Colour and Contrast

IMG_8448.JPG

Despite the weathered type, there is no mistaking the location and meaning of the device in the photo above.

Warm colours take control, we use them for things you want to pop out and get noticed. Colours like red are especially good for this purpose. Some colours have universal meaning, but some do not. Higher contrast items stand out and catch your eye, the white background above is very effective. The same red box placed on a red brick background is less effective, a problem I often see.

This is very basic knowledge but it’s consistent application requires a discipline I don’t often encounter in my day to day environment.


Four principles for screen interfaces

Taken from Donald Normans Affordances and Design essay comes and excellent set of conventions to help guide the design of screen based products in a way that will help users understand what actions are possible, like most design conventions, each has both virtues and drawbacks:

1. Follow conventional usage, both in the choice of images and the allowable interactions.

Convention severely constrains creativity. Following convention may also violate intellectual property laws (hello Samsung et al). Sometimes we wish to introduce a new kind of action for which there are, as yet, no accepted conventions. On the whole, however, unless we follow the major conventions, we are doomed to fail.

2. Use words to describe the desired action.

This is, of course, why menus can be relatively easy to understand: the resulting action is described verbally. Words alone cannot solve the problem, for there still must be some way of knowing what action and where it is to be done. Words can also cause problems with international adoption. It is also the case that words are understood more quickly than graphics — even a well known, understood graphic. Words plus graphics are even more readily understood.

3. Use metaphor.

Metaphor is both useful and harmful. The problem with metaphor is that not all users may understand the point. Worse, they may take the metaphor too literally and try to do actions that were not intended. Still, this is one way of training users.

4. Follow a coherent conceptual model so that once part of the interface is learned, the same principles apply to other parts.

Coherent conceptual models are valuable and, in my opinion, necessary, but there still remains the bootstrapping problem; how does one learn the model in the first place?

Though written over twenty years ago the logic still is valid today, many of my chief complaints with iOS 7 could be solved by following the above. For complete detail refer to the original article.


Robert Brunner: What All Great Design Companies Know

We emulate the design acumen of companies like Apple and BMW, but what are the processes and mindsets that make them tick? In this 99U talk, designer Robert Brunner deconstructs his creative process revealing the stories behind products like Beats by Dre headphones and the Polaroid Cube.
First, he says, recognize that a brand belongs to your customers. “You don’t own your brand. A brand isn’t a logo or packaging,” he says. “It’s a gut feeling. And when two people have the same gut feeling, you have a brand.” Secondly, most people view design as a part of the production chain, you get requirements in and out comes a product. But design is the chain, and for the best products it permeates every step. “It should be a topic of conversation constantly,” he says. “Thats how you make great stuff.”


Visual distraction and productivity

Visual distraction: a behavioral and event-related brain potential study in humans

Astract: Recent studies reported that the detection of changes in the visual stimulation results in distraction of cognitive processing. From event-related brain potentials it was argued that distraction is triggered by the automatic detection of deviants. We tested whether distraction effects are confined to the detection of a deviation or can be triggered by changes per se, namely by rare stimuli that were not deviant with respect to the stimulation. The results obtained comparable early event-related brain potential effects for rare and deviant stimuli, suggesting an automatic detection of these changes. In contrast, behavioral distraction and attention-related event-related brain potential components were confined to deviant stimuli. This finding suggests that deviancy from a given standard adds a genuine contribution to distraction.

Neural Mechanisms Underlying the Impact of Visual Distraction on Retrieval of Long-Term Memory

Filtering information on the basis of what is relevant to accomplish our goals is a critical process supporting optimal cognitive performance. However, it is not known whether exposure to irrelevant environmental stimuli impairs our ability to accurately retrieve long-term memories. We hypothesized that visual processing of irrelevant visual information would interfere with mental visualization engaged during recall of the details of a prior experience, despite goals to direct full attention to the retrieval task. In the current study, we compared performance on a cued-recall test of previously studied visual items when participants’ eyes were closed to performance when their eyes were open and irrelevant visual stimuli were presented. A behavioral experiment revealed that recollection of episodic details was diminished in the presence of the irrelevant information. A functional magnetic resonance imaging experiment using the same paradigm replicated the behavioral results and found that diminished recollection was associated with the disruption of functional connectivity in a network involving the left inferior frontal gyrus, hippocampus and visual association cortex. Network connectivity supported recollection of contextual details based on visual imagery when eyes were closed, but declined in the presence of irrelevant visual information. We conclude that bottom-up influences from irrelevant visual information interfere with top-down selection of episodic details mediated by a capacity-limited frontal control region, resulting in impaired recollection.

Showreel covering Territory’s UI concepts, design and animation for both on-set playback and VFX shots for Guardians of The Galaxy.

