Matt's Research Log

Line: 2748 to 2748

- - no outline slide
  - CT to send additional images from IMAGER slide deck
  - no captions needed

Changed:

<
<

- analysis of local results; JM sent KM's mixed design + analysis notes

>

- analysis of local results;
  - JM sent KM's mixed design + analysis notes;
  - time positively skewed, score has ceiling effect, negatively skewed (z-scores not appropriate)

- analysis of global results - time positively skewed, score has ceiling effect, negatively skewed (z-scores not appropriate)

- MUX forum - CHI practice talks by MP (Now Where Was I? Physiologically-Triggered Bookmarks), MS (Cardiogram - VA for automotive engineers);

[05.05.11]

Line: 2787 to 2789

Week of [05.16.11]

[05.16.11]

Added:

>
>

- analysis: log-transformed of time data (global and local) (log base 10 tried first, later opted for natural log)

[05.17.11]

Added:

>
>

- analysis: aligned rank transformation of normalized score data (global, local)
  - summarizing results of ART score, log time data for CTOC team meeting;

[05.18.11]

Added:

>
>

- analysis (cont.)
- CTOC team meeting: CL, JM, CT, HL, RH, MB
  - discussion of expt results
  - re-group into 2 age groups at median age (64)
  - to do: plot scatter plots of log time, cost of interruptions, score by age - perform outlier analysis
- generated summaries of results for JM, CT

[05.19.11]

Added:

>
>

- 2 group analysis (2.1,2,5,6,7,12 > young group; 2.3,4,8,9,10,11 > old group)
- n-back analysis / verification

[05.20.11]

Added:

>
>

- questionnaire data entry (216 sheets * 6 responses per sheet = 1296 responses transcribed)
- questionnaire descriptive analysis
  - performance, interruption annoyance levels reflect quantitative results!
- meeting w/ JM
  - 2-group analysis doesn't reveal anything new
  - no surprises from n-back analysis
  - to do: collect quotes from older adults re: interruptions, strategies, which task was perceived as harder;
  - to do: generate key findings for CHI paper
- questionnaire quantitative analysis (parametric analysis); some results highly skewed;

Week of [05.23.11]

Line: 2802 to 2824

- Victoria Day (holiday)

[05.24.11]

Added:

>
>

- non-parametric analysis of survey results using ART technique
- analysis of resumption lag times in SC, SqP (log transformed)
- analysis of RKT vs. IIA (log transformed), between, within tasks
- LUNCH meeting
- Tuesday Tea
- ordering analysis: interruption ordering (NLH); task ordering (SC-SqP); experimenter (MB, CL), location, time-of-day, bank ordering (ABC);

[05.25.11]

Added:

>
>

- questionnaire non-parametric analysis (cont.) - summarized
- meeting w/ JM + CT
  - discussion of quant. results, questionnaire results, RLTs, IIAs,
  - to do: listen to interviews for quotes, perspectives
  - potential explanations of SqP; memory-based task for older adults but not younger adults; Zeigarnik effect for younger and older adults? mind-wandering in younger adults during L-int?
  - CT data analysis ongoing: ATLAS TI qual. data entry
- IMAGER pizza social - TB (really really robust collision detection), RM (context-aware garment modeling)
- MUX meeting - CHI post-mortems #2: fav. talks/papers/trends
  - parallel prototyping
  - design workbooks, collaborative workbooks
  - confessions of a grounded theory PhD
  - usability questionnaires - does it hurt to be positive?
- analysis: RLT vs. IIA cost scatter plots

[05.26.11]

Added:

>
>

- analysis: key points, summarization; to do: send CL summary
