Maurice Merleau-Pontyn lihan ontologiasta
2019
Minkälaista ontologista ajattelua Merleau-Ponty kehitteli myöhäisfilosofiassaan? Tarkastelen seuraavassa Merleau-Pontyn ontologian hahmotelmaa ennen kaikkea keskeneräiseksi jääneen ja postuumisti julkaistun teoksen Le visible et l’invisible (1964) muotoilujen pohjalta. Selkeytän Merleau-Pontyn teksteissä tulkinnanvaraiseksi jäänyttä lihan ontologista ulottuvuutta kahden hänen myöhäisfilosofiassaan keskeisen käsitteen, kaksoiskosketuksen ja käännettävyyden, avulla. Lihan rakenteen kuvauksessa käytän apuna Merleau-Pontyn esille nostamia taide-esimerkkejä. Esitykseni mukaan Merleau-Pontyn myöhäisfilosofian muotoilut viittaavat olemisen ajatteluun dynaamisena, aina vasta muotoutumassa olevana k…
Analysis of Somatosensory Cortical Responses to Different Electrotactile Stimulations as a Method Towards an Objective Definition of Artificial Senso…
2022
Sensory feedback is a critical component in many human-machine interfaces (e.g., bionic limbs) to provide missing sensations. Specifically, electrotactile stimulation is a popular feedback modality able to evoke configurable sensations by modulating pulse amplitude, duration, and frequency of the applied stimuli. However, these sensations coded by electrotactile parameters are thus far predominantly determined by subjective user reports, which leads to heterogeneous and unstable feedback delivery. Thus, a more objective understanding of the impact that different stimulation parameters induce in the brain, is needed. Analysis of cortical responses to electrotactile afference might be an effe…
Critical Analysis on the NHTSA Acceptance Criteria for In-Vehicle Electronic Devices
2014
We tested a commercial in-car navigation system prototype against the NHTSA criteria for acceptance testing of in-vehicle electronic devices, in order to see what types of in-car tasks fail the acceptance test and why. In addition, we studied the visual demands of the driving scenario recommended by NHTSA for task acceptance testing. In the light of the results, NHTSA guidelines and acceptance criteria need to be further developed. In particular visual demands of the driving scenario and for different simulators need to be standardized in order to enable fair testing and comparable test results. We suggest the visual occlusion method for finding a driving scenario that corresponds better wi…
Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction
2020
Visual distraction by secondary in-car tasks is a major contributing factor in traffic incidents. In-car user interface design may mitigate these negative effects but to accomplish this, design factors’ visual distraction potential should be better understood. The effects of touch screen size, user interface design, and subtask boundaries on in-car task's visual demand and visual distraction potential were studied in two driving simulator experiments with 48 participants. Multilevel modeling was utilized to control the visual demands of driving and individual differences on in-car glance durations. The 2.5” larger touch screen slightly decreased the in-car glance durations and had a diminis…
