Re: resolution preferences??

2008-06-10 Thread Ilja O.
I'm sorry to break into your nice flamewar, but I've just wanted to ask:

pro-QVGA people, are you serious?

In two years (yep, that's when GTA03 will be released judging by GTA01-02)
QVGA will be just like floppy drives on notebooks - totally non completive.
And won't be because everybody *really needs* =VGA resolution and can't
survive with lower one. It will be just because everybody on the block is
hi-res. Same thing happened lots times in IT: remember ATA to SATA switch?
Do you really think that home users wouldn't be able to stick with good old
ATA?

Quard core processors?
New sockets?
Usb 2.0  1.1 ?
You think that we couldn't live without these upgrades?

Making fonts bigger via lowering the screen resolution is total nonsense.
And hi-res tranflective screens will be available in less than a year.

Btw, QVGA won't cost much less (it doesn't now and in two years it could be,
in fact, more expensive than VGA).

That has been especially true of flash drives - I remember seeing a
16MB flash drive that cost more then the same 32MB model.

The only reason for me considering the Freerunner is the VGA display. I don't 
car much about videos on portable devices, but I want a sharp large screen for 
navigation (maps), browsing (www), reading/composing (email).

If people want video devices they can get plenty devices out there, but there 
is no device available with the display specs of the Freerunner. Keep it that 
way!

 When I first saw the Neo's screen I was amazed by how crisp the
 graphics were and the shine on the Openmoko logo looked real to me.  
 The
 first thing I tried was the terminal (of course) and I was happy that
 the text could be zoomed, and was still readable. I am short sighted
 and have seen the graphics on the iPhone and they seemed ok, but this
 is the first phone display that I have been impressed with.

I fully agree:

QVGA: the minimum to be useable
HVGA (iPhone): good enough
VGA: impressive

 this is not a my screen is higher dpi than your screen competition. it's
 about making a nice and usable device you want.

 if you ask for vga, but you really can't see the difference between qvga and
 vga, you're not being honest. you're just playing the spec numbers game.

I have good eye sight and I believe many other people do, too. You
don't need very good eye sight to see the difference but I guess you
need it to fully make use of the high resolution.

What do we not need VGA for?
-Videos. The phone won't do VGA videos anyway and resolution isn't
that important when watching videos. (See the popularity of
YouTube...)
-Finger applications. Displaying huge buttons in high resolution is
beautiful but not useful.

What do we need VGA for?
-Ebook reading. I read Cory Doctorow's Someone Comes to Town, Someone
Leaves Town in very tiny font on my Neo. It was a great experience.
But even fonts that are a little bigger still profit a lot from the
high resolution.
-Web browsing. There are a lot of tricks to display web pages at low
resolutions. I haven't seen anything that works well, though. VGA is
the smallest resolution to do web browsing well.
-Other things that use text (word processor, speadsheet, calendar,
...) and stylus applications in general.
-Games. Not necessarily 3D games but things like OTTD. RTS on a
handheld becomes usable at 480*320 and fun at 640*480. Since we don't
have buttons, those are the games that are possible on current Neos.
-Maps. The tiny map portions you can fit into 320*240 aren't really useful...
-Comics. Again, 640*480 is the smalles resolution most comic pages
become readable at.
-Pictures. They can be displayed at QVGA but only at VGA they look
perfect, because it's hard to see the individual pixels. Not being
able to see the individual pixels is pretty much the point of the high
resolution!
-The text console. The terminal app is bad enough with the huge font
it is set to at the moment. Way back it had a very tiny font that
worked great. Can you imagine it at 320*240? I can't.

What future OpenMoko devices need is a bigger screen area. Making the
problem worse by decreasing the resolution to a quarter is not a good
idea. 480*320 is the lowest resolution I could live with but I'd much
rather have 800*480. When I get my Pandora, that's what I'll get used
to.

The difference between the VGA screen of the Neo and the QVGA screens I have
are very clear to me (with the VGA being clearly superior) when kept side by
side. But for most of my activities including reading long emails the QVGA
resolution is enough. So unless we have the processing power to run at least
25 FPS VGA video, I would be happy with a QVGA as there is bound to be a
price and performance improvement.

