3 VC questions

Haddood · May 21, 2014, 03:06:08 AM

1. I am looking for a way to measure the time lapsed since last successful recognition and I have no idea where to start ... any ideas appreciated

2. Is there is a way to query VC mode (off, stand by, on) ?

3. When I use scrape.xml, is there is a way to read the inner nodes ? it seems all values comes concatenated

Kalle · May 21, 2014, 07:54:28 AM

1. I think it is possible with a logic block and VC.SetEventTimer, but at the moment I have no idea how.

2. Yes, VC generate a event for each mode like VC.On/VC.Standby and VC.Off, so you can work with this events
As example you can write the current mode on a webserver or send the event to Eventghost ...

3. I think you must use the Scrape.XML action: http://voxcommando.com/mediawiki/index.php?title=Actions#XML

I hope this will help a bit.

1: why ?

2: see Kalle's suggestion. Again, why?

3: Scrape.XML is not very sophisticated. For anything complicated please just use scrape and results.regex.

Just to clarify -- In our "getting support"/"forum rules" documentation, we mention that an important part of posing questions on the forum is to "describe the goal, not the step". (http://voxcommando.com/mediawiki/index.php?title=Getting_support#When_You_Ask)

Knowing the "why" right of the bat tends to save everyone a lot of time, in that there are different strategies one could use to solve a problem depending on the objective.

Without actually knowing why, we're more likely to suggest technically correct answers that are nonetheless unhelpful and potentially frustrating.

Haddood · May 21, 2014, 05:27:03 PM

1. Part of a redundant presence detection ... and conditional responses to make it more humane

2. it has to do with reseting the led lights on serial port to what their state before blinking for low confidence or ignoring recognition ...
3. Rogers ... however scrape.xml much faster (or at least this is how it was in 1.9.5.0 ... will test with the 1.9.5.1) ... it will be great if inner nodes cane be scraped or be assigned matches.x.y

thank you guys for all the responses

3: Scape xml is faster? That is surprising to me. I guess I would need to see what you are scraping, and maybe your command to see how you are doing it. Then I might be able to suggest something.

Maybe this example will help you, maybe not:

for 1 can you explain a bit more.... as far as know no event fired with positive recognition ... if it exist it will be perfect. Record time then subtract ...

for 2 ... I use these events to modify my leds status ... however if I change leds due to low confidence ... there is no way to know which one it was before .. even in the case of a VFD (screen) or arduino, say VFD showing: VC in stand by ... you say something and VFD show low confidence so you know it was not accepted ... how do we know to set screen back to Stand by and not ON

James:

3. The xml file I want to scrape is:
https://montreal.bixi.com/data/bikeStations.xml

I am posting 2 commands, one works with scrape only and one with scrape.xml the first work but takes lots of time to clean the xml ... the second works but data come concatenated ... now the work around I am fetching the data using hard coded {match.x} it is working but the moment they add or remove a station it won't work anymore as I will false results. Ideally I can scrape.xml the node station, with the ID passed as variable ... then sub matches will give the required fields

Again thanks guys for all the feedback

How about something like this?

Code Select

<?xml version="1.0" encoding="utf-16"?>
<!--VoxCommando 1.9.5.1-->
<command id="1158" name="What's the status of {1} station" enabled="true" alwaysOn="False" confirm="False" requiredConfidence="0" loop="False" loopDelay="0" loopMax="0" description="">

    <cmdRepeat>1</cmdRepeat>
  </action>

  <payloadFromXML phraseOnly="False" use2partPhrase="False" phraseConnector="by" Phrase2wildcard="anyone" optional="False">bixi.xml</payloadFromXML>
  <phrase>station</phrase>
</command>

I have a payload xml file with id associated with 'friendly' station name (attached). This executes very quickly.

... There are then various solutions for passing the relevant data to your feedback command.

nime5ter · May 22, 2014, 03:34:50 PM

The following generates a payload xml file with all station names associated with their station IDs.

Code Select

<?xml version="1.0" encoding="utf-16"?>
<!--VoxCommando 1.9.5.1-->
<command id="1161" name="generate bixi xml" enabled="true" alwaysOn="False" confirm="False" requiredConfidence="0" loop="False" loopDelay="0" loopMax="0" description="">

  </action>
  <action>
    <cmdType>Results.RegEx</cmdType>
    <params>
      <param>&lt;id&gt;(.*?)&lt;.*?&lt;name&gt;(.*?)/(.*?)&lt;</param>
    </params>
    <cmdRepeat>1</cmdRepeat>
  </action>
  <action>
    <cmdType>PayloadXML.Clear</cmdType>
    <params>
      <param>bixi.xml</param>
    </params>
    <cmdRepeat>1</cmdRepeat>
  </action>
  <action>
    <cmdType>PayloadXML.AddPair</cmdType>
    <params>
      <param>bixi.xml</param>
      <param>{Match.{i}.1}</param>
      <param>{Match.{i}.2} and {Match.{i}.3}</param>
      <param>True</param>
    </params>
    <cmdRepeat>{#M}</cmdRepeat>
  </action>
  <phrase>generate bixi xml</phrase>
</command>

I've replaced the slash (/) that they use in their station names with the word "and", to improve VC's recognition of each intersection.

You have access to the last mode via the events. Now all you need to do is store the value in a variable. Then you can use the variable later on, in whatever commands. I don't know if you are using python or trying to only use VC commands.

1. If you take a look in your tree editor, there is a group named "Vox Commands". In this groups are stored commands like "listen", "don't listen", "vox off" ...
If you click at the plus next to the "don't listen" command, you will see the phrases for the command, followed by an event "VC.Standby" and the same for the commands "Listen" and "Vox-Off". So far I know this commands are generate events as standard in each VC configuration. If you change the VC mode, you will see a event in you history windows (see attached picture).
In the commands itself you can insert a action which send data over UDP,TCP or whatever you want to a other programm like Eventghost or to your home automation which switch a LED in different colours.

I only tried to provide some assistance for ways to handle the regex question. I leave the rest to you and your compadres. Teamwork!

Haddood · May 23, 2014, 03:54:17 AM

nime5ter,

I think we should call you RegEx Queen ... very neat solution and exactly what I was looking for ... this morning started to experiment with scrape and RegEx but I am still a toddler when it comes to that.

James,
Interesting ... for some unknown reason I am reluctant to use variables, maybe that goes back to my Sinclair PC, where every bytes counts

....

Kalle,
thanks for the explanation however I think I wasn't clearin explaining the issue. my thing was not controlling the leds this is done using VC and a small driver for com port. it was more to fix the led color to VC state after I change it due to low confidence or rejection

a million thanks again guys... you make VC experience lots of fun...
