What is HCI? Chapter 1 The human 1.3.1 Sensory memory Page 27. Thanks AirBnb for setting such an awesome example! Memory can be fickle if not properly understood, it varies from person to person and can cause some serious stumbling blocks if an interaction continues across multiple screens. There is also a focus in HCI on how to implement the computer software and hardware mechanisms to … of TEI 2013. http://multi-sensory.info/chi2016workshop/, http://www.journals.elsevier.com/international-journal-of-human-computer-studies/call-for-papers/special-issue-on-multisensory-human-computer-interaction, http://www.wired.co.uk/article/9d-television-touch-smell-taste, http://www.psy.ox.ac.uk/team/charles-spence, Sensing the future of HCI: Touch, taste, and smell user interfaces. Sensory Memories Buffers for stimuli received through the senses, one exists for every sensory channel (iconic, echoic, haptic). It acts like a buffer for signal received from the five senses of touch, smell, taste, hearing and … They are typically retained for less than 500 milliseconds. 2 The MHP Model Human Processor (MHP) Perceptual, Motor and Cognitive sub-systems The development of taste and smell interfaces, and subsequently flavor interfaces, is still in its infancy; much work will be required to create multisensory-based systems that are both meaningful to people and scalable. During every moment of an organism's life, sensory information is being taken in by sensory receptors and processed by the nervous system.  investigated the characteristics of the five basic taste experiences (sweet, salty, bitter, sour, and umami) and suggested a design framework. Here, it is key to think about congruency and its ability to produce different reactions in the user. This taste overwhelms with its rapid appearance and rapid decay. In terms of the form layout itself, I would be using implicit/tacit knowledge to navigate the form and to know how to input information from my experience with other similar forms. During his Ph.D. studies he invented virtual taste technology. ... Empirical Study to Measure the Impact of HCI Technologies on Environments and Design Framework Model for Future HCI Technology. Figure 1. 7. The designer can adjust specific tastes in each category to create different affective reactions and a sense of agency. LOLLio, the taste-based game device, currently uses sweet and sour for positive and negative stimulation during game play. 1.1.2. easy to learn. Model Human Processor (MHP) ... Sensory Memory Attention: a Scarce Resource External Stimuli What is not attended to decays Long Term Memory mental models, … The key to surmounting this hurdle, is to make the groups of information meaningful. Sometimes the form is split onto multiple pages or it can be just one long, continuous page of questions and fields. Just be aware that this allows for a margin of error, which can lead to confabulation or false memories. Taste+ is an example of how multisensory interaction could improve dining experiences (which, by definition, are multisensorial ). Sensory memory is the shortest-term element of memory. For that purpose, Haverkamp suggests that designers need to take into account different levels of interconnections between the senses, such as the relations between (abstract) sensory features in different modalities (e.g., visual shape and taste qualities) or semantic associations (e.g., as a function of a common identity or meaning) that can for instance be exploited in a multimedia context (Figure 4). People often say things like "I like it. Both require the user’s recall of memory, so we need to design for it. His research focuses on mixed reality, HCI, wearable computers and ubiquitous computing, fuzzy systems, embedded systems, and power electronics. On the other hand, it could be explicit memory if I came to the app with a preconceived idea of specifically where I wanted to go. 2. 9D TV: An example of multisensory integration while watching a movie investigated by the SCHI "Sky" Lab team at the University of Sussex . As a community, we need to explore and develop design methods and frameworks that provide both quantitative and qualitative parameters for sensory stimulation. Finally, it is vital to understand what limitations come into play when users need to monitor information from more than one sense simultaneously. Whilst we may believe that our memories are finely tuned, accurate representations of the world, all memories are constructed by our brains. It could either be associative or explicit too. C.Vi@sussex.ac.uk, Nimesha Ranasinghe (http://nimesha.info) is a research fellow at the National University of Singapore. For example, Michael Haverkamp  has put forward a framework for synesthetic design. HCI Foundations: Human Technology Humans Task Design Organizational & Social Issues 2 1. For instance, Obrist et al. The goal is that by understanding the ways in which our senses process information and how they relate to one another, it will be possible to create richer experiences for human-technology interactions. However, there could be an element of sensory memory if I scroll past a house that immediately catches my eye. Although our knowledge about sensory systems and devices has grown rapidly over the past few decades, there is still an unmet challenge in understanding people's multisensory experiences in HCI. In this way, it supports my short-term memory and does the mezzanine and long-term memory for me. 3. Pavlov’s dogs. email@example.com. The dual process theory, for instance, accounts for two styles of processing in humans: the intuition-based System 1 with associative reasoning that is fast and automatic with strong emotional bonds; and reasoning based on System 2, which is slower and more volatile, being influenced by conscious judgments and attitudes. His research focuses on crossmodal perception and its applications. However, there are still many challenges when studying taste and particularly smell, especially related to inter-subject variability, varying olfactory preferences over time, and cross-sensory influences. We also propose the basic termi- nology to convert sensory memory to long term memory. Now just remember the number of letters in each group and it’s easy! It is generally