What app/situation you have in mind when you affirm than nobody can detect a 
the difference at half resolution?
I have in mind a web browser a half resolution means double the scroll bars, I 
have in mind a pdf doc viewer, half resolution means I have to zoom in  more 
the document to be readable, also a let you more useful surface to develop any 
app(more buttons, menu items)

I'm wrong with all that thoughts?

Honestly, if the freerunner did not have VGA screen but QVGA, I would not

buy it !



For me, VGA is a must have feature. As other said, there are plenty of QVGA

devices. I don't want one of them because of the resolution.

I have a Dell Axim X5 and I'm really sad about the QVGA resolution (in

addition of the windows OS :( )



Please, please ... keep the VGA screen !

Re: resolution preferences??

2008-06-06 Thread Raphael Wimmer
Hi Carsten,
I'd argue for a VGA screen for three reasons:

On Fri, 06 Jun 2008 07:39:05 +0200, Carsten Haitzler [EMAIL PROTECTED]  
wrote:

1. Greater flexibility. I can use QVGA apps, I can use VGA apps, and I can  
use apps which are written for a fixed screen size in between.

 but it is a waste to pay for a vga screen when we won't use it.

2. The additional price for the better display is not such a huge problem.  
I don't think that a (marginally?) lower price would mean that many new  
customers. You even might lose potential customers who can't live with  
QVGA. When I get my Freerunner, I probably won't replace it with a newer  
phone soon. As the Freerunner is entirely open-source, it will stay  
compatible with new apps or services for a long time. Thus its life-time  
is probably longer than that of closed phones. The additional price for a  
better display is therefore not such a big issue, I think. With VGA the  
Freerunner has at least one great hardware feature that you won't find in  
every other smart phone. For me this is an important reason for wanting to  
buy one.

 how many people out there can really see the difference? be really
 honest. stop thinking my specs are bigger than your specs.

Me.
3. Having used a Sharp Zaurus for ~5 years I am absolutely convinced of  
VGA resolution (though the Z's screen might be bigger than Freerunner's).  
You can see the difference in UI crispness, when displaying photos, when  
drawing. Due to the higher resolution, anti-aliasing is less important.  
Some of the applications I use most often (e.g. TextMaker (word  
processing), KO/Pi (calendar)) would suffer greatly if you had to scale  
the UI down to QVGA.

So, please keep VGA - and offer smooth, fast switching to QVGA.


Cheers,
Raphael

Well, it's hard to know without having an actual device to look at, but
I'll try

My notebook has a 15 inch 1920x1200 monitor which comes to 147dpi.
The Freerunner is 285dpi, the pixels are very close to half the width/
height of my pixels.

So at first I thought wow, that's tiny.  I don't think I need them *that*
small - and I have better than average eye sight.

Then I resized my browser to 640x480 and found I could read it quite
well, though lots of web pages don't quite fit.
I took a screenshot of the window and displayed it at 50% in the GIMP.
So presumably that is how the image could look on the Freerunner.

If I hold this image at the same distance from my eye that I usually
use a notebook (say 55cm) the text looks like it would be too small
to comfortably read, though the reduction of resolution has made it
blurry and I cannot be sure.
If I hold it at the distance that I would typically read a book, which
is closer to 35cm, the text is still a bit small, but I think I would
be quite happy reading it - except that the low resolution has made
it quite blurry. If it were still 640x480, but the same size I think I
could read it quite happily.

So my conclusion is that for reading textual content, the higher resolution
probably is worth it for me.  I doubt it would be of much value for
photo for videos.  I just tried watching a video at [EMAIL PROTECTED],
and it was quite acceptable for the physical size.

The question then becomes - how often will I be reading pages of text
on my Freerunner.  I really don't know.

However maps are very similar to textual content - sharp contrast and
the potential for lots of information in a small space.

I tried a similar experiment comparing a google-maps image
320x240*147dpi and simulated [EMAIL PROTECTED], and the 320x240 felt
very constrained - not enough information on the display.
The 640x480 felt more comfortable and - I think - would have been
readable if I had the real resolution.

