A touchscreen device was used to produce 8 stimuli in laboratory and travelling by bus conditions. The stimuli were varied by amplitude, burst number and rise time. 10 participants were to rate the stimuli using four emotion related bipolar scales: pleasantness, arousal, approachability, and dominance. The results showed that the stimuli were rated as more pleasant, less arousing, and less dominant in the bus than in the laboratory. The stimuli with three bursts and high amplitudes were rated as significantly more unpleasant, arousing, and dominating than the low amplitude stimuli with one burst. The results suggest that simple haptic stimulation can evoke different emotional responses. The results can be utilized when designing, for example, pleasant or dominating haptic feedback.

The basic idea was to test whether one-dimensional stimuli provided by a counterclockwise (CCW) and clockwise (CW) rotating leadscrew of a friction-based fingertip stimulator prototype can be perceived as two-dimensional directional information. Ten participants were asked to indicate the perceived direction of the

These devices present new interaction challenges as the devices are usually small in size, and also the usage environment sets limitations on the available interaction modalities. One potential interaction method could be to use gaze for input and haptics for output with a head-worn device. We built a demonstration system to show how gaze gestures could be used to control a simple information application together with head area haptic feedback for gesture confirmation. The demonstration and experiences of early user studies have shown that users perceive such an input-output combination useful.

We have developed TraQuMe: a generic system to evaluate the gaze data quality. The quality measurement is fast and the interpretation of the results is aided by graphical output. Numeric data is saved for reporting of aggregate metrics for the whole experiment. We tested TraQuMe in the context of a novel hidden calibration procedure that we developed to aid in experiments where participants should not know that their gaze is being tracked. The quality of tracking data after the hidden calibration procedure was very close to that obtained with the Tobii's T60 trackers built-in 2 point, 5 point and 9 point calibrations.

Facial expressions play a critical role in human life, providing an important channel of nonverbal communication. Automation of the entire process of expression analysis can potentially facilitate human-computer interaction, making it to resemble mechanisms of human-human communication. In this paper, we present an ongoing research that aims

This method of presentation is not suitable for the visually impaired or for users in situations where interaction is limited, like in mobile context. One possibility to present information to these kinds of users would be using melodic sounds and haptic feedback to replace graphical information. We describe a new method to redistribute graphical information to melodic sounds and haptic cues with a stick interface. We discuss the impact of this redistribution to user behavior in simple shape recognition tasks. Appropriateness of redistribution is evaluated and design recommendations given based on user behavior in modal-redistributed interaction.