agreed that there are three types of memory or memory function: sensory buffers, short-term memory or working memory, and long-term memory. To copy otherwise, to republish, to post on servers or to redistribute to lists, requires prior specific permission and/or a fee. playing an instrument. Figure 3. Wired (May 20, 2016); http://www.wired.co.uk/article/9d-television-touch-smell-taste, Marianna Obrist is a reader in interaction design at the University of Sussex, U.K., and head of the Sussex Computer Human Interaction (SCHI "Sky") Lab (http://www.multisensory.info/). This article introduces the recent trends towards "embodied cognition." A sensory memory exists for each sensory channel: Proc. It has the capability to preserve the information for very short period of time after the original stimuli have ended. I can also feel Miller’s 7±2 rule working on me, as I forget results which were passed more than 5/7 scrolls ago. Usability. Bearing this in mind, we will consider the way in which memory is structured and the activities that take place within the system. However, we are now ahead of the technological development due to the rich understanding achieved by psychology and neuroscience. HCI Notes - ALL Units (1) NOTES. 1.1.3. flexible. Their approach to HCI is that a good interface should make information easy to remember as well as easy to deal with. 5. We thus have the opportunity to shape the development of future taste- and smell-based technologies (Figure 2) . Although our knowledge about sensory systems and devices has grown rapidly over the past few decades, there is still an unmet challenge in understanding people's multisensory experiences in HCI. We do not yet know entirely how to digitize these senses in the HCI context compared with others like sound and light, where we can measure frequency ranges and convert them into a digital medium (bits). Moreover, an appropriately presented taste can create a synchronic experience that can lead to stronger cognitive ease (to make intuitive decisions) or reduce the cognitive ease to encourage rational thinking. Automatic reactions — e.g. The Digital Library is published by the Association for Computing Machinery. This framework describes the characteristics of taste experiences across all five tastes, along three themes: temporality, affective reactions, and embodiment. Attention is the concentration of the mind on one out of a number of competing stimuli or thoughts. Human Computer Interaction (CS6008) Uploaded by. important for HCI CS-364: Human –Computer Interaction Slide 5 ... sensory channel Short-term memory acts as a ‘scratch-pad’ for temporary recall of information Long-term memory Sensory stores Attention (Iconic, Echoic, Haptic) Short-term memory or Working memory Rehearsal & Information Information is passed from sensory memory to short term memory by attention. (Developed by Aromajoin). of the 6th International Conference on Body Area Networks. Attention is the concentration of the mind on one out of a number of competing Thinking : Reasoning And Problem Solving Part-1 Explained With Examples in Hindi l HCI Course - Duration: 6:16. Long-term memory stores are shown in the bottom row of boxes in Figure 2.10. Smell and taste are known as the chemical senses because they rely on chemical transduction. In the case of touch, the process is well facilitated through the proliferation of haptic technologies (from contact to contactless devices), but we are still in the early stages of development for taste and smell. Long-term memory will store things for long term so you will not forget them. Such reactions, when carefully timed, can prime users to be more rational in their thinking during a productivity task (e.g., to awaken someone who may be stuck in a loop). HCI differs from human factors and ergonomics as HCI focuses more on users working specifically with computers, rather than other kinds of machines or designed artifacts. HUMAN COMPUTER INTERACTION UNIT 1 FOUNDATIONS OF HCI The Human I O channels Memory Reasoning and problem solving The computer Devices Memory processing and. However, there could be an element of sensory memory if I scroll past a house that immediately catches my eye. Try to remember and recall the following chain of letters: HEC ATRA NUPT HET REET. Motor memories — e.g. They take in an input stimulus, perceive, encode it into alanguage which our neurons can understand and reconstruct those signals into memories for us to recall. 2. For example, sweet sensations can be used to stimulate and enhance positive experiences, though on a limited timescale, as the sweetness quickly disappears, leaving one unsatisfied. Obrist, M., Comber, R., Subramanian, S., Piqueras-Fiszman, B., Velasco, C., and Spence, C. Temporal, affective, and embodied characteristics of taste experiences: A framework for design. Perhaps, aiming for the psychological flavor sense would be a way to go, as we combine taste, olfactory, and trigeminal/oral-somatosensory inputs in our everyday life whenever we eat or drink. You just clipped your first slide! Humans have five traditional senses: sight, hearing, taste, smell, touch. of CHI 2014. Spence, C. Multisensory flavor perception. For example, we rarely experience the sense of taste in isolation. Deciding “where to go” with this screen, I felt that I could have been using short-term, mezzanine and long-term memory depending on how long it had been since I was inspired to visit the specific destination which I had in mind. HCI Lecture 3 Human capabilities: Memory and learning Barbara Webb Key points: Long term memory •organised as networks, schemas, frames Short term memory •what are the limits? It is sweet," but the underlying properties of specific and often complex experiences in HCI remain silent and consequently inaccessible to designers. Short Term Memory form. 1.3.1 Sensory memory The sensory memories act as buffers for stimuli received through the senses. This includes not only remembering lists of numbers but also passwords and how deep into the navigation flow that a user goes. They are typically retained for less than 500 milliseconds. There are three types of memory or memory function: sensory buffersshort-term , memory or working memory, and long-term memory. University.

