Detecting differences with magnetoencephalography of somatosensory processing after tactile and electrical stimuli.
2018
Abstract Background Deviant stimuli within a standard, frequent stimulus train induce a cortical somatosensory mismatch response (SMMR). The SMMR reflects the brain’s automatic mechanism for the detection of change in a somatosensory domain. It is usually elicited by electrical stimulation, which activates nerve fibers and receptors in superficial and deep skin layers, whereas tactile stimulation is closer to natural stimulation and activates uniform fiber types. We recorded SMMRs after electrical and tactile stimuli. Method 306-channel magnetoencephalography recordings were made with 16 healthy adults under two conditions: electrical (eSMMR) and tactile (tSMMR) stimulations. The SMMR proto…
Embracing water, healing pine : touch-walking and transcorporeal worldings
2023
This article considers touch as an embodied worlding practice in the context of humans intentionally seeking tactile trans-species contact. In particular, it examines three co-researchers’ tactile relations with tree(s) and water which were explored by “touch-walking,” an immersive method developed for this study. The method opened possibilities for examining transcorporeal sensory matterings and affective flows between the researcher’s body, co-researchers’ bodies and more-than-human bodies. This experimental micro-research brings knowledge about how people form deeply meaningful relationships with natural bodies, making worlds by cherishing tactile contact with them. Theoretically, we “po…
Hand-Held texting is less distracting than texting with the phone in a holder: anyway, don't do it
2015
We studied the effects of texting while driving and the effects of mobile phone position (hand-held, holder) on drivers' lane-keeping performance, experienced workload, and in-car glance durations in a motion-platform driving simulator with 24 participants. Overall, we found the known negative effects of texting on lane-keeping performance, workload, and visual attention on road, suggesting that texting on the road in any manner is not risk-free. As a novel finding, we found that hand-held texting led to fewer lane-keeping errors and shorter total glance times off road compared to texting with the phone in a holder. We suggest the explanation is that the drivers had considerably more experi…
Aktiivitaulun käyttö toisen asteen ammatillisessa oppilaitoksessa
2012
Tutkielmassa kartoitettiin aktiivitaulujen käyttöä toisen asteen ammatillisessa koulutuksessa toteuttamalla kysely opiskelijoille ja opettajille. Tutkimuksessa selvitettiin, kuinka opiskelijat ja opettajat kokevat oppimisen ja opettamisen luokkahuoneessa, jossa on käytössä aktiivitaulu. This Master’s Thesis researched the usage of Interactive Whiteboards in Voca-tional Education. Survey was conducted to students and teachers who have experience about Interactive Whiteboards in learning. The research was focused on the question, how students and teachers experience the learning and teaching in the classroom equipped with Interactive Whiteboard.
The effect of alertness and attention on the modulation of the beta rhythm to tactile stimulation
2021
Abstract Beta rhythm modulation has been used as a biomarker to reflect the functional state of the sensorimotor cortex in both healthy subjects and patients. Here, the effect of reduced alertness and active attention to the stimulus on beta rhythm modulation was investigated. Beta rhythm modulation to tactile stimulation of the index finger was recorded simultaneously with MEG and EEG in 23 healthy subjects (mean 23, range 19–35 years). The temporal spectral evolution method was used to obtain the peak amplitudes of beta suppression and rebound in three different conditions (neutral, snooze, and attention). Neither snooze nor attention to the stimulus affected significantly the strength of…
Browsing the information highway while driving: three in-vehicle touch screen scrolling methods and driver distraction
2012
Distraction effects of three alternative touch screen scrolling methods for searching music tracks on a mobile device were studied in a driving simulation experiment with 24 participants. Page-bypage scrolling methods with Buttons or Swipe that better facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations and thus, on less severe distraction effects than Kinetic scrolling. As predicted, Kinetic scrolling induced decreased visual sampling efficiency and increased visual load compared to Swipe, increased experienced workload compared to both Buttons and Swipe, as well as decreased lane keeping accuracy compared to ba…
Social Robots and Human Touch in Care : The Perceived Usefulness of Robot Assistance Among Healthcare Professionals
2019
Touching in care work is inevitable, particularly in cases where clients depend on nurses for many activities of daily living, such as bathing, dressing, lifting and assisting. When new technologies are involved in nurse–client relationships, the significance of human touch needs special attention. Stressing the importance of practitioners’ opinions on the usage of robots in care environments, we analyze care workers’ attitudes toward robot assistance in the care of older people and reflect on their ideas of the embodied relationship that caregivers and care receivers have with technology. To examine nurses’ attitudes toward care robots, we use survey data on professional care workers (n = …
Kosketuksen merkitys
2009
Tutkielmassa tarkastellaan fyysisen kosketuksen merkitystä ihmiselle kirjallisuuden, aiempien tutkimusten ja suomalaisille nuorille ja aikuisille teetetyn kyselylomaketutkimuksen pohjalta. Keskeisiä kysymyksiä ovat kosketuksen tarpeellisuus ihmiselle, millaista tarpeellinen kosketus on ja mitkä tekijät estävät ihmisiä koskettamasta toisiaan enemmän. Aihetta käsitellään laajasti ja kirjallisuus on tutkimuksen ohella merkittävässä osassa. Myös koululuokassa tapahtuvaa kosketusta tarkastellaan. Kirjallisuus- ja tutkimuskatsauksessa paneudutaan muun muassa myönteisen kosketuksen perustekijöihin, kulttuuri- ja sukupuolieroihin ja kosketuksen merkitykseen ihmisen elämänkaaressa. Lisäksi viitataan…

Käyttöliittymäkehitys kosketuskäyttöisille älypuhelimille
2012
Kosketusohjauksen ja sovelluskauppojen läpimurron seurauksena älypuhelinvalmistajat ovat viime vuosina panostaneet entistä enemmän laitealustojensa käytettävyyteen sekä kolmansille osapuolille tarkoitettuihin kehitystyökaluihin. Samaan aikaan markkinoille on ilmestynyt lukuisia ratkaisuja sovellusten alustariippumattomaan toteutukseen. Tässä työssä tutustutaan sovelluskehittäjille tarjottuihin vaihtoehtoihin käyttöliittymäkehityksen perspektiivistä ja selvitetään ovatko yleistyvät web-pohjaiset alustariippumattomat ratkaisut varteenotettava vaihtoehto natiiveille kehitystyökaluille. Following the rise of app stores and touch user interface driven smartphones in the recent years, practically…
