Scenarios for people who are not able to see
1. Maria
The environment is assumed to be totally unknown to Maria.
Being a blind person, Maria has a foldable tactile presentation system. Even if tactile presentations
are in principle available for all users, she prefers to carry her own device so as to avoid potential
problems during her trip.
Original scenario
After a tiring long haul flight Maria passes through the arrivals hall of an airport in a Far Eastern
country. She is travelling light, hand baggage only. When she comes to this particular country she
knows that she can travel much lighter than a decade ago, when she had to carry a collection of
different so-called personal computing devices (laptop PC, mobile phone, electronic organisers and
sometimes beamers and printers). Her computing system for this trip is reduced to one highly
personalised communications device, her ‘P–Com’ that she wears on her wrist.
AmI opportunities
Maria’s P-com can be equipped with specialised interfaces (e.g., a foldable tactile interface). When
necessary, the P-com can communicate with sophisticated peripherals (e.g., a tactile 3-D system)
available in the environment.
Maria calls the P-Com her ‘key of keys’ because it almost invisibly unlocks the doors she meets on
her trip. It allows her to move around in an ambience that is shaped according to her needs and
preferences. In the past travelling involved many different and complicated transactions with all
sorts of different service vendors, often with gaps and incompatibilities between the different
services. In the past few years, a series of multi-service vendors (MSVs) have emerged offering
complete packages of services linked to the P-Com that tailor the user’s environment according to
their preferences. User preferences are set up during an ‘initiation period’ during which personal
agents (personal-servants or perservs) are instructed or learn how to obey their master’s wishes.
These agents are in continual negotiation with those of participating service providers (such as
shops, rental companies, hotels and so on).
AmI opportunities
This new situation, of interest for all people, can be particularly interesting for blind people, who
may presently have problems in accessing complex information services.
A particular feature of this trip is that the country that Maria is visiting has since the previous year
embarked on an ambitious ambient intelligence infrastructure programme. Thus her visa for the trip
was self-arranged and she is able to stroll through immigration without stopping because her P-
Com is dealing with the ID checks as she walks.
312
Appendix I. Scenarios for people
who are not able to see
Problems
Navigating the environment.
Possible solutions
The P-Com in communication with AmI guides Maria through the airport (e.g., by voice, or using
haptic cues).
This requires:
• The knowledge of her position in the airport (granted by AmI);
• The possibility of controlling the presence of unpredictable obstacles (people, baggage, etc.).
The second prerequisite can be addressed through two approaches:
• The first is based on the features of the AmI itself, which could contain a control system able to
monitor tagged objects in real time and communicate with the P-com of passengers;
• The second is based on a personal system (artificial virtual guide dog), that is a set of sensors
(e.g., a worn T.V. camera, or some type of ultrasound or laser) able to spot possible obstacles. RFID
on objects can be used for signalling the presence of obstacles to the virtual guide dog.
AmI opportunities
Navigation in the environment is considered as a problem for a blind person. Instead of creating
new obstacles, AmI has the potentiality of offering a solution to the mobility of blind people in all
environments where its facilities are deployed.
Tracking people and offering context related information is supposed to be one of the standard
features of AmI.
A rented car has been reserved for her and is waiting in an earmarked bay. The car opens as she
approaches. It starts at the press of a button: she doesn’t need a key. She still has to drive the car
but she is supported in her journey downtown to the conference centre-hotel by the traffic guidance
system that had been launched by the city government as part of the ‘AmI-Nation’ initiative two
years earlier.
Problems
Maria cannot drive.
Possible solutions
She uses a taxi.
a) Her P-Com can guide her to the taxi rank or
b) The taxi driver was informed from Maria’s arrival beforehand and he picks her up at the door of
the arrival lounge.
The taxi driver’s and Maria’s P-Coms can communicate so that the driver can locate Maria.
AmI opportunities
See previous point.
313
Appendix I. Scenarios for people
who are not able to see
Downtown traffic has been a legendary nightmare in this city for many years, and draconian steps
were taken to limit access to the city. But Maria has priority access rights into the central cordon
because she has a reservation in the car park of the hotel. Central access however comes at a
premium price, in Maria’s case it is embedded in a deal negotiated between her personal agent and
the transaction agents of the car-rental and hotel chains. Her firm operates centralised billing for
these expenses and uses its purchasing power to gain access at attractive rates. Such preferential
treatment for affluent foreigners was highly contentious at the time of the introduction of the route
pricing system and the government was forced to hypothecate funds from the tolling system to the
public transport infrastructure in return.
