, for me personally, there is a more problematic issue with such a large screen regardless of the quality or eye-care features. My new spectacles. They are digressive, which means when viewing something about 60 cm away straight on the view is nice and sharp but a movement of the eye left or right up or down as one might do frequently with a 68 cm monitor means that there is some distortion across my field of vision because the lenses are designed to focus closer towards the lower edge and indeed upper and lateral edges. Someone with 20:20 vision, or presumably conventional reading lenses, would not suffer this effect, but I am not sure I can work with the need to move my head so much to maintain focus, when I am used to a much narrower computer monitor, albeit with the same resolution. Of course, BenQ makes monitors from 21.5 to 32 inches in this range, so maybe there is a model that would suit my new specs.

The monitor is specifically a BenQ EW277HDR, which seems to be billed as a “video enjoyment” monitor elsewhere in the monitor market rather than focusing on the eye-care aspects.

Is it okay to kick a robot?

UPDATE: One of their robots can now dance, which is the way forward, please don’t weaponise them, just let them twerk and moonwalk

These robots can now open doors for each other and let themselves out…just sayin’

By now, you’ve probably seen the astounding quadruped robots that have been built and demonstrated by Boston Dynamics. These machines run like four-legged animals and don’t seem to mind when their human companions give them a kick…hold on…give them a kick? Is that really the best example to set impressionable people watching the videos?

One could argue that it’s a machine, it doesn’t “mind” being kicked, if that demonstrates just how robust the software and servos are to disturbances in the forces around them. But, it is still quite a disconcerting thing to see. The next generation might be togged up with heads and fur, for instance, to make them look even more like animals, that would make for even more uncomfortable viewing, I reckon. And, then, of course, ultimately, such a robot might be endowed with artificial intelligence, sentience, even. Would kicking a bot that knows what you’re doing be moral?

This also raises another question. If we build sentient robots, would it be sensible to give them pain receptors? Would we want them to know to avoid things that might hurt. And, Asimov aside, might a robot in pain having been kicked feel that retaliation was the ethical thing to do from its perspective?

Asimov on the three laws of robotics

Laws of Robotics are essentially the rules by which autonomous robots should operate. Such robots do not yet exist but have been widely anticipated by futurists, novels, in science fiction movies and for those working in or simply interested in research and development in the fields of robotics and artificial intelligence are important pointers to the future…if we are to avoid a Terminator or Matrix type apocalypse (apparently). The most famous proponent of laws for robots was Isaac Asimov.

He introduced them in 1942 in a short story called “Runaround”, although others had alluded to such rules before this. The Three Laws are:

  • A robot may not injure a human being or, through inaction, allow a human being to come to harm.
  • A robot must obey the orders given by human beings, except where such orders would conflict with the First Law.
  • A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

Here’s the man himself discussing the three laws:

Grant a pardon to Alan Turing

UPDATE: Finally getting around to updating this page, it is ten years since Alan Turing was granted a posthumous pardon (2013)

A new petition is now online seeking a pardon from the UK government for mathematician Alan Turing. In 1952, he was convicted of ‘gross indecency’ with another man, under an archaic law that no longer exists. He was given so-called “organo-therapy” (chemical castration) and two years later, killed himself with cyanide-laced apple, aged just 41.

Turing invented the concept of the modern computer, devised the first real test for artificial intelligence and cracked the German codes to help bring WWII to an end.

Turing also figured out how the leopard got its spots and what makes zebras stripy. Seriously, he figured out that the diffusion of cyclical chemical patterns in the growing embryo, particularly in pigment cells would give rise to waves or rings of different pigment across the skin.

The 5 Ws (and How) of writing for the Web

Steve Buttry presents the five six questions that should guide your reporting as you interview, observe and research to gather the facts for a story, whether that’s live tweeting from a conference, a facebook update, a blog post or your first long-form feature for an online magazine.

They can, he says, also raise ethical issues you should consider as well as helping you home in on links, graphics and people with which to build your article.

Google doodle celebrates vitamin C discoverer

Google doodle celebrates vitamin C discoverer – Today, Google celebrates the birthday of Hungarian physiologist Albert von Szent-Györgyi de Nagyrápolt (September 16, 1893 – October 22, 1986) who discovered vitamin C and the components and reactions of the citric acid cycle. He was awarded the 1937 Nobel Prize in Physiology or Medicine. He was also active in the Hungarian Resistance during World War II and entered Hungarian politics after the war.

New Facebook friends and blogging advice

If you’ve been on Facebook for any length of time you will have had friend requests from people you don’t know. That’s fine. Often they’re just spammers. Sometimes, they’re users with whom you might have a few friends in common. If paths haven’t crossed I usually redirect requests to the Sciencebase Facebook page instead of automatically accepting the request. Occasionally, the new wouldbe friend turns out already to “like” the page, says so and starts a conversation. Also fine. Half proves they’re not some kind of bot. Virtual friendships can spring from such occurrences. It’s what this social media lark is all about, right?

Indian medical blogger Pranab Chatterjee who runs Scepticemia, sent me a friend request and I went through the process described above and he pointed out that he already liked the fan page, was surprised to learn I also run Sciencetext and wondered how I manage to juggle so many words at once. He also thought that I might be able to offer him some advice on boosting visitors to his blog as he felt like it had reached a plateau. He wanted the recipe for my secret sauce of success…well I don’t have one, I just work (probably too) hard and hope for the best. So, I turned the tables on Pranab and asked him what I could do to improve my blog.

He was a little taken aback, but offered some encouraging words about the liking the clean look of the blogs and putting in a request for more hardcore medical posts, he’s a doctor, hence the interest. I do write about medical matters, but I will probably leave the hardcore stuff to the hardcore medical bloggers (and I don’t mean Dr G)

Anyway, if there is a recipe for blogging success, other than going black hat it has to be plenty of persistence a wadge of hard work, and perhaps a very strong background in the subject on which you’re blogging coupled with experience in the wider journalism industry and/or experience in science (or other field) and the conference circuit. I think enjoying writing probably helps as does have an analytical approach. Being active in social media, particularly Facebook and Twitter seems to help raise one’s profile although is not really reflected in traffic, in my experience (a few hundred to a thousands new visits extra each week, perhaps) and the occasional spike. Others might perceive that differently, but more than 80% of Sciencebase traffic is still search engine derived. Nevertheless, make sure every new blog post is as perfect and precise as you can, and then tell your Facebook followers, twitter crowd about it. It’s also always worth doing a spot of whitehat SEO, just to improve search traffic benefit.

That’s just a few, almost random thoughts. Bottom line is: if you enjoy writing, you probably should have a blog. If you enjoy people you probably should make friends.

Scientists and social media

  • Science and social media – It may seem counterproductive for scientists to air their dirty laundry in public, but in a world where the media is dominated by manufactured pseudo-debates over the reality of anthropogenic climate change, the safety of vaccines and evolution, the value of giving the public a window into what a real scientific debate looks like cannot be overestimated.

New Sciencebase element

I’ve updated the Sciencebase tumblr account, for those of you who would like an alternative one-stop shop for science and technology news and views from David Bradley. The site aggregates the Sciencebase, Sciencetext, SciScoop, and Reactive Reports newsfeeds as well as my “likes” in Google Reader.

To celebrate, I’ve created a new element icon and based it, this time, on an actual chemical element mashed with the tumblr floral logo.

sciencebase delicious bookmarksIn case you missed it there’s also a sciencebase elemental delicious icon floating around on the site somewhere. The links I bookmark in delicious usually include science and technology posts and news items that catch my eye at random times throughout the week.
