Usability evaluation for input operation using frequency analysis of oculo-motors
Minoru Nakayama, Makoto Katsukura (Tokyo Tech) MBE2007-121
Abstract (in Japanese) (See Japanese page) 
(in English) The aim of this report is to examine the feasibility of assessing usability
using the frequency spectrum of oclulo-motors up to 4 $Hz$.
An input operational task experiment was conducted
using a mouse (Mouse), a keyboard (KeyBD) and a keypad (KeyPAD),
and the traditional subjective system usability measurements (SU-scores)
and error rates were measured.
The order of SU-scores from high to low was Mouse, KeyBD and KeyPAD.
Most power spectrum densities (PSD) for oculo-motors in the first second
of the experiment followed the same order of the SU-scores or error rates.
Cross spectrum densities (CSD) between horizontal and vertical eye-movements
also reflected the results of the SU-scores and error rates.
According to the relationship
between frequency spectrum and SU-scores or error rates,
SU-scores significantly correlate with CSDs
in the frequency range 1.5 -- 2.5 $Hz$,
and error rates correlate with CSDs in all frequency ranges
except 3.0 -- 3.5 $Hz$.