In the car Maria’s teenage daughter comes through on the audio system. Amanda has detected
from ‘En Casa’ system at home that her mother is in a place that supports direct voice contact.
However, even with all the route guidance support Maria wants to concentrate on her driving and
says that she will call back from the hotel.
AmI opportunities
Maria has the advantage of being able to speak immediately with her daughter.
Maria is directed to a parking slot in the underground garage of the newly constructed building of
the Smar-tel Chain. She is met in the garage by the porter – the first contact with a real human in
our story so far! He helps her with her luggage to her room.
Her room adopts her ‘personality’ as she enters. The room temperature, default lighting and a range
of video and music choices are displayed on the video wall.
Problems
The traditional remote control is not accessible.
Possible solutions
Maria can use the P-Com. Alternatively, AmI can describe to her the layout and the functionalities
of the remote control.
AmI opportunities
AmI knows itself and its components. If necessary, it is able to describe the layout and the
functionalities of the remote control and of the entire room.
She needs to make some changes to her presentation – a sales pitch that will be used as the basis
for a negotiation later in the day.
Using voice commands she adjusts the light levels and commands a bath.
Problems
Maria cannot do two acoustic activities simultaneously.
Possible solutions
The actions must be sequenced, or an alternative interfaces (Braille) addressing a different modality
may be used.
AmI opportunities
AmI is able to organize sequentially the flow of information and the performance of the necessary
tasks, allocating the necessary time.
314
Appendix I. Scenarios for people
who are not able to see
Then she calls up her daughter on the video wall, while talking she uses a traditional remote control
system to browse through a set of webcast local news bulletins from back home that her daughter
tells her about. They watch them together.
Problems
She can not watch the news, she can listen to the news.
Possible solutions
Listening to the news and communicating with her daughter must be sequenced in some way.
AmI opportunities
The possibility of watching the news together and being able to comment them adds a very
important social dimension to the interaction.
Later on she ‘localises’ her presentation with the help of an agent that is specialised in advising on
local preferences (colour schemes, the use of language). She stores the presentation on the secure
server at headquarters back in Europe. In the hotel’s seminar room where the sales pitch is to take
place, she will be able to call down an encrypted version of the presentation and give it a post
presentation decrypt life of 1.5 minutes.
Problems
Maria cannot see her presentation (neither the colour scheme).
Possible solutions
The agent that advises on preferred colour schemes should be reliable enough to detect and correct
eventual contrast and related problems. Alternatively, a connection with the office is established
through the broadband network, in order to allow a visual inspection of the results.
If Maria had not been born blind and knew colours, she can be informed vocally of the colour
scheme.
AmI opportunities
The additional opportunities offered by AmI are related to the availability of broadband
communication facilities. Maria can be helped by colleagues, who can work cooperatively across
the network. In many situations human support can be more effective and acceptable than
technological support.
The hotel offers neutral third part hosting of presentations but Maria wants to be sure for her own
peace of mind that some of the sensitive material in the presentation will not sit around on a 3rd
party server for prying eyes to see. To do this work, Maria is using hardware provided by the hotel,
but with security clearance and access to her personal home workspace guaranteed by her P-Com.
AmI opportunities
Security is built in the system.
She goes downstairs to make her presentation…this for her is a high stress event. Not only is she
performing alone for the first time, the clients concerned are well known to be tough players. Still,
she doesn’t actually have to close the deal this time. As she enters the meeting she raises
communications access thresholds to block out anything but red-level ‘emergency’ messages.
315
Appendix I. Scenarios for people
who are not able to see
Problems
Maria needs to know who is in the room.
Maria needs to know when she can start her presentation.
Maria needs to control the pace of the presentation.
Possible solutions
The P-Coms communicate and exchange the information on who is attending the meeting.
She gets a multi-modal confirmation (voice through earphone plus vibrator) that the presentation
is ready for display.
There is a tactile display in the room or she can use the personal tactile display. The tactile display
has a copy of the presentation plus additional control functions (active functions), pointing facilities
and slide content details.
AmI opportunities
Probably a normal handshake could be as efficient and more pleasant.
In AmI the wide availability of tactile displays is part of the built in virtual reality interfaces.
The meeting is rough, but she feels it was a success. Coming out of the meeting she lowers the
communication barriers again and picks up a number of amber level communications including one
from her cardio-monitor warning her to take some rest now.
The day has been long and stressing. She needs to chill out with a little meditation and medication.
For Maria the meditation is a concert on the video wall and the medication….a large gin and tonic
from her room’s minibar.
