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.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Oscilloscope tutorial
1. Oscilloscope Tutorial
The oscilloscope is basically a graph-displaying device
It draws a graph of an electrical signal.
In most applications the graph shows how signals change
over time:
the vertical (Y) axis represents voltage
the horizontal (X) axis represents time. 65
56
45
453
6
56
35
2. Oscilloscopes
Horizontal sweeps at a constant rate. Vertical plates are
attached to an external voltage, the signal you attach to the
scope.
3.
4. Scope (Con’t)
This simple graph can tell you many things
about a signal:
You can determine the time and voltage values of
a signal.
You can calculate the frequency of an oscillating
signal.
You can see the "moving parts" of a circuit
represented by the signal.
You can tell if a malfunctioning component is
distorting the signal.
You can find out how much of a signal is direct
current (DC) or alternating current (AC).
You can tell how much of the signal is noise and
whether the noise is changing with time.
10. If a signal repeats, it has a frequency. The frequency is
measured in Hertz (Hz) and equals the number of times the
signal repeats itself in one second
12. Performance Terms
Bandwidth
The bandwidth specification tells you the frequency range the oscilloscope accurately
measures.
Rise Time
Rise time may be a more appropriate performance consideration when you expect to
measure pulses and steps. An oscilloscope cannot accurately display pulses with rise times
faster than the specified rise time of the oscilloscope.
Vertical Sensitivity
The vertical sensitivity indicates how much the vertical amplifier can amplify a weak
signal. Vertical sensitivity is usually given in millivolts (mV) per division.
Sweep Speed
For analog oscilloscopes, this specification indicates how fast the trace can sweep across
the screen, allowing you to see fine details. The fastest sweep speed of an oscilloscope is
usually given in nanoseconds/div.
13. Gain Accuracy
The gain accuracy indicates how accurately the vertical system attenuates or amplifies a
signal.
Time Base or Horizontal Accuracy
The time base or horizontal accuracy indicates how accurately the horizontal system
displays the timing of a signal.
Sample Rate
On digital oscilloscopes, the sampling rate indicates how many samples per second the
ADC can acquire. Maximum sample rates are usually given in megasamples per second
(MS/s). The faster the oscilloscope can sample, the more accurately it can represent fine
details in a fast signal..
ADC Resolution (Or Vertical Resolution)
The resolution, in bits, of the ADC indicates how precisely it can turn input voltages into
digital values.
Record Length
The record length of a digital oscilloscope indicates how many waveform points the
oscilloscope is able to acquire for one waveform record.
14. Grounding
Proper grounding is an important step when setting up to take measurements.
Properly grounding the oscilloscope protects you from a hazardous shock and protects
your circuits from damage.
Grounding the oscilloscope is necessary for safety. If a high voltage contacts the case of
an ungrounded oscilloscope, any part of the case, including knobs that appear
insulated, it can give you a shock. However, with a properly grounded oscilloscope, the
current travels through the grounding path to earth ground rather than through you to
earth ground.
To ground the oscilloscope means to connect it to an electrically neutral reference
point (such as earth ground). Ground your oscilloscope by plugging its three-pronged
power cord into an outlet grounded to earth ground.
Grounding is also necessary for taking accurate measurements with your oscilloscope.
The oscilloscope needs to share the same ground as any circuits you are testing.
Some oscilloscopes do not require the separate connection to earth ground. These
oscilloscopes have insulated cases and controls, which keeps any possible shock hazard
away from the user.
15. Scope Probes
Most passive probes have some degree of attenuation factor, such as
10X, 100X, and so on. By convention, attenuation factors, such as for the
10X attenuator probe, have the X after the factor.
In contrast, magnification factors like X10 have the X first
16. Vertical Controls
Position and Volts per Division
The vertical position control lets you move the
waveform up or down to exactly where you want it
on the screen.
The volts per division (usually written volts/div)
setting varies the size of the waveform on the
screen. A good general purpose oscilloscope can
accurately display signal levels from about 4
millivolts to 40 volts.
Often the volts/div scale has either a variable gain
or a fine gain control for scaling a displayed signal to
a certain number of divisions.
17. Input Coupling
Coupling means the method used to connect an electrical signal from one
circuit to another.
18. Horizontal Controls
Position and Seconds per Division
The horizontal position control moves the waveform from left
and right to exactly where you want it on the screen.
The seconds per division (usually written as sec/div) setting
lets you select the rate at which the waveform is drawn
across the screen (also known as the time base setting or
sweep speed). This setting is a scale factor. For example, if
the setting is 1 ms, each horizontal division represents 1 ms
and the total screen width represents 10 ms (ten divisions).
Changing the sec/div setting lets you look at longer or shorter
time intervals of the input signal.
19. Trigger Position
The trigger position control may be located in the horizontal control section of
your oscilloscope. It actually represents "the horizontal position of the trigger in
the waveform record." Horizontal trigger position control is only available on
digital oscilloscopes.
Varying the horizontal trigger position allows you to capture what a signal did
before a trigger event (called pretrigger viewing).
Digital oscilloscopes can provide pretrigger viewing because they constantly
process the input signal whether a trigger has been received or not. A steady
stream of data flows through the oscilloscope; the trigger merely tells the
oscilloscope to save the present data in memory. I
n contrast, analog oscilloscopes only display the signal after receiving the
trigger.
22. Multimeter tutorial
A meter is a measuring instrument. An ammeter
measures current, a voltmeter measures the potential
difference (voltage) between two points, and an
ohmmeter measures resistance.
A multimeter combines these functions, and possibly
some additional ones as well, into a single instrument.
23. To measure current, the circuit must be broken to allow
the
ammeter to be connected in series
Ammeters must have a LOW resistance
24. To measure potential difference (voltage), the circuit is not
changed: the voltmeter is connected in parallel
Voltmeters must have a HIGH resistance
25. To measure resistance, the component must be removed
from the circuit altogether
Ohmmeters work by passing a current through the
component being tested
26. Digital Multimeters
Digital meters give an output in numbers, usually on a liquid
crystal display.
Most modern multimeters are digital and traditional
analogue types are destined to become obsolete.
Digital multimeters come in a wide range of sizes and
capability. Everything from simple 3 ½ digit auto ranging
pocket meters to larger 8 ½ digit bench model with
operator or computer (IEEE488 compatible) settable range
selection
27. Function Generator
An electronic instrument that generates various
waveforms such as
Sine wave
Square wave
Pulse trains
Sawtooth
The amplitude, DC offset, frequency are adjustable.
28. Function Generators (con’t)
Like multimeters there is a wide variety of device
offering various
Amplitude characteristics
Bandwidth
Adjustments of rise and fall times
Modulation capability (AM, FM, Pulse, etc.)
29. Power Supply
This is the device that transfers electric power from a source to a load using
electronic circuits.
Typical application of power supplies is to convert utility's AC input power to a
regulated voltage(s) required for electronic equipment.
Depending on the mode of operation of power semiconductors PS can be linear or
switching.
In a switched-mode power supply, or SMPS power handling electronic
components are continuously switching on and off with high frequency in order to
provide the transfer of electric energy. By varying duty cycle, frequency or a
phase of these transitions an output parameter (such as output voltage) is
controlled. Typical frequency range of SMPS is from 20 kHz to several MHz.
30. Power Supply (con’t)
Power supplies like many of the other electronic instruments, come in
many varieties with a wide range of capabilities:
Parameters that are Power Supply specific include:
Voltage levels
Current
Regulation
Protection
Output impedance
Noise (ripple)
It’s the designer (or researcher) responsibility to identify the
characteristics required.
