View Full Version : Time display

I have a couple comments about the time display on the Jive remote.
The tiny time display in the lower right corner of some screens does not agree with the system time. When I use the any of the clock screen savers, they shows the correct system time.
About a week ago, the block clock went from displaying smooth yet blocky characters to displaying characters made from little square blocks. I prefer the old font without the gaps between the blocks.

This will be fixed in an upcoming release. Richard's working hard on
merging in an updated kernel which will fix the real time clock and
give a big boost in performance. Probably a bit more than a week
before it hits the nightly builds.

Any chance we could get Richard's change log for the kernel update? It's not really important, just general curiosity because I'm playing with some jive kernel stuff now.

Well it's a completely new kernel (2.6.22) and a new toolchain. See http://svn.slimdevices.com/branches/linux-2.6.22/?root=Jive for the checkins.
Out of interest what are you doing?

So far, I've really done nothing. I've only had the remote since Monday so I'm just familiarizing myself with what modules and features have been compiled in, the boot process, etc.. I've never used an accelerometer before so I've been peeking at that in hopes of adding a few possibly useful features. I have hundreds of ideas of what I would like to do, but we'll see how many of them come to fruition.

I suddenly got a vision of someone using the Jive remote like a WII. LOL. Sorry for the OT post.

.., I've never used an accelerometer before so I've been peeking at that in hopes of adding a few possibly useful features.
I was thinking of some of those myself, including doing a playlist shuffle by shaking the thing (well why not?) and a ball-bearing-in-a-maze type of game. I've got as far as displaying raw accelerometer numbers in an applet, but I'm having a hard time relating these to actual motions.
I'm also at some point going to port the Lyrics.pm plugin to Lua, using the wheel to navigate the Lyrics, or maybe automatic scrolling (at last!).

I was thinking about this stuff too. This was one of the better links I found (can follow a couple others on from there) about the math of determining pitch, roll, yaw, and then on towards more complex gesture stuff, from Wii accels:

I was thinking of using gestures to control more rapid scrolling.
If a user could press and hold the middle "select" button, while tilting the remote forward or backward, you could scroll very quickly based on the how much you tilt the remote. It's not going to be precise, but it might faciliate flying through long lists or jumping whole letters in the alphabet.
Eh... It's an idea. Whether I can get it scroll fast enough or precise enough, is another matter.
By holding down the middle button, you enable the accelerometer for lists (I just need to check that holding the middle button doesn't already do something.)

Please do! That's a killer idea, especially as I use shuffle a lot ;-).
Some other interesting motions I was thinking would be useful:
1. clockwise rotation is Next Track
2. counter-clockwise is Previous Track
3. quick down-up pulls up the volume bar, and left/right lowers/increases volume
4. wave it around like a magic wand is random playlist

My idea for today: If it's sitting on the desk, turn it over to
pause the audio.

Oooooooooohhh...... That's a good one.
Rather than hardcoding the response to given movements,
Why not come up with a library of gestures, or
create / raise gesture events, and then just map the gesture events to actions.
In this way you can have a default set of gesture->action mappings,
but people can customize the mapping(s) to their tastes ...

I think that this is a good idea. A single Jive applet that watches
the accelerometer and then issues events based on gestures, which are
described by data (which might just be Lua files).

Grahame, you make a good point. I think a library of known gestures is the only way to do this. I spent the past hour trying to get a script to recognize right-flipping the remote on its side. Getting the threshold and "fuzz" factors right has just been trial and error and I have YET to get it to work properly (I estimate a 55%-60% success rate at the moment...). Tweaking these numbers will take some time and having a predetermined library of recognized motions would benefit everyone.

the motion events are currently rather wonky. z works, but x and y
can jump around wildly.
part of the problem is that the values are being averaged, and some
inputs are negative, causing the signed raw value to
map incorrectly to the unsigned motion vector values.

Yes, I've been having trouble with X-axis as well, which I rely on for sensing a right-hand flip. Often times, X doesn't even show as having changed unless I give it a gentle tap, thereby shaking all the sensors.

Ahhhh, That's why I can't get values to read above +-55. I'm going to have to dig a lot deeper if I'm going to get anything to work with this sensor. Thanks!

I've been hacking away at the code in bits lastl week, the lack of
response makes it very difficult when repeated motions are nearly
impossible to exactly replicate without a robot builder on staff.
Averaging doesn't work for simple motions because of course, each
motion starts with a positive acceleration, but ends with a negative
acceleration (unless you are REALLY dedicated to keeping it in
motion). However, hacking to draw out purely raw events is giving me
very different values for seemingly similar motions. This week has
been basically a write off as far as any testing.

Imagine giving Pandora a thumbs down: shake the remote _hard_.

I'm also at some point going to port the Lyrics.pm plugin to Lua, using the wheel to navigate the Lyrics, or maybe automatic scrolling (at last!).
also note that you may be able to drive a lot of this from SC to Jive, without doing any Lua...see my post on Random Mix

I think for lyrics, it would make sense to have it available directly from a songinfo page, so the existing support for pushing SC plugin content to Jive isn't quite there, but I still see the majority of the heavy lifting still being done by your SC plugin.
Let me know when you want to roll up your sleeves on this one, and I may be able to get you a hand. Lyrics, Album Reviews, and Artist Biographies are three things I'm seeing as pretty killer extensions on the Jive platform.

It maybe a while yet. My day job is keeping me from the fun stuff.
