`Experience
`This Interactive
`approach to one-handed text entry which exploits the skills
`already developed in two-handed
`typing.
`It is called,
`“Half-
`QWERTY,”
`because it uses only half of
`the QWERTY
`keyboard.
`The technique
`can be used on a standard
`QWERTY
`keyboard (using only half of
`the available keys,
`Figure 1), or with a special half keyboard (Figure 2), The
`former provides wide access to the technique.
`The latter
`provides

`
`HOW DOES IT WORK?*
`the keys
`of all
`is comprised
`A Half-QWERTY
`keyboard
`used by one hand to type on a standard QWERTY keyboardl,
`with the keys of
`the other hand unused or absent. Keys of
`the typing hand are typed as before.
`To type characters of
`the missing hand,
`the user simply holds down the space bar
`and performs
`the finger movement
`previously
`done by the
`missing hand (Figure
`1). Thus, using the space bar as a
`modifier,
`a typist can generate the characters of either side
`of a fill-sized
`keyboard, using only one hand.
`
`IT BE USED?
`HOW WILL
`tasks
`is especially useful when performing
`Half-QWERTY
`and
`frequent
`switching
`between keyboard
`which require
`editing,
`for example. Text can be entered with
`mouse—text
`one hand, and items
`selected and manipulated
`with the
`other.
`Since both hands are in “home position”
`for
`their
`respective task, no time is lost
`in moving
`between devices
`[1].
`Furthermore,
`by implementing
`Half-QWERTY
`on a
`standard keyboard, one can ea~sily switch between this type
`of
`input and two-handed
`typing.
`Finally,
`since each side clf
`the keyboard is mapped onto the other side when the space
`bar is depressed,
`the user can choose which hand to use fcr
`one-handed typing.
`In effect,
`the user has a choice of three
`keyboards
`in one: a two-handed QWERTY
`keyboard,
`and
`two Half-QWERTY
`keyboards, one for each hand.
`
`than carried, has significant

`advantages for data collection
`“in the field.”
`By eliminating
`infrequently
`used keys (e.g.,
`the number keys) and reducing
`the size of the space bar, a Ha’lf-QWERTY
`keyboard can be
`made small enough to wear on the wrist of
`the dominant
`hand (Figure 2). With an LCD screen worn on the other
`wrist,
`the resulting
`typing posture allows
`the user to type
`and view the display,
`simultaneously.
