## Datenverständnis

|
|
|
|
|
2023-08-18 13:42:18 +02:00
|
|
|
|
* Welche Einheit haben x und y? Pixel? --> yes
|
|
|
|
|
* Welche Einheit hat scale? --> some kind if bit, does not matter, when
|
|
|
|
|
calculating a ratio
|
|
|
|
|
* rotation wirklich degree? --> yes
|
2023-08-14 16:57:03 +02:00
|
|
|
|
* Nach welchem Zeitintervall resettet sich der Tisch wieder in die
|
2023-08-18 13:42:18 +02:00
|
|
|
|
Ausgangskonfiguration? --> PM needs to look it up

## Tisch-Software
|
|
|
|
|
|
|
|
|
|
* Gibt es Doku für die Bilder, die über die xml files hinausgeht? Sowas wie
|
|
|
|
|
ein Manual oder ähnliches?
|
|
|
|
|
* Gibt es evtl. irgendwo noch ein Tablet mit der Anwendung drauf?

## Event Logs
|
|
|
|
|
|
|
|
|
|
* Wie gehen wir mit "nicht geschlossenen" Events um? Einfach rauslöschen?
|
|
|
|
|
- für Transform tendiere ich zu ja, weil sonst total uninteressant
|
|
|
|
|
- bei flipCard bin ich nicht so sicher... Aber man kann dann keine
|
|
|
|
|
duration berechnen, wäre NA
|
|
|
|
|
* Moves/scales/rotations ohne Veränderung würde ich auf jeden Fall
|
|
|
|
|
rauslöschen
|
|
|
|
|
* Es ist nicht möglich (bzw. ich weiß nicht wie) zusammengehörige Events
|
|
|
|
|
eineindeutig zu identifizieren
|
|
|
|
|
- nach Heuristik vorgehen? Doppelte Transformation start und stop einfach
|
|
|
|
|
raus?
|
|
|
|
|
- Daten sind nicht "fehlerfrei"; es gibt z.B. Transformation-Events wo
|
|
|
|
|
das Ende nicht geloggt wurde
|
|
|
|
|
* Wie identifiziere ich eine "Interaktionseinheit"?
|
|
|
|
|
- Was ist ein "case"?
|
|
|
|
|
- Eher grob über Zeitintervalle?
|
|
|
|
|
- Noch irgendeine andere Idee?
|
|
|
|
|
* Herausfinden, ob mehr als eine Person am Tisch steht?
|
|
|
|
|
- Sliding window, in der Anzahl von Artworks gezählt wird? Oder wie weit
|
|
|
|
|
angefasste Artworks voneinander entfernt sind?
|
|
|
|
|
- Man kann sowas schon "sehen" in den Logs - aber wie kann ich es
|
|
|
|
|
automatisiert rausziehen? Was ist meine Definition von
|
|
|
|
|
"Interaktionsboost"?
|
|
|
|
|
- Egal wie wir es machen, geht es auf den "Event-Log-Daten"?
|
|
|
|
|
* Anreicherung der Log-Daten mit weiteren Metadaten? Was wäre interessant?
|
|
|
|
|
- Metadata on artworks like, name, artist, type of artwork, epoch, etc.
|
|
|
|
|
- School vacations and holidays
|
|
|
|
|
- Special exhibits at the museum
|
|
|
|
|
- Number of visitors per day
|
|
|
|
|
- Age structure of visitors per day?
|
|
|
|
|
- ... ????

# Problems and how I handled them
|
|
|
|
|
|
|
|
|
|
This lists some problems with the log data that required decisions. These
|
|
|
|
|
decisions influence the outcome and maybe even the data quality. Hence, I
|
|
|
|
|
tried to document how I handled these problems and explain the decisions I
|
|
|
|
|
made.

## Weird behavior of `time_ms` and neg. `duration`values
|
|
|
|
|
|
2023-08-18 13:42:18 +02:00
|
|
|
|
I think the negative duration values happen, when an event starts in one
|
|
|
|
|
log file and completes in another one. The variable `time_ms` seems to be
|
|
|
|
|
continuous within one log file but not over several log files.
|
|
|
|
|
|
|
|
|
|
```{r}
|
|
|
|
|
dat_all[which(dat_all$duration < 0), ][1:5, 1:10]
|
|
|
|
|
|

# trace 2052

|
|
dat4[dat4$trace == 2052,]
|
|
|
|
|
|
|
|
|
|
dat[dat$fileid == "2016_11_17-14_12_10.log" & dat$date == "2016-12-17 14:21:51", ]
|
|
|
|
|
dat[dat$fileid == "2016_11_17-14_22_10.log" & dat$date == "2016-12-17 14:22:25", ]
|
|
|
|
|
|
|
|
|
|
tmp <- dat[23801:23950, ]
|
|
|
|
|
tmp[tmp$artwork == "502", ]
|
|
|
|
|
|
|
|
|
|
plot(time_ms ~ as.factor(fileid), dat[1:5000,])
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
The boxplot shows that we have a continuous range of values within one log
|
|
|
|
|
file but that `time_ms` does not increase over log files.
|
|
|
|
|
<!--
|
|
|
|
|
TODO: I will probably update how events are closed and the names of these
|
|
|
|
|
data frame, especially `dat3` and `dat4` will have to be adjusted.
|
|
|
|
|
-->
|
|
|
|
|
Since it seems not possible to fix this in a consistent way, I will set
|
|
|
|
|
negative durations to `NA`. I will keep `time_ms.start` and `time_ms.stop`
|
|
|
|
|
in the data frame, so it is clear why there are no durations. Maybe it
|
|
|
|
|
would also be useful to keep `logfileid.start` and `logfileid.stop` in the
|
|
|
|
|
data? Maybe just for proof checking this theory...
|
|
|
|
|
|
|
|
|
|
Part of it was that timestamps that are part of the log file names are not
|
|
|
|
|
zero-left-padded. But this fixed only three `move` events, since it only
|
|
|
|
|
fixed irregularities *within* one log file.
