2. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 2 March 25, 2024 Marble Answering Machine ▪ Marble answering machine ▪ incoming messages repre- sented by physical marbles ▪ Differences ▪ familiar physical objects show the number of messages ▪ aesthetically pleasing and enjoyable to use ▪ one-step actions to perform a task ▪ simple but elegant design with less functionality ▪ anyone can listen to any of the messages ▪ Might not be robust enough to be used in public space ▪ important to take into account where a product is going to be used Marble answering machine, D. Bishop, 1992

4. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 4 March 25, 2024 Graspable User Interfaces (1995) ▪ Direct control of electronic or virtual objects through physical handles (bricks) ▪ A brick is a new user inter- face that is tightly coupled to a virtual object ▪ Bricks are used on top of a large horizontal display surface known as the ActiveDesk ▪ GraspDraw is one particular application GraspDraw on ActiveDesk George W. Fitzmaurice, Hiroshi Ishii and William Buxton, Bricks: Laying the Foundations for Graspable User Interfaces, Proceedings of CHI 1995, ACM Conference on Human Factors in Computing Systems, Denver, USA, May 1995
5. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 5 March 25, 2024 Graspable User Interfaces (1995) … A graspable object Floor planner: multiple objects with handles and spline with multiple handles Two bricks attached to a single digital object (one acting as an anchor) Moving and rotating both bricks at the same time
6. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 6 March 25, 2024 Graspable User Interfaces (1995) … ▪ Advantages of Graspable UI design ▪ encourages two-handed interactions ▪ shifts to more specialised context-sensitive input devices ▪ allows for more parallel input specification ▪ makes use of our skills for physical object manipulations - affordances of artefacts define how we use the interface ▪ externalises traditionally internal computer representations ▪ facilitates interactions by making interface elements more "direct and manipulable" by using physical artefacts ▪ takes advantage of our spatial reasoning skills ▪ affords multi-person collaborative use ▪ … ▪ Foundations of tangible interaction
7. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 7 March 25, 2024 Affordances ▪ Term affordance introduced in 1977 by psychologist James J.Gibson in the 'The Theory of Affordances' ▪ originally defined as all possible actions with an object in an environment independent of an individual's ability to recognise these actions ▪ Don Norman refined the term affordances in the context of human-machine interaction ▪ only those possible actions with an object that can be recognised by an individual ▪ an affordance of an object tells us something (gives us a clue) about how to use the object ▪ good interaction design will take affordances and the related discoverability into account
