The Role of Gesture Types and Spatial Feedback in Haptic Communication
Found in: IEEE Transactions on Haptics
By Jussi Rantala,Roope Raisamo,Jani Lylykangas,Teemu Ahmaniemi,Jukka Raisamo,Jyri Rantala,Kalle Mäkelä,Katri Salminen,Veikko Surakka
Issue Date:October 2011
pp. 295-306
The sense of touch is a fundamental part of social interaction as even a short touch from another person can elicit emotional experiences. Previous studies on haptic communication indicate that the benefits of interpersonal touch exist even when touch is a...
Design of Dynamic Vibrotactile Textures
Found in: IEEE Transactions on Haptics
By Teemu Ahmaniemi, Juha Marila, Vuokko Lantz
Issue Date:October 2010
pp. 245-256
This paper describes a method for creating virtual textures without force feedback by using a simple motion sensor and a single vibrotactile actuator. It is based on wavetable synthesis driven by the user's hand movements. The output of the synthesis is re...
Demo hour
Found in: interactions
By Eunjin Kim, Hiromi Nakamura, Home Miyashita, Johan Kildal, John Vines, Kiel Long, Koray Tahiroğlu, Romy Achituv, Simon Overstall, Teemu Ahmaniemi, Thomas Svedström, Valtteri Wikström
Issue Date:January 2014
pp. 10-13
The four projects shown here are from CHI 2013 Interactivity in Paris, France, selected to reflect the diversity of approaches to embodied interaction. HCI research commonly features contributions more keenly experienced through embodied engagement rather ...
MARSUI: malleable audio-reactive shape-retaining user interface
Found in: CHI '13 Extended Abstracts on Human Factors in Computing Systems (CHI EA '13)
By Johan Kildal, Koray Tahiroğlu, Simon Overstall, Teemu Ahmaniemi, Valtteri Wikström
Issue Date:April 2013
pp. 3151-3154
MARSUI is a hardware deformable prototype exhibiting plastic (shape-retaining) behavior. It can track the shape that the user creates when deforming it. We envision that a set of predefined shapes could be mapped onto particular applications and functions....
Perceived physicality in audio-enhanced force input
Found in: Proceedings of the 13th international conference on multimodal interfaces (ICMI '11)
By Chi-Hsia Lai, Johan Kildal, Koray Tahiroglu, Matti Niinimaki, Teemu Ahmaniemi
Issue Date:November 2011
pp. 287-294
This paper investigates how the perceived physicality of the action of applying force with a finger on a rigid surface (such as on a force-sensing touch screen) can be enhanced using real-time synthesized audio feedback. A selection of rich and evocative a...
Emotional responses to thermal stimuli
Found in: Proceedings of the 13th international conference on multimodal interfaces (ICMI '11)
By Jani Lylykangas, Johannes Pystynen, Jukka Raisamo, Kalle Makela, Katri Salminen, Roope Raisamo, Teemu Ahmaniemi, Veikko Surakka
Issue Date:November 2011
pp. 193-196
The present aim was to study if thermal stimuli presented to the palm can affect emotional responses when measured with emotion related subjective rating scales and changes in skin conductance response (SCR). Two target temperatures, cold and warm, were cr...
Squeeze vs. tilt: a comparative study using continuous tactile feedback
Found in: Proceedings of the 2011 annual conference extended abstracts on Human factors in computing systems (CHI EA '11)
By Dari Trendafilov, Eve Hoggan, Roope Raisamo, Teemu Ahmaniemi
Issue Date:May 2011
pp. 1309-1314
This paper presents an investigation into the performance of squeezing as a manipulative interaction technique in comparison to tilting with an aim to answer two questions: is squeezing an effective input technique for mobile devices and can tactile feedba...
Dynamic audiotactile feedback in gesture interaction
Found in: Proceedings of the 10th international conference on Human computer interaction with mobile devices and services (MobileHCI '08)
By Juha Marila, Teemu Ahmaniemi, Vuokko Lantz
Issue Date:September 2008
pp. 1-30
Proper feedback is one of the challenges in gesture interaction. Providing continuous feedback during the execution of the gesture increases the feeling of control and it can help user to perform the task more efficiently. In this paper we introduce an exp...
