Abstract: The project Smart VitAALity the Carinthian pilot region for AAL and Smart Living Technologies was
realized in Austria between 2016 and 2019. The one-year field trial focused on testing and evaluating a set of
technologies with accompanying services to improve the health and wellbeing of older adults. During this
time, various parameters regarding the usage of the different services and devices were recorded. This paper
presents an insight into the results of the usage analysis with a focus on provided support material and the
documentation of the established human-driven support activities. The investigation shows that there are
synergies between the constantly high system usage during the field test and the provided support
opportunities.
1 INTRODUCTION
Today’s societies are facing challenges like climate
change and lots of trends such as globalization,
digitization and the demographic change, which also
interfere with each other (Petersen & Steiner 2019).
The last one demographic change has been seen
as an important topic in the European Union (EU) and
its member states for more than ten years. As a result,
the funding programme AAL Joint Programme
1
(for
Active and Assisted Living) was created, which sets
the ground for the research and development of
assistive technologies for older adults. The
programme is available to several member states of
the EU, all of which are committed to open up and
develop new technologies so far mostly used by
younger people to older adults and thus allowing
them to live a longer independent life.
1.1 Pilot Regions in Austria
Almost at the same time, Austria created a similar

(28.01.2020)
research funding programme on national level called
benefit

. Within this programme, collaborative
projects are realized to develop and test technologies
which ease the life of older adults in many ways.
After several years of funding research and
development projects, the benefit programme
management figured out that lots of technologies
have already been developed and that ways need to be
found on how to open markets for them.
As a consequence, in 2012, calls
3
for so called test
region projects
4
were opened. Nine projects around
assistive technologies for older adults (seven of them
described in Ates et al., 2017) have been started since
then and many of them have already finished in the
meantime. The major goals of those projects and the
technologies to be used and tested within them were
chosen by the consortia and therefore varied among
the different projects, but they had similar framework
conditions, e.g., more than 100 persons or households
should be part of the tests and the tests should run at
least for one year. Some requirements for
dissemination activities were also defined like setting

up demonstration apartments which can be visited by
interested persons for the purpose of gaining
information about the project and the specific
technologies and services offered by them.
Beside the differences in goals and technologies,
the projects also defined different ways how to
involve the (potential) end-users of their systems and
how they are supported before, during and after the
test phase. In one of the mentioned pilot regions, a
structured support-system was implemented for
participants which offered different action
possibilities. The evaluation results of the necessary
effort to maintain the delivered technology and
services will be presented in this paper.
1.2 The Project Smart VitAALity
The cooperative research project Smart VitAALity
5
is a pilot region in the center of Carinthia, Austria
with the aim to implement AAL hardware and
services to improve the daily living of seniors at home
and empower them in using new state of the art
technologies. For the project, 227 people were
recruited, 104 people received all the technologies
and services (intervention group) and the other group
was classified as the control group without any
interventions in the one year of pilot testing (Majcen
et al., 2019; Ströckl et al., 2019).
As main interaction technologies, the participants
in the intervention group received a tablet computer
with a self-implemented Smart VitAALity
application and a smartwatch with an emergency call
system and a step counter. Furthermore, they got vital
parameter measurement devices for their blood
pressure, blood glucose and body weight; all of them
transferred the measured data via Bluetooth LE® or
ANT+ to the project server. As accompanying
services, they were able to join to a care center with
professional medical employees who had a look at
relevant parameters, intervened when necessary and
added a 24/7 call center to their emergency alarm call
chain (Majcen et al. 2019; Ströckl et al. 2019).
The described technical system and services were
developed based on the user-centered design process,
which means the later end users and other related
stakeholders were involved already in the
requirement analysis (Krainer et al. 2018). Thus, the
user-focused process was also pursued in the testing
phase of the project. In this paper, the focus is set on
a specific direct service provided to the intervention
5
Project Smart VitAALity - https://www.smart-
vitaality.at/ (28.01.2020)
group during the testing phase: the technical support
process, which will be further explained in chapter 2.
In 2019, the project ended after the testing phase
with the finalization of the evaluation process. To this
end, different parameters were collected during the
project to evaluate the subjective quality of life,
acceptance, socio-economical potential analysis,
technology acceptance, user experience and usage.
The comprehensive evaluation model provides the
basis for anchoring the Smart VitAALity system and
service model on the market (Plattner et al. 2018).
2 METHODS
This chapter describes two parts of the evaluation
model in detail: the usage analysis and the
implementation and evaluation of the technical
support process.
2.1 Usage Analysis
To evaluate the frequency of use of the Smart
VitAALity system, the usage behavior patterns of
participants were surveyed during the one-year test
phase and subsequently analyzed. During the
analysis, a basic distinction was made between
different types of data like direct data (usage logging
of the Smart VitAALity app), indirect data (e.g.
number of steps counted by the watch, from which the
watch usage is derived) as well as surveys of usage
behavior, which were carried out at the end of the
field test. The use of the Smart VitAALity tablet was
recorded using the open web analytic platform
Matomo
6
. In this way, it was possible to track
elementary interaction elements within the project
application, e.g., button clicks and opening screens.
However, since Matomo can only record usage data
of self-implemented applications, third-party apps
such as an e-mail program or WhatsApp
7
, which were
integrated into Smart VitAALity, could not be
recorded directly. In addition, other applications,
which were used on the tablet but outside of the
project application, could not be captured with
Matomo. In order to be able to make comparable
statements about the use of third-party applications
and about the general tablet use, the user behavior
was obtained in subjective interviews. To evaluate the
usage of the Smart VitAALity application, the total
usage (12 months) of each participant was divided

