\label{app:keyswitch}
|

\newpage
|
||||
To gather information about available actuation forces, the product lines of
|
||||
keyswitches for all well known manufacturers, namely Cherry, Kailh, Gateron,
|
||||
Matias, Razer and Logitech were collected. Since some of the key actuation
|
||||
forces listed on the manufacturers or resellers websites were given in \gls{cN}
|
||||
and most of them in \gls{g} or \gls{gf}, the values were adjusted to gram to
|
||||
reflect a trend that is within a margin of ± 2 g of accuracy. The results shown
|
||||
in \textit{Figure \ref{fig:iter}} are used to determine the minimum, maximum and most common
|
||||
actuation force for broadly available keyswitches.

{\huge Impact of personalized, per key, actuation force on efficiency, effectiveness and ergonomics while using mechanical keyboards}
|
||||
{\huge Impact of adjusted, per key, actuation force on efficiency and satisfaction while using mechanical keyboards}
|
||||
\subsection{Motivation}
|
||||
In recent years, computers are used to some extend in almost every industry in
|
||||
Europe \cite{eurostat_ent_w_comp} and China \cite{iresearch_ent_w_comp}. This
|
||||
leads to the conclusion, that also other countries must have a high usage of
|
||||
computers in corporations. Furthermore, according to a statistic published by
|
||||
\citeauthor{itu_hh_w_comp} in 2019, nearly half of the worldwide households have
|
||||
access to at least one computer \cite{itu_hh_w_comp}. One of the most used
|
||||
devices for data input while operating a computer is the keyboard
|
||||
\parencite[22]{handbook_chi}. Therefore, people who use a computer, either at
|
||||
home or to fulfill certain tasks at work, are also likely to use a keyboard. An
|
||||
important part of a keyboard is the keyswitch also called keyboard key or
|
||||
key. Those keyswitches use, depending on the manufacturer or keyboard type,
|
||||
different mechanisms to actuate a keypress. More commonly used mechanism to date
|
||||
are scissor switches, mostly used in laptop keyboards, dome/membrane switches,
|
||||
often used in low- to mid-priced keyboards, and mechanical switches which are
|
||||
the main switch type for high-priced and gaming keyboards
|
||||
\cite{ergopedia_keyswitch}. Depending on the mechanism and type of key used, it
|
||||
is possible that different force has to be applied to the key to activate
|
||||
it. Normally, the force required to activate a key is identical for each key
|
||||
across the keyboard. However, previous research has shown, that there is a
|
||||
disparity in force generated by different fingers
|
||||
\cite{bretz_finger_force}. This raises the question, why there are no keyboards
|
||||
with adjusted actuation forces per finger or even customizable keyboards, where
|
||||
an individual can select the actuation force for each keyswitch individually.
|
||||
|
||||

\subsection{Methods}
|
||||
% This thesis is intended to provide an overview of already conducted research in
|
||||
% the domain of keyboards, especially in connection with actuation force and the
|
||||
% impact of different keyswitches on keyboard users.
|
||||
|
||||
% Because there is no previous research in the particular field of per finger/key
|
||||
% actuation force for (mechanical) keyboards and the impact of such customization
|
||||
% on efficiency and comfort, this thesis is also intended to research if this is a
|
||||
% viable option in comparison to the classic keyboard with uniform actuation
|
||||
% force. Therefore the author proposes to answer the question:
|
||||
|
||||
This thesis is intended to research if a keyboard with zones of keys, which have
|
||||
adjusted actuation force depending on the assigned finger for that zone and the
|
||||
position on the keyboard, is a viable option compared to the standard keyboard
|
||||
with uniform actuation force across all keyswitches.

