Touchscreen Problems (Zombie Finger)

32 Replies Jonny Hankins

iPad zombie finger - Touchscreen ProblemsOver the last couple of weeks I have flown from the USA to Britain, then to Italy, and back finally to the USA. I flew on some lovely new Airbus aircraft, but had a constantly recurring problem with the on-board entertainment systems.

The problem is that in the seat above me there is a fantastic touchscreen entertainments system, but my fingers do not work. My son who was sitting next to me has good fingers, he touches the volume section and can turn the sound up or down, but I cannot because the slider does not seem to recognize my body.

So it must be my screen I think, my son leans over and it works perfectly well for him. We swap places, now mine works for him but I still cannot change the volume, this time on a different machine.

It must be me I conclude, but why? Long ago I gave up using anything touchy for this reason. I try licking my hands, warming them up, cleaning the screen but I do not make any progress. So I started looking around the web for some answers to find that I am not the only one, hurrah. There is even a recognized name for the problem in some fields, Zombie Finger!

Touch screens operate in many different ways. At Walker Mobile you can download a free PDF that explains how the different technologies work, but the vast majority of application that we know use one of two approaches. They can be described as Resistive Touch and Projective Capacitance.

Resistive touch is old school analogue. Two surfaces are together, typically one of glass with a thin film over it. You push down on the film and it makes a circuit using a grid of electrical conductors. The system is cheap but being mechanical liable to damage and wear, and it is thick.

Projective Capacitance has no moving parts however, and some of its advantages mean that it is rapidly taking over the market. It is a system that works on capacitance, which is the thing that gives you a shock when you walk over a synthetic carpet and then touch the brass door handle in the hotel that you are staying in.

iPhone touch screen technology

How iPhone touch screens work.

Again there are two layers, both charged but to a different extent. When you touch the screen some of the charge is released into your finger, and this tiny change can be measured. And here lies a variable, because the nail will not carry a charge, gloves stop the action and so I wonder if even the state of the skin at the end of the fingers might effect usability. Do I type too much? No charge transfer means no volume.

For a fuller explanation of these 2 competing systems see this article, it is short but extremely informative. I would just like to know if anyone else has issues with touch screens, and if so if they have been able to address the issue in some way. As technology advances this interface is becoming the norm, and we wouldn’t want to leave people with particular skin types behind now, would we?

SEO – becoming a victim of your own success

If you succeed, others copy you. Some say that this imitation should be seen as flattery. Those who are being imitated may just think you are being plain darn rude.

This is a story of how I had an idea, and that idea trued into an overnight success – with yours truly receiving nul points for it.

Okay, I am over dramatising things here.

SEO

Quite ironically, one of the toughest industries to succeed in is SEO, as the market is hugely over saturated with literally tens of thousands of people and firms, offering their services to help you “reach top of Google” or rank “on page 1 for your keywords” – believe what you will. Food for thought: Google the term ‘SEO’, and there are (to quote Google) “About 224,000,000 results“. Who is top? No, not the best SEO agency, but Wikipedia – naturally!

My Success

Anyhow, the story goes that I had an idea, an idea to make a new image for an article. One of our writers had contributed a guest post, and in that article they talked about SEO. I thought that an interesting image to accompany the article would be an upward pointing arrow (to demonstrate improvement) and the word ‘Google’ balanced on top.

I found an image off the internet, and took Google’s logo for the text, and set about making a large, high quality version of my idea.

The image I created can be seen below.

SEO Graph - GoogleQuite a good image I thought. Apparently, other people like it to. After just 4 months being live on the blog, many other people have found it in Google, and the image now ranks in the top 25 images when you Google Image Search the term ‘SEO’, and the top 10 when you type ‘Google SEO’.

Okay it ranks on an image search, not a ‘web search’, however I still got an image of my design and [part] creation, very high in the SERPs for a very difficult keyword.

The Problem

The problem was the aforementioned popularity. As I opened: “If you succeed, others copy you” – it’s true.

After just a few weeks of the image being live, it had been copied, and Technology Bloggers (the image source) was no longer the site that showed up with the image, as other sites with higher reputations (in Google’s view) stole our limelight.

As the images creator, I believe that when people find the image in Google and then click on it, they should be taken to our site, as without this site, there would have been no image! However we don’t show anymore.

