The use of
information systems to aid disabled people is a promising use of technology for
the future. Physical disabilities such as mobility, vision, and hearing
impairment are only a few things that are being addressed through technology.
More research into these problems can bring some potentially unique and
undiscovered solutions to the forefront of technology manufacturers and
vendors. There are two research methods that may offer help in this area: the
Delphi method and the nominal group technique (NGT).
According
to Skulmoski and Hartman (2007) the Dephi method is well suited when the goal
is to improve our understanding of problems, opportunities, and possible solutions.
It is an iterative process of data collection from experts which allows them to
voice their ideas on complex problems and then revise their ideas based upon
anonymous interaction with the other experts feedback and thoughts. This method
has been used for extremely difficult and
complex issues such as nuclear proliferation and war strategies.
The nominal
group technique can be useful for collecting semi-quantitative, rank-ordered feedback
data obtained from the participant’s perceptions of the strengths and
weaknesses of an evaluated process or function such as a training program
(Dobie, Rhodes, Tysinger, & Freeman, 2004). This process has been used to
evaluate course development activities by soliciting input from participants in
a round robin fashion and then analyzing the data in rich discussions. There is
less anonymity in NGT than in the Delphi method. It is also less iterative in
nature. Based on these two methods, a complex problem such as computer
augmentation for disabled persons may be benefited most by the Delphi method of
research. Since this technology requires extreme innovation to overcome the
challenges that have impeded progress, the forecasting nature of Delphi studies
based on expert ideas may spawn creativity for new solutions. The NGT is more
of an evaluation tool, not that new ideas could not spawn from the post
discussion phase. It just seems that the “steel sharpens steel” phenomenon
would seemingly be greater in the Delphi type of interaction among experts in
the field.