\section{Proposed Method}
|
||||
|
||||
\subsection{Subjects}
|
||||
|
||||
Main target group to recruit participants for the research study from are
|
||||
personal contacts and fellow students. It is planned to recruit ~20 participants
|
||||
in total. Participants are required to type with more than just one finger per
|
||||
hand. Thus, touch typing is not a mandatory but helpful skill to
|
||||
participate. The age distribution for the subjects is estimated to be between 18
|
||||
and 56 years. The average typing speed should be known prior to the main
|
||||
experiment. Therefore, a typing speed test should be performed on the subject's
|
||||
own keyboard beforehand. This pre experiment typing test has to be performed
|
||||
within the standardized test environment consisting of an adjustable chair,
|
||||
desk, monitor and the typing test software used within the main experiment.
|
||||
Also, all subjects have to give their written consent to participate in the
|
||||
study.
|
||||
|
||||
\subsection{Study design}
|
||||
|
||||
The experiment should consist of a experimental group and a control group. The
|
||||
control group will perform all typing tests with the same keyboard. The text
|
||||
used for the typing test should be easily understandable. Therefore, the text
|
||||
has to be evaluated with the help of a Flesch-Kincaid scala \cite{flesch_fre}
|
||||
adjusted for German language \cite{amstad_fre}.
|
||||
|
||||
\begin{equation}\label{fre_german}
|
||||
FRE_{deutsch} = 180 - \underbrace{ASL}_{\mathclap{\text{Average Sentence Length}}} - (58,5 * \overbrace{ASW}^{\mathclap{\text{Average Syllables per Word}}})
|
||||
\end{equation}
|
||||
|
||||
The adjusted formula (\ref{fre_german}) to estimate the understandability of the
|
||||
texts used in this experiment usually yields a number in the range of
|
||||
\([0;100]\) called the \gls{FRE}. Higher \gls{FRE}s refer to better
|
||||
understandability and thus the texts used in this experiment all have to fulfill
|
||||
the requirement of a \gls{FRE} \(> 60\) which represents a standard text
|
||||
\cite{amstad_fre} and \cite{flesch_fre}.
|
||||
|
||||
One typing test will consist of several smaller, randomly chosen, texts
|
||||
snippets. The length of the snippets has to be between 100 and 400 characters
|
||||
and a snippet has meet the \gls{FRE} requirement. The snippets are generated by
|
||||
volunteers via the web interface of the platform used in this experiment which
|
||||
can be seen in Figure \ref{gott:contribute_text}.
|
||||
|
||||

\label{gott:contribute_text}
|

\end{figure}
|
||||
|
||||
|
||||
% ASK: Should there be a control group at all, if so should they use their own keyboard or always the same random keyboard while they think they are testing different keyswitches?
|
||||
|
||||
\textbf{Planned experiment procedure:}
|
||||
|
||||
\begin{enumerate}
|
||||
\item Pre-Test questionnaire to gather demographic and other relevant
|
||||
information e.g., touch typist, average \gls{KB} usage per day and previous
|
||||
medical conditions affecting the result of the study \gls{RSI}, \gls{CTS},
|
||||
etc. (5 min)
|
||||
|
||||
% ASK: Medical conditions OK?
|
||||
|
||||
\item Adjustment of test environment (Chair height, monitor height, etc.) (2 min)
|
||||
\item Familiarization with the typing test (5 min)
|
||||
\item Familiarization with the keyboard (5 min)
|
||||
\item \textbf{Main-Test part 1 (H1-H3):} In this part the subject has to take
|
||||
two, 5 minute, typing tests per keyboard, with a total of 3 keyboards
|
||||
(\gls{KB} A, \gls{KB} B, \gls{KB} C). After each typing test, the subject has
|
||||
to fill out the post typing test keyboard comfort questionnaire. Each keyboard
|
||||
is equipped with one set of keyswitches and therefore provides one of the
|
||||
following, uniform, actuation forces across the whole keyboard: 35 \gls{g}, 50
|
||||
\gls{g} or 80 \gls{g}. These specific values are the results of a self
|
||||
conducted comparison between the product lines of most major keyswitch
|
||||
manufacturers. The results shown in appendix \ref{app:keyswitch} yield, that
|
||||
the lowest broadly available force for keyswitches is 35 \gls{g}, the highest
|
||||
broadly available force is 80 \gls{g}, and the most common offered force is 50
|
||||
\gls{g}. The keyboards used in this experiment are visually identical, ISO/IEC
|
||||
9995-1 conform \cite{iso9995-1} and provide a \gls{QWERTZ} layout to match the subjects
|
||||
day-to-day layout and keyboard format. All keyboards are equipped with linear
|
||||
mechanical keyswitches from one manufacturer to minimize differences in haptic
|
||||
and sound while typing. The order for the keyboards and texts for the
|
||||
individual tests is randomized and across subjects counterbalanced to mitigate
|
||||
order effects \cite{statist_counterbalancing}. \textbf{(total: 65 min)}
|
||||
\begin{enumerate}
|
||||
\item First typing test with \gls{KB} A (5 min) \\
|
||||
Follow-up ISO keyboard comfort questionnaire (ISO9241-410) (5 min)
|
||||
\item Second typing test with \gls{KB} A (5 min) \\
|
||||
Follow-up ISO keyboard comfort questionnaire (ISO9241-410) (5 min)
|
||||
\item First typing test with \gls{KB} B (5 min) \\
|
||||