into three phases, since not all participants received
the system at the same time and therefore the usage
calculations could not be carried out based on the
actual calendar date. The first month represents the
initial phase, which includes the training phase for the
systems and merely shows whether there was a high
interest from the participant’s point of view at the
beginning. The second phase shows the actual use of
Smart VitAALity and lasts 10 months. The phasing
out phase represents the last month of use of each
participant and within this period, people tended to
use the devices less often, or if errors occurred, they
did not report it to the support team anymore, as the
year of testing was coming to an end.
In addition to the evaluation of the usage behavior
in consideration of the different phases, the analysis
of the frequency of use was also carried out on
extended dimensions such as gender, age, user type
and place of residence.
2.2 Support Evaluation
The planning and conduction of necessary support
processes and resources turned out to be rather
difficult. Technical support was already performed in
other pilot regions in different variations. Based on
experience reports, the different options were:
splitting up the support based on different system
components, so every component-owner is the direct
contact point for related support questions or using
one single contact point and performing the technical
support together with other provided services (e.g.
during the telemedicine process). However, regarding
needed time and financial resources, little to no
documentation existed. Nevertheless, it must be kept
in mind that within a pilot region usually a system
prototype with a technology readiness level (TRL)
8
below 8 is tested. The technology of Smart
VitAALity was categorized as level 7 at the
beginning. This means a system prototype was tested
in the future operational environment, and therefore
technical problems and issues have to be kept in mind
during planning processes. Experiences from other
pilot regions showed that the necessary technical
support process was often underestimated and not
well-considered during the planning of the field trial.
As a consequence, it was decided to create a
comprehensive documentation of all support
activities during the pilot test of the Smart VitAALity
system. To capture required first-level support
operations, an adjusted software documentation tool
8
Technology Readiness Levels (TRL) - https://ec.
europa.eu/ research/participants/data/ref/h2020/other/
was implemented based on web technologies. The
focus was set on the documentation of telephone
calls, driving times and stay times during service trips
and a categorization and processing of arising
problems and incidents in an issue-tracking-system.
Each ticket provides the framework to process a
problem according a standardized workflow and
documents the interaction with participants (Plattner,
2020).
2.3 3-step Support Model
Due to the fact that there was a limited possibility to
draw on documentation or evaluation of already
performed support processes in pilot projects, a new
process was developed. For the Smart VitAALity
project, it was important to design a functional
support model, to assist the 104 participants in the
intervention group in the best way possible.
Therefore, the project team decided to support
participants in a three-step model which is presented
in Figure 1. Each step provides a different interaction
possibility. As a first step, a printed manual was
developed. It comprises detailed explanations of
every component and function including pictures as
well as textual descriptions and step-by-step
instructions to make the available interaction with
each
function as clear as possible. It was handed out
Figure 1: 3-step support model developed for the pilot
region Smart VitAALity.

