ABSTRACT
Haptic feedback is important to improve the operability of virtual
objects. However, AR systems with haptic feedback are still not
many. Moreover, users cannot perform tasks that need large
workspaces in those systems because of physical constraints from
haptic feedback devices. In this paper, we combined a wearable
haptic device and a marker-less AR technology to develop an AR
system in which users can perform activities that need large
workspaces. Differences of the operability of virtual objects in an
assembly task of large machines are examined to evaluate effects
of the haptic feedback in this system. The result indicates that
haptic feedback is effective and users can perform activities that
need large space in this system.

1 INTRODUCTION
In the research field of augmented reality (AR), not only studies to
superimpose virtual objects but also studies to enable users to
interact with virtual objects have been actively made [1].
Users can interact with virtual objects in AR systems without
haptic feedback. However manipulation of virtual objects is hard
in those systems because users cannot touch them while they can
touch real objects. Studies of virtual reality (VR) indicate that
haptic feedback is important to manipulate virtual objects and the
operability of them gets better by haptic feedback [2].
However, AR systems with haptic feedback are still not many
and users cannot perform tasks that need large workspaces in
those systems because of physical constraints from haptic
feedback devices [3].
We combined a wearable haptic device and a marker-less AR
technology to develop an AR system in which users can perform
activities that need large workspaces. We expect that
manipulation of virtual objects in a wearable AR system gets
easier by haptic feedback and users can perform various activities
because they can move around in such a system.
We examined differences of the operability of virtual objects in
an assembly task of large machines to evaluate effects of the
haptic feedback in this system. We focused on actions of picking,
moving and putting objects in the task and examined installation
errors of them and time that a user needed to pick and put them.
We evaluated the system by the differences of these values in the
task.