|
||||
\item Second typing test with \gls{KB} B (5 min) \\
|
||||
Follow-up ISO keyboard comfort questionnaire (ISO9241-410) (5 min)
|
||||
\item First typing test with \gls{KB} C (5 min) \\
|
||||
Follow-up ISO keyboard comfort questionnaire (ISO9241-410) (5 min)
|
||||
\item Second typing test with \gls{KB} C (5 min) \\
|
||||
Follow-up ISO keyboard comfort questionnaire (ISO9241-410) (5 min)
|
||||
\end{enumerate}
|
||||
\item \textbf{Main-Test part 2 (H4):} Another typing test to compare the
|
||||
results of keyboards with uniform actuation force to keyboards with adjusted
|
||||
actuation force per finger/key. Typing tests (2x 5 min + 5 min break in
|
||||
between tests) \textbf{(total: (i) 60 min / (ii) 45 min)}
|
||||
\begin{enumerate}
|
||||
\item \textbf{Alternative Methods:}
|
||||
\begin{enumerate}
|
||||
\item \textbf{Personalized keyboard:} Typing sample text on an analog
|
||||
keyboard with high actuation force (150 \gls{g}) (less accurate) or on a
|
||||
normal keyboard which is placed on top of a force plate (more accurate) to
|
||||
measure difference in typing force per finger and key. The subject should
|
||||
be forced to press every relevant key (letters, digits, common special
|
||||
characters) at least 5 times (Measurement: 15 min, Keyboard adjustment: 15
|
||||
min)
|
||||
\item \textbf{Adjusted keyboard:} Keyboard that is equipped with different
|
||||
zones of keyswitches that use appropriate actuation forces according to
|
||||
finger strength differences and key position. (Keyboard adjustment: 15 min)
|
||||
\end{enumerate}
|
||||
\item Familiarization with the keyboard (10 min)
|
||||
\item First typing test on the personalized/adjusted keyboard (5 min) \\
|
||||
Follow-up ISO keyboard comfort questionnaire (ISO9241-410) (5 min)
|
||||
\item Second typing test on the personalized/adjusted keyboard (5 min) \\
|
||||
Follow-up ISO keyboard comfort questionnaire (ISO9241-410) (5 min)
|
||||
\end{enumerate}
|
||||
\end{enumerate}
|
||||
|
||||
All tests could be enhanced with the use of \gls{EMG} measurement and/or additional force measurement (with force plates) during the typing tests.
|
||||
|
||||
This test scenario is inspired by the tests conducted by \cite{kim_typingforces}.