Maybe you could ask again we have all had our Freerunners for
a couple of months.

What was the story with 320x240x25fps video again?  Is it possible
with the available memory bandwidth?

But the  freerunner does have a VGA screen and as per information in Steve's
email mass production is about to start/ has started.

The debate is for the GTA03 device that, I believe, will be sold along with
the freerunner and not as its replacement/ next generation (thats GTA04 -
where I wish for WVGA if not SVGA!)

People who want VGA can buy the Freerunner (GTA02) and who wish to pay less
can get GTA03 with QVGA with faster performance. This is good as it will
provide more choices on the OM phone stack and lead to the creation of a
QVGA gui (along with a VGA gui) that will make it easier for OM to be ported
to a number of existing devices also.

Remember Openmoko is not just about having a cool device to show off to
peers but also about opening up the mobile computing world and more the OM
phone stack is used the better.

 For me, VGA is a must have feature. As other said, there are plenty of QVGA

 devices. I don't want one of them because of the resolution.

 I have a Dell Axim X5 and I'm really sad about the QVGA resolution (in

 addition of the windows OS :( )



 Please, please ... keep the VGA screen !


Yeah, same here.

Besides, OM was really advertising the DPI for a long time back in 2006/2007

 Well, it's hard to know without having an actual device to look at, but
 I'll try

 My notebook has a 15 inch 1920x1200 monitor which comes to 147dpi.
 The Freerunner is 285dpi, the pixels are very close to half the width/
 height of my pixels.

 So at first I thought wow, that's tiny.  I don't think I need them *that*

 Then I resized my browser to 640x480 and found I could read it quite

 I took a screenshot of the window and displayed it at 50% in the GIMP.
 So presumably that is how the image could look on the Freerunner.

No. Now you need to zoom 2x. Then compare the original with this.
They should occupy the same amount of space on your screen, but
the QVGA should only have half the pixels.

 Carsten, 
 What app/situation you have in mind when you affirm than nobody can detect a
 the difference at half resolution? I have in mind a web browser a half
 resolution means double the scroll bars, I have in mind a pdf doc viewer,
 half resolution means I have to zoom in  more the document to be readable,
 also a let you more useful surface to develop any app(more buttons, menu
 items)
 
 I'm wrong with all that thoughts?

yes. :) wrong. :) you assume that you have to render 1:1, rendering a web page
or pdf - you can render to an intermediate buffer than it higher res THEN scale
down to screen res (be it vga, qvga or whatever it is) much like you scale any
image the difference would be how sharp or blurry it is. and the vga screen
will look blurry to anyone without excellent eyesight anyway (or someone
with their eye about 3cm from the screen)... thus my point :)

 But the  freerunner does have a VGA screen and as per information in Steve's

no one ever said the freerunner would have anything but vga. i'm asking in

people think! :)

 The debate is for the GTA03 device that, I believe, will be sold along with

yup! much more like it - maybe not even gta03, maybe gta04/5/6 etc. but i want
to know. convince me vga is incredibly more useful than qvga. convince me you
all have amazing eyesight! :) i am doing this because i am trying to listen to
the community and if given a choice - choose the right way based on what you
guys think, but PLEASE, be practical, and honest. be honest with yourselves.
this is not a my screen is higher dpi than your screen competition. it's
about making a nice and usable device you want.

if you ask for vga, but you really can't see the difference between qvga and
vga, you're not being honest. you're just playing the spec numbers game.

