“Three-State Model of Graphical Input”

by William A.S. Buxton (1990) “All input devices are not created equal in their capabilities, nor input techniques in their demands.” 6 Generic Transactions of User’s Intentions with a Device (Foley, Wallace, Chan 1984) select an object position an object orient an object ink (draw a line) text (enter text) value (specify a scalar value) [ READ MORE ]

“Getting a Grip on Tangible Interaction”

“…A Framework on Physical Space and Social Interaction” by Eva Hornecker, Jacob Buur (2006) A framework for the interweaving of the material/physical and the social aspects of tangible interaction. Framework: Tangible Manipulation: material representations with distinct tactile qualities, which are typically physically manipulated in tangible interaction. Spatial Interaction: tangible interaction is embedded in real space, [ READ MORE ]

“Integrated Keyboard and Pointing Device System”

Patent #5124689 (Google Patents) (1992) “A computer system employs an integrated keyboard and pointing device to allow user input of alpha-numeric (typing) information, pointing direction information and pointing event information without moving the users’ hands from the usual typing position on the keyboard.” “One of the keyboard keys, called the pointing key, has sensors coupled to it to acquire pointing direction [ READ MORE ]

“When it gets more difficult, use both hands”

“…Exploring Bimanual Curve Manipulation” by Russell Owen, Gordon Kurtenbach, George Fitzmaurice, Thomas Baudel, Bill Buxton (2005) Investigated “…relationship between bimanual (two-handed) manipulation and the cognitive aspects of task integration, divided attention and the epistemic action.” “We provide evidence that the bimanual technique has better performance than the unimanual technique and, as the task becomes more [ READ MORE ]

“Think Before You Talk”

“…An empirical study of Relationship between Speech pauses adn Cognitive Load” by M. Asif Khawaja, Natalie Ruiz, and Fang Chen (OzCHI 2008) Speech pauses are useful indicators of high load versus low load speech. Cognitive load refers to the amount of mental demand imposed on a person by a particular task, and has been associated [ READ MORE ]

“Tangled Interaction”

“…On the Expressiveness of Tangible User Interfaces” by Johan Redström “…aesthetic potential of overloading the object’s surface by adding several layers of interaction.” “…how through a certain design we aim to make a computational thing express what it can do through the way it presents itself to us through use over time.” Differences between designing [ READ MORE ]

“Pinning objects to wall-sized displays”

“Blurring the line between real and digital: Pinning objects to wall-sized displays” by Daniel Stødle, Otto J. Anshus (2008) Attempt to replicate the interaction and experience of a “billboard” through advanced technology. A “billboard” being an area on a wall, or a bulletin board, where you can post small messages, posters for events, or “wanted” [ READ MORE ]

“PreSense”

“…Interaction Techniques for Finger Sensing Input Devices” by Jun Rekimoto, Takaaki Ishizawa, Carsten Schwesig, Haruo Oba (UIST 2003) “PreSense is a keypad that is enhanced by touch (or proximity) sensors based on capacitive sensing.” A normal physical button pad with touch sensing on top of each key. Extension of previous “SmartPad” system. Essence of direct [ READ MORE ]

“SmartPad”

“…A Finger-Sensing Keypad for Mobile Interaction” by Jun Rekimoto, Takaaki Ishizawa, Haruo Oba (CHI 2003) “…a new input device for mobile computers that is an enhanced physical keypad by a finger position sensor.” “…combines two input sensors; one is a normal physical keypad, and the other is a finger position sensor based on capacitive sensing.” [ READ MORE ]

“Touch&Type”

“…A Novel Pointing Device for Notebook Computers” by W. Fallot-Burghardt, M. Fjeld, C. Speirs, S. Ziegenspeck, H. Krueger, T. Läubli (NordiCHI 2006) “…combines a conventional keyboard with an extended touch pad whereby the touch pad’s sensitive area is formed by the surface of the keys themselves and thus can be made as large as the [ READ MORE ]
