This paper compares an emergent interaction modality for the In-Vehicle Infotainment System (IVIS), i.e., gesturing on the steering wheel, with two more popular modalities in modern cars: touch and speech. We conducted a betweensubjects experiment with 20 participants for each modality to assess the interaction performance with the IVIS and the impact on the driving performance. Moreover, we...

The predictive qualities of operator characteristics for process control performance : the influence of personality and cognitive variables

Burkolter, Dina ; Kluge, Annette ; Sauer, Jürgen ; Ritzmann, Sandrina

In: Ergonomics, 2009, vol. 52, no. 3, p. 302-311

This article examines the relationship between operator characteristics and process control performance. The findings suggest that consideration of cognitive ability and cognitive flexibility be increased in personnel selection for complex work environments.

The effects of heuristic rule training on operator performance in a simulated process control environment

Sauer, Jürgen ; Burkolter, Dina ; Kluge, Annette ; Ritzmann, Sandrina ; Schüler, Kerstin

In: Ergonomics, 2008, vol. 51, no. 7, p. 953-967

In complex work environments, the occurrence of novel system states represents a particular challenge for the design of training. This article is concerned with the use of heuristic rules to prepare operators for the management of unfamiliar fault states. An experiment was carried out to examine the effects of heuristic rule training on operator performance and system management behaviour.