2. Dimitrios
Original scenario
It is four o’clock in the afternoon. Dimitrios, a 32 year-old person working in a food - multinational,
is taking a coffee at his office’s cafeteria, together with his boss and some colleagues. He doesn’t
want to be excessively bothered during this pause. Nevertheless, all the time he is receiving and
dealing with incoming calls and mails.
He is proud of ‘being in communication with mankind’: as are many of his friends and some
colleagues. Dimitrios is wearing, embedded in his clothes, a ‘gateway’ or digital avatar of himself,
familiarly known as ‘Digital Me’ or ‘D-Me’. A D-Me is both a learning device, learning about
Dimitrios from his interactions with his environment, and an acting device offering communication,
processing and decision-making functionality. Dimitrios has partly ‘programmed’ the D-Me himself,
at a very initial stage: it was, he says, a great personal experience to formalise somehow his identity
and the way he envisaged his relations. At the time, he thought he would ‘upgrade’ this initial data
periodically. But he didn’t. He feels quite confident with his D-Me and relies upon its ‘intelligent
PDA-like’ reactions.
AmI opportunities
Even if blind people do not normally have problems in interpersonal communication help in
processing of the complex flow of communications and decision making can be very interesting.
316
Appendix I. Scenarios for people
who are not able to see
Dimitrios has a ‘3P/3CAG D-Me’-it allows him to specify three privacy levels (3P) for personal data
matched to three separate ‘closed access group’ (3CAG) memberships.
AmI opportunities
Privacy is a built in facility of AmI.
At 4:10 p.m. following other calls of secondary importance - answered formally in a smoothly
multilingual reproduction of Dimitrios’ voice and typical accent, a call from his wife is further
analysed by his D-Me. The D-Me confronts available data registered from Dimitrios’ environment
(voices, themes, location, other ‘patched’ objects) to match the situation with this private call
(Dimitrios’ wife’s voice, theme, emotional level). In a first attempt, Dimitrios’ ‘avatar-like’ voice runs
a brief conversation with Dimitrios’ wife, with the intention of negotiating a delay while explaining
his current situation.
Simultaneously, Dimitrios’ D-Me has caught a message from an older person’s D-Me, located in the
nearby metro station. This senior has left his home without his medicine and would feel at ease
knowing where and how to access similar drugs in an easy way. He has addressed his query in
natural speech to his D-Me. Dimitrios happens to suffer from similar health problems and uses the
same drugs. Dimitrios’ D-Me processes the data available to offer information to the senior. It
‘decides’ neither to reveal Dimitrios’ identity (privacy level), nor to offer Dimitrios’ direct help (lack
of availability), but to list the closest drug shops, alternative drugs and contacts to a self-help group
and medical contacts nearby in case of emergency. This information is shared with the senior’s D-
Me, rather than with the senior himself, to avoid useless information overload.
The D-Me is equipped with voice, pattern and patch recognition capacity. It has to identify places
and people, but also to register enough data to record the relevant events of Dimitrios’ life to
process it in its DMe profile and offer it to other DMe’s.
AmI opportunities
Functions of pattern and patch recognition can have an important impact on access to information
by blind people.
Meanwhile his wife’s call is now interpreted by his D-Me as sufficiently pressing to mobilise
Dimitrios. It ‘rings’ him using a pre-arranged call tone. Dimitrios takes up the call with one of the
available ‘Displayphones’ in the cafeteria. Since the diffusion of D-Me, fewer people run around
with mobile terminals. Public and private spaces have display terminals and your D-Me can point
at the closest….functioning one!
Problems
Possible problems in localising the displayphone.
Possible solutions
The P-com can communicate with the displayphone and, in cooperation with AmI, helps navigation
to it.
Alternatively Dimitrios can wear a special P-com that allows him to communicate directly with his
wife.
AmI opportunities
The selection of different telecommunication facilities is available.
317
Appendix I. Scenarios for people
who are not able to see
Dimitrios’ wife hates his D-Me. She suspects him living parallel lives and whatever the practical
aspects, she definitely would prefer having himright away on the phone. It has been a source of
conflict from the start.
The ‘emergency’ is about their child’s homework. While doing his homework their 9 year-old son is
meant to offer some insights on everyday life in Egypt. In a brief 3-way telephone conference,
Dimitrios offers to pass over the query to the D-Me to search for an available direct contact with a
child in Egypt. Ten minutes later, his son is videoconferencing at home with a girl of his own age,
and recording this real-time translated conversation as part of his homework. All communicating
facilities have been managed by Dimitrios’ D-Me, even while it is still registering new data and
managing other queries. The Egyptian correspondent is the daughter of a local businessman, well
off and quite keen on technologies. Some luck (and income…) had to play a part in what might
become a long lasting new relationship.