to all participants during the system roll-out. Next, the
printed handbook was digitized and inserted as a
separate function into the Smart VitAALity
application on the tablet. Thus, participants were able
to choose how to read the instructions, like an e-book
on the tablet computer or like a normal book in a
printed booklet. Both information/support options are
meant to assist participants to get familiar with the
system there is no communication or any other
interaction with humans provided. This provides low-
barrier access to information about the system,
especially for persons with almost no or low technical
experience. As a third support option for Smart
VitAALity participants, a communication-based
support alternative was provided. During the field test
phase, participants could call the technical first-level
support hotline from Monday to Friday between 8 am
and 4 pm and ask for help. If it was not possible to
solve problems and issues through the telephone call,
support employees drove to participants’ homes and
provided on-site service. The three different options
were meant to interlock as a support combination /
alternatives for participants, as shown in Figure 1.
Before starting the field trial, the development
team created different theories about the usage from
the different support options. The theories were:
1. Participants of the selected target-group (60-85)
are used to printed books and will preferably use
the instructions in the printed manual.
2. For more technically experienced people, the e-
book version will be the preferred option to use
because it is always available (no extra book to
carry).
3. Participants will tend to hesitate to call the
technical support hotline because of personal
reasons such as sense of shame or polite
reluctance.
At the end of the field test, these questions were
meant to give an idea which support options are
preferred and should be integrated in a pilot region
and which are maybe obsolete for future projects.
3 RESULTS
In this section, an overview of the results from the
evaluation of the support model is presented. The
results are clustered according to the three steps of the
support model.
3.1 Usage of Printed Manuals
As shown in Figure 2, 58% of participants answered
at the deinstallation survey (n=98) that they had used
the printed manual and 10% had used the printed
manual in combination with the e-book version. As a
result, 68% of participants used the written support
instructions (Step 1 and 2 of the support model).
In addition, participants answered an open
question on the frequency in which they had used the
two manual options. The informal answers were
clustered as
unique - answers like "used it once" during
the whole test time,
seldom - answers like "I used it very seldom"
or "I used it just to look up telephone
numbers",
sometimes - answers like "I didn't use it very
often but sometimes" or "I used it from time
to time",
regular - answers like "I used it regularly" or
"I used it once a week" and
initially - which means that users added to
their answer that they just used it at the
beginning of the test time no matter how
often.
Furthermore, 30% mentioned that they had never
used the manual. Only 10% of participants had used
the printed manual on a regular basis, 15% of
participants had used the manual just at the beginning
of the project to get used to the Smart VitAALity
system. The usage of the printed manual is visualized
in Figure 3.

printed and e-book version.

