l was in a meeting recently with a large group of executives from one of Australia’s biggest companies. Half of the executives had iPad, (tablet envy anyone? ). Early in the meeting as l was feverishly taking notes on my tablet pc (Active digitizer of course). One of the execs turned to us and said,

"Wow, you really use those things don’t you!"

Interestingly none of the 7 iPads did anything during the meeting. Why?

This is not an isolated experience. I observe it all to often. Every plane flight l take lately, l get up and have a scan around to see what the iPads are doing… I’m yet to see one doing work on any of my regular flights. I’ve seen plenty of solitaire though…

In the meantime I used my last 3 hour flight to process 250 emails… Contacts created, appointments calendared, meetings requested, emails sent, spread sheets analysed. Perth to Melbourne seems to go in about 5 mins thanks to my Tablet PC and the power of the Active Digitiser Pen!

What my experience tells me is that even the slickest touch experience cannot come close to accomplishing what the Digital Pen can. Touch input is blunt, slow, frustrating and dumb. The only thing it has is convenience. That’s good, but it’s not enough alone…

Active Digitizer = Heavy Lifting

For a science / education perspective on why active digitizer technology is still the best method of input for real work, check out this article from John K. Waters. – Style, but no stylus.

I should add of course that I own an iPad amongst dozers of touch tablets. I’ve also been working with touch input for nearly 20 years now, and the last 10 with tablets and PDA’s – In other words, I’m no stranger to what’s possible!

Some hardware vendors try to pass off daylight readability in terms of brightness, and brightness is measured in nits. So you might see a claim like “500 nits outdoor display.”

We all love to measure things with numbers, but nits is not a good measure of daylight readability.

Simply cranking up the brightness with a stronger backlight on a display causes a number of issues:

1. Significantly reduced battery life
2. Washed out colours
3. Low contrast

The very best solution is actually a display that is readable on little to no brightness on.

In other words, the more readable it is with the least possible nits the better. To achieve the best outdoor readability, you need to address:

• Reflection – Minimising sunlight reflection with Anti-reflective screen coatings
• Diffusing – Reflective, transmissive and transflective technologies work to diffuse light out effectively
• Viewing angles – some achieve up to 180 degrees in all directions, so you can read the display easily at any angle
• Contrast – This is the true benchmark of daylight readability.

According to Rugged PC Review, the effective contrast of an outdoor display is:

1 + (emitted light / reflected light)

So if the reflected light is high, the emitted light needs to be higher just for the screen to be readable.

Getting reflection, diffusion, viewing angles and contrast right can mean that your display is readable outdoors with very little brightness to speak of.

The new motion J3400 is by far the best example of this. As we demonstrated in our product video, you can actually read this display in direct sunlight on the ZERO brightness setting.

That means that you can go out into the field and run much, much closer to the manufacturers claimed battery life of 7.5 hours.

The J3400 is actually the best outdoor readable screen that we’ve seen on a Tablet PC by far and it sports only 320nits. 

A display that has to run at 1000nits to be viewable will of course, not be so good on batteries. So if you have to sacrifice hours in the field just to be able to read the screen, how daylight readable is it really?

Email – meet Tablet PC

With a Tablet PC and Office 2007 (or Office 2003) you can send email in handwriting. That enables you to send emails from places like:

• An airport lounge
• A doctors waiting room
• A cafe over coffee

Tablet PCs allow you to maximise your working time by enabling you to use a fully functional PC in places where you generally wouldn’t use a laptop.

Brush up your handwriting skills, because you’re going to need them again. Tablet PCs are great productivity tools.