 People who want VGA can buy the Freerunner (GTA02) and who wish to pay less
 can get GTA03 with QVGA with faster performance. This is good as it will

yup. and one day we may have a miniature phone that is the size of a coin and
have a qvga screen on it. we will need to work with it, so a qvga phone at any
time is not a bad idea.

but as i said - i'm just looking to see what people think. and why. i'm very
interested in why. why is a vga screen so important? can you REALLY see all
the pixels? can you REALLY read an 8-point font on that screen at that size?
(be honest!). from what i notice of people such a font is just a blurry mess to
them and they are always increasing font sizes to be able to read anything,
thus why spend so many pixels on it? but if you really can see that well - it
does make sense. at least if u are always looking at static content. i content
moves/animates, it's useless again.

so yes - the blurry scaled down in gimp @ qvga would be a qvga screen on a

No again :). Someone has mentioned this before, but I thought I'd clear 
this up since it's come up a few times. QVGA stands for Quarter VGA 
(320*240 = 75kpix), so it's 1/4 of the pixels of real VGA (640*480 = 
300kpix). Half the height and you have half the pixels, after that half 
the width and 1/4 remains.

Having an edge in the my spec is bigger than yours-world wide
championship is indeed good for marketing. Which sells more phones and
spreads the open concept.

Personally, i'd like VGA with the option to switch to QVGA for
power-saving. (You DID save power on QVGA, no?).

But then, I live in the west and the difference in price isn't a
showstopper for me.

Re: resolution preferences??

2008-06-06 Thread Scott Petersen

 i'm asking the question if going down to a (relatively) low resolution screen
 would be an ok compromise.
   
I would not be remotely as interested in a device which is not, at 
least, VGA. As another person mentioned qvga is too small to do any type 
of web browsing effectively. I currently use a Palm TX as my PDA and 
find that the 320 x 480 screen still does not have the resolution to 
make the browsing experience anything but painful.

Cheers

Re: resolution preferences??

2008-06-06 Thread Dale Schumacher
When printer technology went from dot-matrix to laser-print (and later,
ink-jet) there was a substantial qualitative difference in the visual
appearance and quality of the output.  One of the most attractive features
of the Neo, for me, is the corresponding jump in display resolution.  I've
been waiting for this ever since laser-printing arrived!

BTW, I would be perfectly happy driving VIDEO at lower resolution, but
graphics, and especially text, really benefits from resolutions nearing the
300dpi range.

 Subject: Re: resolution preferences??
 The difference between the VGA screen of the Neo and the QVGA screens I
 have are very clear to me (with the VGA being clearly superior) when kept
 side by side. But for most of my activities including reading long emails
 the QVGA resolution is enough. So unless we have the processing power to run
 at least 25 FPS VGA video, I would be happy with a QVGA as there is bound to
 be a price and performance improvement.

  If it is acceptable to use QVGA, couldn't that basically be done without
 any
  hardware changes?  I believe I remember you saying the glamo does
 scaling,
  so couldn't you let SW treat the display as qvga, and just have the
 glamo
  scale it up?
 
  Or, is the question more about having qvga instead of the glamo (which
  leaves you back with the SDIO interface shortage)?

 we can just drive the vga screen at qvga. no need for scaling - just
 change the
 output at the lcd controller level. but it is a waste to pay for a vga
 screen
 when we won't use it. also it does look blocky. it isn't about glamo or
 not -
 it's separate to glamo entirely. simply - how important is a vga screen...
 really? how many people out there can really see the difference? be really
 honest. stop thinking my specs are bigger than your specs. scan u REALLY
 see
 all the pixels on a vga screen of that size. i bet to most people its all
 a
 blur - a qvga screen looks identical to them. only to a minority who have
 very
 good eyesight does it really make a difference, but this is just my bet.
 i'm
 asking the question - and hoping for real honest answers.

 quick question - would you prefer a qvga lcd (save a bit of cost)
 since
   we'e
 going to need to software-drive all graphics - the fewer pixels
 you
   have to
 fill, the better for speed. i'm really tossing up if the speed of
 qvga
   is
 worth the loss of resolution. i'm just not sure.

 Would that be 320x240 (QVGA [1]) or 480x320?

qvga is 320x240. wqvga... that's a whole world of resolutions (400x240,
432x240, 480x272, 480x320). :)

 I think the latter would be acceptable in terms of usability.
 OTOH it would also

but it's not a drop-in replacement as its widescreen. we c ould go for 2.8 vga
or 2.8 qvga. drop-in replacement. anything else mans new case/design etc. etc.

also remember just getting supply of a screen is hard. you also need it at a
decent physical size.
