3. TAUCHI MMIG G. Evreinov 01_15 31.10.2003 … Temporal Events a sequential appearance of events, entities, or their properties leads to the time perception [1, 2] in-/decrement of some parameter with time can be transformed into the spatial pattern of discrete or analogous signals spatial distribution of these signals can be proportional, or non- proportional, to the initial temporal intervals – depends on conventions in any case, spatially-distributed signals will be perceived like a sequence of similar or different events which are stimuli for human perception there are two main metaphors for time presentation: Time-line and Clock Face /Dial both “absolute” time imaging and perception have difference /error between real temporal parameters of the event, presented value and perceived moments: onset /start, offset /stop and duration of some interval  Time perception … …

4. TAUCHI MMIG G. Evreinov 02_15 31.10.2003 Temporal Events time is the most important dimension in music its representation and manipulation is crucial for the expressiveness of a composition environment [3] therefore imaging for temporal events was especially developed for Musical Instrument Digital Interface (MIDI) [4]

5. TAUCHI MMIG G. Evreinov 03_15 31.10.2003 Temporal Events Peter Hanappe [3] gives the following list of some of the issues in time representation concerning music events and objects: the description of timing information the construction of composite temporal objects the use of composite objects as basic elements the definition of temporal relations between objects the manipulation and transformation of composite objects the interactive, dynamic control of a composition the relations between continuous time and event time time and hierarchy in musical structures the manipulation of continuous time functions the relation between composed time and performance time the representation of temporal information during runtime the relation between ``out-of-time'' structures and ``in-time'' realization

6. [7] TAUCHI MMIG G. Evreinov 04_1531.10.2003 Temporal Events there are many other examples when user is in time-dependent situation and must evaluate short intervals to make a decision, change own behavior or interaction strategy the systems, based on head /eye /finger tracking, use temporal window to simulate mouse actions herewith, spatial or temporal (sound) time imaging can influence onto the experimental data due to attention & perception features [5, 6, 7] [8]

7. TAUCHI MMIG G. Evreinov 05_15 31.10.2003 Temporal Events [8] [10] “an attention shift can be easily elicited by a stimulus appearing in the periphery (e.g., Theeuwes, 1991) an attention shift takes time (e.g., Müller & Findlay, 1988) a phenomenal representation of a stimulus is not available before the end of an attention shift (e.g., Van der Heijden, 1992)” (cit. on [7])

8. TAUCHI MMIG G. Evreinov 06_15 31.10.2003 Temporal Events http://www.inference.phy.cam.ac.uk/djw30/dasher/movies.html to be an effective, visualization first should concentrate user attention on the task, target or whatever noise is interference of signals with similar parameters that distract and not allow to accomplish the task effectively

10. TAUCHI MMIG G. Evreinov 08_15 31.10.2003 Temporal Events the task is how to synchronize the user behavior regarding temporal window (dwell time, scan interval or whatever) not only to help in visual search, but the time imaging should aid the user in planning the motor actions and with a decision making Usability-testing software for… Time Indicator 1

11. TAUCHI MMIG G. Evreinov 09_15 31.10.2003 Temporal Events the special test showed that visualization of the temporal process sometimes does not add useful information for user but distracts and throws out of time while an average error rate was inessential increased, latent period and dispersion of reactions increased up to 30% ERA DHL GWV Time, ms 600 ERA DHL GWV
