Park, Young-Woo, Hwang, Sungjae and Nam, Tek-Jin (2011): Poke: emotional touch delivery through an inflatable surface over interpersonal mobile communications. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 61-62. http://dx.doi.org/10.1145/2046396.2046423

In this paper we present Poke -- a soft and human-like remote touch technique through an inflatable surface. We aimed to design it for delivering more emotional and pleasant touches over interpersonal mobile communications. Poke enables to touch human's skin with an inflatable surface according to the other user's finger pressures and hand gestures during a phone call. It delivers different kinds of pokes and other affective touches with its inflating patterns (strengths and repetitions) and vibrations from the top of the inflatable surface. The paper also suggests affective touches such as weak/hard poke, poke and then shake, poke back and pat which can be exchanged during typical phone calls.

Hwang, Sungjae, Lee, Kibeom and Yeo, Woonseung (2010): My Green Pet: a current-based interactive plant for children. In: Proceedings of ACM IDC10 Interaction Design and Children 2010. pp. 210-213. http://doi.acm.org/10.1145/1810543.1810573

The difficulty that children have in perceiving plants as living entities has been verified by several studies. As an initial attempt to address this issue, we propose "My Green Pet", an interactive plant for children. Through this, children enjoy human-like interactions with the plant and also perceive that this particular plant is living. This is achieved by personifying a regular plant by giving it human feelings and emotions, such as pain, joy, laughter, etc. The interactive plant is implemented over a current-based framework, which enables it to recognize multiple gestures and give audio and visual feedback to the user. The effectiveness of the interactive plant on the conception of plants on children was studied with a simple user test. We observed the children interacting with "My Green Pet" and noticed interactions resembling those between people. We also noticed the children being increasingly curious about the plant, resulting in spending more time with "My Green Pet". A straight-forward questionnaire done by children revealed that the children's perception of life in plants greatly differed after showing "My Green Pet".
