The objective of EnterTrain is to offer a personalized exergame platform for older adults living
alone in their private homes. Physical activity is seen as essential for this user group in
order to maintain an active lifestyle and participating in society, and thus the project aims at
enhancing their physical fitness by motivating them to exercise. However, the solution is not
only driven by the entertainment aspect, but also by an autonomous and continuous adaptation
to the variable and changing end-users’ abilities. This personalization feature is not only
innovative from a technical and market point of view, but also indispensable to be accepted
by a wide range of older adults. It is achieved by unobtrusive mobility monitoring in order to
determine the physical limitations of the user as well as by a continuous analysis of the playing
habits to determine individual preferences. The aimed product of EnterTrain is a plugand-
play device consisting of commercial off-the-shelf devices: a small processing unit and a
common 3D sensor with total costs below € 300. The 3D sensor is used both for the automatic
personalization by means of continuous movement and behaviour evaluation as well as for
the controller-less use of the exergame platform. Due the common sensor type and the open
architecture of the proposed system, additional features like fall detection can be easily integrated
for an increased value of the product. End-users are involved from the very beginning
of the project to ensure that their various needs are considered and a holistic solution is
reached in the end. The involvement is centred on a user requirement analysis and pilot application
whose outcomes are continuously integrated in the technical development process.
The pilot application is divided into two phases: phase 1 aims particularly at increasing usability
and acceptance, whereas impact evaluation is the focus of phase 2.