Stealing Images

This lead me to think about stealing images. I was unhappy that other people were taking my work and passing it off as their own, and benefiting more than me because of it.

However who am I to moan, as I steal images too. If I like an image I will use it in an article. Is this right? Possibly not.

Ideas lightbulb

The ‘light bulb’ image I used in my post yesterday.

That said, when using images, I tend not to lift the image straight off a website and put it in my post, I will usually modify it in some way first, so that the image is different from the creators version. I feel this is slightly more justifiable than just ‘stealing’ another’s work.

Take the image in my post on Monday, the idea light bulb, that wasn’t my image, but I resized it and added some text to it – therefore making it a variation, not a copy.

In my Google SEO image, the SEO graph image was an origional image, as was Google’s logo; neither of these images belonged to me, but I still used them.

Right and Wrong

I feel that straight out lifting and pasting images is wrong, and anyone who has ever suffered because of my use of their image, I apologise, get in touch and I will see what I can do.

If you modify an image in some way to make it your own, then I feel you are in a slightly different position.

The Fight Back

As you have probably gathered by now if you are a loyal reader, I [sometimes] have a mild case of perfectionism and am one to constantly tweak, change and improve.

After a while I started to dislike the image I had made; the letters were a little skeewiff and the shadow at the bottom finished a little abruptly.

So I went back the the drawing board and remade the image, but better.

I knew if the last image was successful, and this one was better then it would probably be more popular and therefore shared even more, so I hatched a plan. I decided to watermark the image, very faintly, with Technology Bloggers web address. I don’t really like watermarking much, but it seemed to be the only option I had.

Below is the new image.
Google SEO ChartNotice that there is no watermark on the smaller version of the image, however if you click on the image, the big version does bear the watermark. If you want to use a small version, fine, no problemo. If you use the big version, you advertise our site – simple. That way, if the image is stolen, all credit is not lost, and hopefully, Technology Bloggers should show in the search results for the image, as we have the biggest version hosted on the site.

UPDATE: I have updated the SEO image again! Click the link to view the new version. 🙂

What renewable energy will you be looking into?

8 Replies Stephen Kenwright

The recent government incentive to promote ecological mind sets in the home is good news for the environment. Householders will be offered loans to deck out their homes with energy-saving appliances and equipment, including extra insulation and new boilers.

So what exactly do you need for your home?

Loft Insulation

If you’ve no loft insulation in your house, you could be losing up to a quarter of your home’s heat through the roof.

Most newer buildings are built to a standard taking into account this loss, but if you have a home that’s a little older, chances are you’re wasting all that lovely warmth and putting yourself out of pocket.

The Green Deal will provide owners of uninsulated homes the chance to reduce the energy used in heating by proving loft insulation.

Wall Insulation

You could be looking at losing up to a third of your home’s heat through uninsulated walls. Cavity walls are much more energy efficient than the solid walls of older houses, and if your home was built before around 1940, it’s more likely to have the latter.

With good wall insulation, you’re looking at making a real saving in energy bills so it’s a good idea to find out if you’re equipped to keep all the heat in your home.

Boilers

According to energy efficiency ratings, a band A boiler is 20% more energy and cost effective and a band G one. It’s usually the older boilers branded with the G rating.

If your boiler is outdated, you could be losing a lot of money from it. Modern, band A boilers have an energy efficiency rating of 90% and allow you to keep much better tabs on your energy use. It’s worth investing in thermostatic radiator valves so rooms that aren’t being used aren’t heated too.

Katy Jones at Dulas had this to say of the feed-in tariff scheme:

“The feed in tariff incentive from the UK government is encouraging many people to consider installing renewable energy technologies; it will naturally mean that some renewables companies also look to offer energy efficiency measures as part of their product portfolios.”

One single wind turbineProducts which will include solar panels. Fitted onto the roof, solar panels are capable of generating renewable energy for the home. And if they are producing more energy than your household needs, you can sell that energy back to the National Grid.

“From our perspective,” Ms. Jones continues, “Solar PV is a viable, cost effective way to generate free electricity and is especially good for high energy users looking to reduce their energy costs or with Carbon Reduction Commitments to meet.”

Other renewable energy sources will include micro wind turbines, which will be accepted on the Green Deal. Though they are a little small to provide all of your energy, it’s the little things that make a big difference to an energy bill.

With the government backing you, it’s never been a better time to look into renewable energy.