AmI opportunities
For a blind person, normally communicating by voice an automatic translated conversation could
be particularly useful.
Managing a service while choosing the best telecommunication means for the videoconference
forms part of the role of the D-Me.
3. Carmen
Original scenario
The driver is part of a carpooling scheme of the transport management systems in the urban area
where Carmen lives. Advanced payment and transactions systems are in place, which are able to
calculate the amount of money that goes to the driver and the amount that goes to the transport
operators.
It is a normal weekday morning. Carmen wakes and plans her travel for the day. She wants to leave
for work in half an hour and asks AmI, by means of a voice command, to find a vehicle to share
with somebody on her route to work. AmI starts searching the trip database and, after checking the
willingness of the driver, finds someone that will pass by in 40 minutes. The in-vehicle biosensor has
recognised that this driver is a non-smoker – one of Carmen requirements for trip sharing. From
that moment on, Carmen and her driver are in permanent contact if wanted (e.g. to allow the driver
to alert Carmen if he/she will be late). Both wear their personal area networks (PAN) allowing
seamless and intuitive contacts.
Problems
Need of special arrangements for travelling and meeting.
Possible solutions
For the trip sharing, the Carmen’s Aml informs the driver of her profile’s data related to her
disability, the destination and time details of the desire route, the way that he or she will recognise
her at a meeting point, and the parameters for establishing (PAN) connection from the moment that
they will agree.
The driver is notified of Carmen’s disability as this may have certain implications, for example in
arranging the meeting point.
318
Appendix I. Scenarios for people
who are not able to see
AmI opportunities
AmI knows the abilities/disabilities of Carmen and, if authorised by her, can use this information for
helping in arranging her travelling to work.
Objects can be tracked through radio-frequency identification tags. These e-tags are very small,
maximum of the size of a grain of rice and can be embedded in everyday objects. Everyone carrying
a device equipped with a reader could access additional information and services relating to the
tagged item.
AmI opportunities
Tags can be very useful for blind people. They can offer information to the blind persons or can be
interrogated by them.
While taking her breakfast coffee Carmen lists her shopping since she will have guests for dinner
tonight. She would like also to cook a cake and the e-fridge flashes the recipe. It highlights the
ingredients that are missing: milk and eggs. She completes the shopping on the e-fridge screen and
asks for it to be delivered to the closest distribution point in her neighbourhood. This can be a shop,
the postal office or a franchised nodal point for the neighbourhood where Carmen lives. All goods
are smart tagged, so that Carmen can check the progress of her virtual shopping expedition, from
any enabled device at home, the office or from a kiosk in the street. All goods are smart tagged, so
that Carmen can check the progress of her virtual shopping expedition, from any enabled device at
home, the office or from a kiosk in the street. She can be informed during the day on her shopping,
agree with what has been found, ask for alternatives, where they are and when they will be
delivered.
Problems
Need of alternative communication with the environment.
Possible solutions
Carmen’s P-com in communication with her e-fridge voices the recipe.
The system concludes by listing the missing ingredients.
Carmen completes the shopping list through brief voice commands.
When Carmen is connected to the shop, all the information stored in tags is translated in a properly
encoded format for her to receive. Carmen may choose to hear or read (e.g., in Braille) brief
descriptions of the goods, or to have a full presentation of a particular product or store shelf.
Presentations may contain information for the product characteristics (size, colour, and weight), the
packing, the price, potential offers or alternative selections and other information that will help her
to make her choice. Carmen’s P-workstation enables her to explore and manipulate 3D models and
artefacts by means of tactile interaction.
AmI opportunities
The wide availability of speech interfaces is very important for blind people.
Tags in connection with telecommunication networks can help in exploring the local and remote
environment.
Tactile displays are supposed to be widely available.
319
Appendix I. Scenarios for people
who are not able to see
In this scenario the environmental management system is not only connected to sensors that
control vehicle engines or the police, which in case of accidents can transfer information to the
traffic control network to re-route traffic. The system is also able to alert individuals with allergies
to certain types of pollutants when a dangerous threshold is reached. Individuals will be informed
of the unhealthy atmosphere and can decide whether to go out or stay home.
Forty minutes later Carmen goes downstairs onto the street, as her driver arrives. When Carmen
gets into the car, the VAN system (Vehicle Area Network) registers her and by doing that she
sanctions the payment systems to start counting.
Problems
Difficulties in reaching
