is the TapSec needed?
The Pen environment imposes unique demands upon the
user for visual attention, mental processing and manual skill. As a result a precise standard is required to adequately gauge the advantages of acceleration
technologies in Pen-Centric environments.
The TapSec was developed by Synaptek to
provide a way of comparing the relative performance of acceleration
technologies and their impact on the end user.
What is the TapSec?
The TapSec measures the performance of an
input method relative to theoretically perfect
acceleration. It is a complexity-attention measure designed to gauge the
efficacy of input technologies.
the more complex a task in terms of visual and mental processing the
longer it will take to perform. Likewise the more Taps or selections
required the more attention and effort that is required.
TapSec is calculated by using the time taken to enter a character
sequence (complexity) and the number of Taps or selections required
(attention or effort).
How does it work?
For any given test sample an experienced
operator enters the sample employing the features of the acceleration
technology under test to the best of its potential.
Tap counts (coordinated selections) and
times are recorded for each character sequence ending in a
Multiple test passes are performed under
identical test conditions and the minimum values are taken for each character sequence
to eliminate operator variance.
The complexity-attention measure for each character
sequence is obtained by multiplying the Taps by the Time required
for the sequence.
These results are averaged over the
sample and presented as a percentage of what could be achieved with a perfect
acceleration technology for the same sample.
acceleration in the context of the TapSec is defined as follows:
coordinated selection* for any one-character sequence ending with
coordinated selections for any two-or-more character sequence
ending in a space.
Punctuation, Special characters and numbers are not counted.
(they are assumed as part of the sequence.)
user is estimated to maintain an average of N coordinated
selections per second over the sample space. The value N is
based on the mechanical requirements of the environment under
test. In general N is the average time in milliseconds for
the user to move the stylus (Pen or finger etc.) to any given point on
the environment under test and subsequently make a selection.
A coordinated selection is defined as any hand motion to a specific
point on the input environment requiring the visual attention of the
operator and subsequent selection.
In general most input methods adapt to the
user input in some fashion or other. Therefore it is important when
employing the TapSec that all systems are tested under equivalent
There are two acceptable modes of
Out Of The Box (OTB)- In this mode
systems are run through the test sample immediately subsequent to
installation with no modifications to there system defaults.
Fully Adapted - In this mode systems are
run through the identical test sample immediately subsequent to the OTB
