Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

7. Generations of Computer Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices.
8. TIME PERIOD : 1940's-1950's TECHNOLOGY USED : Vacuum Tubes SIZE AND SPEED : Huge, taking up entire rooms, Slow speed LANGUAGE USED : Machine language COST : System and working cost very high. OTHER FEATURES : Used a great deal of electricity. Generated a lot of heat. Input was based on punched cards and paper tape, and output was displayed on printouts. EXAMPLE : UNIVAC and ENIAC ( Electronic Numerical Integrator and Calculator ) Structure of a Vaccum Tube UNIVAC ENIAC FIRST GENERATION
9. SECOND GENERATION TIME PERIOD : 1950's- 1960's TECHNOLOGY USED : Transistors SIZE AND SPEED : Lesser size and increased speed LANGUAGE USED : Assembly language and languages like COBOL and FORTRAN COST : Cost decreased OTHER FEATURES : More efficient and reliable. Though the transistors still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output. EXAMPLE : UNIVAC 1108, IBM 1401, CDC 1604 UNIVAC 1108 IBM 1401 TRANSISITORS
10. THIRD GENERATION TIME PERIOD : late 1960's-1970's TECHNOLOGY USED : Integrated Circuit SIZE AND SPEED : Size Lesser and speed further increased LANGUAGE USED : Operating System was developed. COST : Cost decreased further OTHER FEATURES : Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors. EXAMPLE : IBM-360 series, Honeywell Model 316, Honeywell – 6000 series, CDC – 1700. IBM 360/50
11. FOURTH GENERATION TIME PERIOD : 1970's-today TECHNOLOGY USED : Microprocessor SIZE AND SPEED : Reduced size and tremendous speed LANGUAGE USED : High Level Languages like PASCAL, COBOL, C, C++, JAVA COST : Reduced Cost OTHER FEATURES : Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors. As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices. EXAMPLE : Intel 4004, Apple Macintosh The Macintosh 128K , the first Macintosh, was the first commercially successful personal computer to use images, rather than text, to communicate. Intel 4004D microprocessor
12. FIFTH GENERATION TIME PERIOD : 1990's -today TECHNOLOGY USED : Microprocessor SIZE AND SPEED : Reduced size and tremendous speed LANGUAGE USED : Based on Artificial intelligence COST : Reduced Cost OTHER FEATURES : Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization. EXAMPLE : Parallel Inference Machine Note : Artificial Intelligence is the branch of computer science concerned with making computers behave like humans. Note : Voice Recognition is the field of computer science that deals with designing computer systems that can recognize spoken words.
13. Hybrid Computers : Uses both digital and analog qualities. e.g. Digital thermometer Digital Computers : Work with digits or numbers. Types of Computer Analog Computers : Works on measurement of physical phenomenon like breath, rotation, electric effects, voltage. e.g. ECO, ECG, measuring distance traveled in KM. In car, Speedometer in car.
