Sensor Signal Data Set for Exploring Context Recognition of Mobile DevicesKeywords: context data, context-awareness, mobile-awarenessTerms of usageThe data set and the associated images can be freely used for research under the following conditions:
Contact address(where firstname=johan and familyname=himberg). Description of the dataDescription of data and studies where the data has been usedSee the article. You can find some of the further references listed in the paper here.There are five scenarios numbered 1-5 each containing 40-50 repetitions. The scenarios are scripts that describe what the testees had to do (mainly walking inside/outside, using elevator or stairs, sitting by desk or sitting in a coffee room). Each scenario was repeated then 40-50 times by two testees. Unfortunately, there is no labeling telling which of the testees made each repetition. Summary on user activites in each scenario Data formatThe data is in ASCII file contextdata.txt. The columns are separated by tabulators. The columns are as follows
Images (video captures)You'll find here also sequences of images that are snapshots of a video recording on a repetition from each scenario. This hopefully helps in seeing what the testees did during each scenario. Filename scenXX-YY_ZZZ.jpg means scenario XX, repetition YY, ZZZ seconds from the beginning of that repetition. You'll notice that the time stamp ZZZ is not very well in sync with the actual recording of the context data.DownloadData (zipped)Images from scenarios 1-2 (zipped) Images from scenarios 3-5 (zipped) ![]() http://www.cis.hut.fi/jhimberg/contextdata/index.shtml webmaster@www.cis.hut.fi Wednesday, 12-May-2004 10:50:05 EEST |