Figure 3: Clustering of statements regarding usage
frequency of the printed manual.
3.2 Usage of e-Book Manual
As shown in Figure 2, only around 6% of participants
used the e-book exclusively, and another 10% used
the e-book together with the printed manual. At the
beginning of the testing phase, an initial questionnaire
was done with all participants. In this, around 71
participants reported that they are used to
technologies like smartphones. Therefore, the
hypothesis was that they may use the e-book manual
more likely, but this was not the case. For follow-up
projects, it should be reconsidered if e-book versions
of manuals are necessary. The required resources to
create the electronic manual and its benefits should
definitely be weighed.
Having a closer look at the statements of
participants using the e-book manual it becomes
clearer that the development of such an option was
not relevant for the Smart VitAALity pilot region. All
six people answered that they had used the e-book
manual occasionally or just once at the beginning.
Figure 4: Monthly usage frequency of the e-book manual -
views and number of participants.
Figure 4 shows the use of the e-book manual on
the Smart VitAALity tablet. The total number of
button clicks and the number of people who used the
function at all is presented on a monthly basis. On
average, the e-book manual was used 41 times by 20
different people per month. Especially in the first
months of the field trial, the function was used more
frequently. Towards the end of the one-year testing
phase, the number of participants as well as the
number of button clicks decreased steadily.
3.3 Usage of First-level Support
Figure 5 shows the number of calls which were
recorded in each month of the field trial. Having a
participant number of 104, this shows a very high
motivation to contact the first-level support. 92
participants (89%) contacted the support hotline at
least once and almost every second person out of this
set had more than 4 calls with the first-level support.
This shows that the assumption regarding perceived
barriers to ask for personal support did not apply to
the participants of Smart VitAALity. It was possible
to solve most incidents via telephone but some issues
had to be tackled directly and resulted in
approximately 280 service trips. The number of
monthly service trips is also shown in Figure 5. There
is a slight decrease of necessary service trips after
eight months of the test duration. In the last two
months, no calls and trips were documented. This
may be based on the fact that the rollback of the
system already started in June 2019 and lasted until
mid of July 2019.
Figure 5: Monthly service trips and calls at the first-level
support hotline (Plattner, 2020).
3.4 Support Demand and System Usage
Another interesting perspective is the comparison of
usage frequency and support demand. To generate
comparability of support activities, the demand was
categorized in three groups based on the telephone
calls low (1), moderate (2) and high (3) usage of the
ICT4AWE 2020 - 6th International Conference on Information and Communication Technologies for Ageing Well and e-Health
184
technical support hotline. The created groups were
compared to the usage groups of the whole system
which represent low (1), moderate (2) and high (3)
usage of the Smart VitAALity system. This
comparison is visualized in Figure 6 for the whole test
duration of 12 months. It shows that the support
demand and system usage tend to overlap, especially
in the category of low and medium users. Persons
with a high system usage (group 3) also tended to
contact the hotline more often. This may result from
the fact that persons with a high system usage
frequency were more likely to come across errors and
system bugs and tried to really contribute to enhance
the system and therefore took the opportunity to use
direct personal support. Whereas persons with a low
system usage may not have been that interested in the
system at all and also tended not to contact the support
hotline in case of issues. Users categorized in the
moderate usage group also tended to contact the
support hotline on a regular basis.
Figure 6: Comparison of usage frequency and support
demand using group allocation.
4 CONCLUSIONS
The presented results show that the usage of the
system and accompanying support activities are
strongly interlinked. It was demonstrated that the
opportunity for personal contact was strongly used
throughout the whole test duration. Concerns that
participants will hesitate to use the opportunity for
personal support were not confirmed. It is hard to
determine up to which point personal support has a
direct influence on the system usage but at least it
helped to avoid bigger issues and incidents such as
transmission errors and hardware problems affecting
the system usage in a negative way. The approach to
provide only one direct contact point for participants
regarding technical issues did also have a positive
effect on the support process. Requests could be
handled very easily and a clear and structured
workflow accelerated the process of integrating fixes
and improvements to the technical system.
This process was supported by the availability of
well-structured printed manuals, which were
important especially at the beginning of the test
phase. The creation of comprehensive manuals
should also be part of follow-up projects because it
facilitates the first contact with the system, especially
for people with a low technical pre-education.
Nevertheless, it is not possible to cover all
requirements only with written materials, a personal
contact opportunity should always be provided.
The needed time and staff resources to create the
described 3-step support model were very high but
the overall feedback on the provided support process
was very positive and the constantly high system
usage over the whole test duration demonstrated that
it created a benefit for the whole project. This process
also has to be taken into account when developing the
business model for an AAL solution.
Summing up it may be said that the technical
support process is an important factor for the launch
of AAL projects and solutions, and that the necessary
resources have to be allocated already in the project
proposal.
