HRTF funcionts measurements with
three volunteers were made. More information here.
20/11/2002 We are
making measurements to determine which of the three earpieces which we have
is more appropiate to implement in the portable prototype. We tried to find
out which is the one that offers to us a better externalization, using for
the tests the dummy. The obtained results will be displayed as a graph and
they will be compared with another similar experiment, in this case a perceptual
experiment, in wich we will made the measurements with control individuals.
The 3 earpieces are opened,
and of the intraaural, supraaural and circumaural type respectively. In this
experiment we are placing them obstructing the auditory channel with the own
In principle the supraaurals
earpieces seems to be the more appropiated ones, in an aesthetic and functionally
point of view, but it will be necessary to wait for the final result of the
November 2002 The
tests of the new prototype of the cameras unit were made successfully. In
this new prototype, made by Jose Vicente Gigante and Agustín Casanova,
all the microcameras control electronics has been integrated in a circuit
of adapted size to be mounted in the glasses, also simplifying the wiring
of it towards the processor unit. It will represent a base for the construction
of still more reduced new electronics, so that it can be integrated in a model
of small glasses but for infantile use.

Institute of the Canary Islands. More information here.
tests with Candelaria Darias were made, using the new portable prototype in
construction. The objective was to verify the correct operation of the software
and the unit. The correct externalization of the sounds and the capacity of
the volunteer to locate objects in azimuth, height and depth with this new
prototype and different earpieces was verified. More information here.
This year began with
the attendance of members of our equipment to important meetings. On the one
hand, Antonio Rodriguez moved to Madrid to attend the first meeting of the
work group editor of the document "Passed, present and future of the
new technologies for the blind people and people with deficient vision"
that took place on 14 of January at the ONCES's General Council. On the other
hand, Enrique Burunat and Ramon Muñiz attended to the "Third International
Course MR, AMR and Cardio MR" organized by the Radiodiagnostic Service
Universitary Hospital La Fé of Valencia, during days 30 and 31 of January,
and that took place at the Congresses Palace of Valencia.
Also, during this month
we have been continued carrying out perceptuales tests with the new portable

Our project has participated
at the XXXII Congress of the Spanish Society of Physiological Sciences and
International Joint Meeting with the Physiological Society, celebrated att
Puerto de la Cruz, Tenerife, Canary Islands, during 13 to 17 of February of
2003, where they presented and were approved for publication in the official
magazine of the Physiological Society, The Journal of Physiology, two oral
communications titled: "Functional Magnetic Resonance Imaging of Spatial
Auditory Perception in Blind and Sighted Human Subjects", and "Comparative
Study of the Acoustic Response of Human Ears, Head and Torso, and its Sculptural
Reproduction in Silicone, Oriented to the Development of to Sensory Substitution
March 2003 From 17 to 22
of March, some members of our team moved to Los Angeles, USA, to participate
in the 18th Annual International Conference "Technology and Persons with
Disabilities", CSUN 2003. The 17th of March our new portable prototype
was presented in a chat imparted by Antonio Rodriguez. During the following
three days, at the EAV's stand, there were practical demostrations of the
new portable prototipe. More information here.
21 April 2003 The
financing coming from the PROFIT 2003 call was received, by a value of 88000
25 April 2003 Antonio
Rodríguez y Enrique Burunat, with Cynthia Ferraz, moved to participate
in the European Congress of Independent Life, celebrated in the Mare Nostrum
Resort complex at Arona, Tenerife, from the 24 to the 26 of April of 2003.
There they showed the characteristics of the EAV project with a PowerPoint
presentation in the table denominated "Desinstitucionalización",
that was been present at by a great amount of public.
The scientific content
was distributed in Communications, Round Tables and Communications.
This Congress was organized
by the General Secretariat of Social Subjects, Social Institute of Migrations
and Services of the Ministry of Work and Social Subjects and SinProMi.
Also, the Collaborating Organizations were: Government of the Canary Islands,
ONCE, City council of Santa Cruz de Tenerife, Spanish Committee of Disabled
People Representatives, Forum of Independent Life, Disabled Peoples International,
Independence Options Rights empowerment, European Disability Forum, and IASS.
