Summary: In this paper, we describe FrontPanel, a tangible user interface that
enhances accessibility features in an iPad. More specifically, FrontPanel was
designed for the senior population who has difficulty interacting with
touch-screen tablets because of the lack of tangibility. FrontPanel is a result
of one year help sessions with elderly who wished to replace their
desktop/laptop computer with a touch-screen tablet that has the advantage of
being light and mobile.

Summary: The lack of tangibility while interacting with virtual objects can be
compensated by adding haptic and/or tactile devices or actuators to enhance the
user experience. In this demonstration, we present two scenarios that consist
of perceiving moving objects on the human body (insects) and feeling physical
sensations of virtual thermal objects.

Summary: In this paper, we discuss the concept of embodied space that led to the
design of InGrid, an Interactive Grid table. InGrid offers several affordances
[1] to the user that could not only interact with tangible and intangible
objects but also with other users.

Summary: A great variety of interactions between senses, and between motor production
and senses, have been reported in previous research. In the present study, we
tested whether the mechanics of a plucked string affected how the sound it
produced was perceived. To test this hypothesis, we simulated the feel of a
plucked string using a high fidelity haptic force-feedback device and
simultaneously simulated its acoustic emission. This way, we could
independently manipulate the two sensory inputs -- how it felt and how it
sounded -- together with physical correct haptic interaction and with accurate
synchronization. This arrangement makes it very plausible that the two sensory
inputs came from a common source. We used a two-interval forced-choice
discrimination procedure to determine the point of subjective equality of the
loudness between a stiff and a soft plucked string. When the stiffness of the
string was low, the sound was perceived to be softer. Interestingly, this
effect was found only when the first string was less stiff than the second
string plucked during a comparison. The results are consistent with the inverse
effectiveness principle of multisensory integration.

Summary: In order to improve the interactivity of mobile interfaces several solutions
have been proposed, including the haptic modality and information
visualisation. For the latter, zooming proves to be a powerful tool to
compensate for the small size of the screen. Thus, in this study, the first
result underlines that the subjects don't have any difficulty to make the
distinction between a zoom-in and a zoom-out when they handle a haptic zoom
through a sensory substitution device. The second result underlines that the
subjects do not handle more than 25 levels and this, even if they have the
possibility of handling more (100 or 1000).

Summary: Studies using the sensory substitution devices reveal that perceptive
activity itself is embodied in a living body capable of movement and possessing
its own spatial dimensions. To study the conditions of a prosthetic perception,
we developed a minimal device, Tactos, which carries out a coupling between the
pen of a graphics tablet and tactile sensory stimulators. This system allows
subjects to explore virtual tactile pictures and is intended to give to blind
people an access to computer graphics. We will present here experimental
results regarding the different aspects of perception using this device.

Summary: In order to design a "haptic zoom", in this fundamental study, we compare
two scaling methods by focusing on the strategies adopted by subjects who are
using a sensory substitution device. Method 1 consists of a reduction of the
sensor size and of its displacement speed. Speed reduction is obtained by a
"human" movement adjustment (hand speed reduction). Method 2 consists of a
straightforward increase in the dimensions of the image. The experimental
device used couples a pen on a graphics tablet with tactile sensory
stimulators. These are activated when the sensor impinges on the outline of the
figure on the computer screen. This virtual sensor (a square matrix composed of
16 elementary fields) moves when the pen, guided by human hand movements, moves
on the graphics tablet. The results show that the recognition rate is closely
dependent on the size of the figure, and that the strategies used by the
subjects are more suitable for method 2 than for method 1. In fact, half of the
subjects found that method 1 inhibited their movements, and the majority of
them did not feel the scaling effect, whereas this was clearly felt in method
2.

Summary: In this fundamental study, we compare two scaling methods by focusing on the
subjects' strategies which are using a sensory substitution device. Method 1
consists in a reduction of the sensor size and its displacement speed. Here,
speed reduction is obtained by a "human" movement reduction (hand speed
reduction). Method 2 consists in a classical increase of the image dimension.
The experimental device couples the pen on a graphics tablet with tactile
sensory stimulators. These latter are activated when the sensor crosses the
figure on the computer screen. This virtual sensor (square matrix composed of
16 elementary fields) is displaced when the pen, guided by a human hand
displacements, moves on the graphics tablet. Even if it seems that there is no
difference between the two methods, the results show that the recognition rate
is closely dependent on the figure size and the strategies used by the subjects
are more suitable for method 2 than the method 1. In fact, half of the subjects
found that method 1 inhibits their movements and the majority of them don't
feel the scaling effect, whereas this is clearly felt in method 2.

Summary: In order to resolve PDA display problems, we validated, in a previous study,
the efficiency of a new zooming technique associated with a tactile feedback
(haptic zoom). The displayed objects on a PDA screen being relatively small, it
appears essential, in the present study, to define minimal and maximal comfort
thresholds to ease gesture execution that correspond to zoom-in and zoom-out
thresholds of the haptic zoom. The results of the experiment undertaken with a
sensory substitution device show that: i) the choice of an object size close to
4 cm significantly increases the recognition rate, ii) minimal and maximal
comfort thresholds, defined by a ratio C (see text), seem to be respectively at
values of C=0.2 and 0.4, iii) strategies used by subjects prove to be
productive if they agree with the requested task (estimate figure size and
orientation) and the explored shape topography.

Summary: The goal of this study is to apprehend the perceptive training capacities of
a human subject via an artificial device and to also underline their limits and
constraints. The principal constraint considered here, is the acuity in other
words, the spatial proprieties ratio of the sensor and the explored objects.
The experimental device couples the pen of a graphics tablet with tactile
sensory stimulators. A matrix of virtual receptor field linked to a stylus by
means of an equipped computer is responsible for the stimulator activation. The
results show: i) that the subjects are able to perceive forms via this
artificial device and that this perception is forced by the spatial resolution
of the sensor, ii) That the subjects are able to adapt their movements to
perceive very small forms (0,5 mm height), iii) To develop new exploration
strategies.
