What does the promoted behavioral change consist of?
It is also possible to report any incorrect behaviour to the driver, for example turning on the air conditioner while keeping the windows down. The driver is made aware of his behaviour through various feedbacks, which may vary according to the context (e.g. stimuli already present in the environment) and the urgency of the message that must be communicated (type of risk that the behaviour implies).
What are the main features of the tools designed/implemented to promote behavioral change and how have they been tested?
The use of different sensory channels and stimuli with different characteristics and intensities, as well as possible combinations, is compared to verify their effects on user behaviour. The cognitive and perceptive aspects of the various feedbacks and the physiological response of the users (skin conductance, heartbeat) are also considered.
What results have been achieved? What are the potentials and obstacles?
In particular, the best results obtained concern to the use of tactile feedback, individually or combined with other stimuli, in a multisensory approach. The use of such feedback can communicate messages to the driver without further overloading the visual channels during driving, risking counterproductive effects. Possible obstacles include the acceptability of systems by users, as they are more intrusive than traditional visual feedback. Different intensities, patterns and positioning of the stimuli must therefore be experienced.