We, the editors in chief of ACM Interactions, stand with the millions of people in the U.S. and across the globe protesting anti-Black violence and white supremacy. The immediate things which we want to record are taken up as sensory input and then shuffle it into short term memory. augmented by sensory inputs, such as environmental visuals and sounds, as well as body-relative locational information. Pretty hard isn’t it? firstname.lastname@example.org, Carlos Velasco (http://carlosvelasco.co.uk/) is a member of the Crossmodal Research Laboratory, University of Oxford, U.K., and a postdoctoral research fellow at the Imagineering Institute, Iskandar, Malaysia. 299–302. IS6421 HCI by Albert Chung 1. But can cognitive science still contribute to the newest developments? HCI Lecture 1 1. chapter 1 the human 2. the ... sensory memory • Buffers for stimuli received through senses – iconic memory: visual stimuli – echoic memory: aural stimuli – haptic memory: tactile stimuli • Examples – “sparkler” trail – stereo sound • Continuously overwritten Mezzanine memory is often overlooked and unfortunately has not been studied much outside of airplane cockpits to test for situational awareness in a simulated crisis. We can demonstrate the existence of iconic memory by moving a finger in front of the eye. I. Anna University. A key but often overlooked element of the user experience is accounting for the nuances of user memory. It sits between short and long-term memory, of the last 20–30 minutes. Lecture 5 Usability Principles 1.1. It . The field of human computer interaction (HCI) is deeply rooted in cognitive science. I might remember them if they really stood out from the others, but even then my memory was vague and not specific. Based on multisensory experience research, it is possible to think of a variety of directions for the future. This will undoubtedly provide new tools for interactive experience design and will help to uncover the fine granularity of sensory stimulation and emotional responses. We mostly rely on vision and hearing, and increasingly touch, but taste and smell remain largely unused. Whereas when a user is moving to distinct levels or is performing a side challenge, an explosive taste like sour, sweet, or umami might be more suitable. Short-term Memory HCI LEC 6 (1).pptx from BSSE SS1422 at Riphah International University Islamabad Main Campus. The Role of Memory in HCI. HUMAN COMPUTER INTERACTION LECTURE 3 Human Memory: • There are three types of memory - sensory buffers, short-term memory, For example, they have provided crucial insights on the multisensory interactions that give rise to the psychological "flavor sense" . Clipping is a handy way to collect important slides you want to go back to later. Second, we need to build on previous frameworks for multisensory design while also creating new ones. I would use associative memory if I entered a search query for a location related to one that appears in the default suggestions. 4 What is iconic memory? Furthermore, it is crucial to determine the meaningful design space for multisensory interactive experiences. •Sensory Memory •Social Organization Around the individual •External cognitive aids •Augmented Reality •Search 1 The Human HCI:Dix,et.al Long-Term Memory Working Memory Visual Image Store Auditory Image Store Perceptual Processor Motor Processor Cognitive Processor Ears … Memory is associated with each level of processing. Sensory memory allows individuals to retain impressions of sensory information … Who is the “human” in HCI (the user)? Sensory buffers will lose memory quickly. These are the memory systems for autobiographical episodes, for various kinds of knowledge, and for highly practiced expertise.