Beautiful work but like all UI created for movies overly complex; complexity lends itself well to delivering an idea of technological advancement, what we don’t understand is inherently advanced (and few understand onscreen UI displays).


Auditory distractions and productivity

I’ve been thinking of the effect of music, background noise or periodic sound events might have on a persons ability to learn and be productive and creative. I’ve long felt that music or sound helps with known repetitive tasks but what effects on short term or long term memory? Another question, are purposely created sound effects an aid in concentration? Some software features background sounds as an aid to concentration, is this effective? And if it is are some sounds better than others (ticking clock, nature etc).

Some reading.

A comparison of auditory and visual distraction effects: behavioral and event-related indices

Infrequent task-irrelevant deviations in the frequency of a tone may distract our attention away from the processing of task-relevant tone duration. The distraction obtained in the auditory paradigm is reflected in prolonged reaction times in duration discrimination and in P3a. The P3a is followed by a late negative component, which may be related to a re-orienting process following distraction (RON, re-orienting negativity). The present study aimed at comparing effects of the auditory and a corresponding visual distraction paradigm. Distraction elicited a deviance-related negativity which revealed a modality-specific distribution. It was followed by P3a (350-ms post-stimulus) and by RON (500-ms post-stimulus). RON did not occur with long-duration visual stimuli indicating a difference in visual and auditory distraction. Moreover, the results suggest that in both tasks irrelevant deviants were detected by modality-specific processes which caused an attention shift.

Can preference for background music mediate the irrelevant sound effect?

Research suggests that listening to background music prior to task performance increases cognitive processes, such as attention and memory, through the mechanism of increasing arousal and positive mood. However, music preference has not been explored with regard to a more common and realistic scenario of concurrent music and cognition, namely the ‘irrelevant sound effect’ (ISE). To examine this, serial recall was tested under quiet, liked and disliked music sound conditions as well as steady-state (repetition of ‘3’) and changing-state speech (random digits 1–9). Results revealed performance to be poorer for both music conditions and the changing-state speech compared to quiet and steady-state speech conditions. The lack of difference between both music conditions suggests that preference does not affect serial recall performance. These findings are discussed within the music and cognition and auditory distraction literatures.

Effects of Music on Cardiovascular Reactivity Among Surgeons

Objective. —To determine the effects of surgeon-selected and experimenter-selected music on performance and autonomic responses of surgeons during a standard laboratory psychological stressor.

Design. —Within-subjects laboratory experiment.

Setting. —Hospital psychophysiology laboratory.

Participants. —A total of 50 male surgeons aged 31 to 61 years, who reported that they typically listen to music during surgery, volunteered for the study.

Main Outcome Measurements. —Cardiac responses, hemodynamic measures, electrodermal autonomic responses, task speed, and accuracy.

Results. —Autonomic reactivity for all physiological measures was significantly less in the surgeon-selected music condition than in the experimenter-selected music condition, which in turn was significantly less than in the no-music control condition. Likewise, speed and accuracy of task performance were significantly better in the surgeon-selected music condition than in the experimenter-selected music condition, which was also significantly better than the no-music control condition.

Conclusion. —Surgeon-selected music was associated with reduced autonomic reactivity and improved performance of a stressful nonsurgical laboratory task in study participants.(JAMA. 1994;272:882-884)

Auditory distraction from low-intensity noise: a review of the consequences for learning and workplace environments

The ‘irrelevant sound effect’ in short-term memory is commonly believed to entail a number of direct consequences for cognitive performance in the office and other workplaces (e.g. S. P. Banbury, S. Tremblay, W. J. Macken, & D. M. Jones, 2001). It may also help to identify what types of sound are most suitable as auditory warning signals. However, the conclusions drawn are based primarily upon evidence from a single task (serial recall) and a single population (young adults). This evidence is reconsidered from the standpoint of different worker populations confronted with common workplace tasks and auditory environments. Recommendations are put forward for factors to be considered when assessing the impact of auditory distraction in the workplace.

A simulator study of the effects of singing on driving performance

This study aimed to investigate how singing while driving affects driver performance. Twenty-one participants completed three trials of a simulated drive concurrently while performing a peripheral detection task (PDT); each trial was conducted either without music, with participants listening to music, or with participants singing along to music. It was hypothesised that driving performance and PDT response times would be impaired, and that driver subjective workload ratings would be higher, when participants were singing to music compared to when there was no music or when participants were listening to music. As expected, singing while driving was rated as more mentally demanding, and resulted in slower and more variable speeds, than driving without music. Listening to music was associated with the slowest speeds overall, and fewer lane excursions than the no music condition. Interestingly, both music conditions were associated with slower speed-adjusted PDT response times and significantly less deviation within the lane than was driving without music. Collectively, results suggest that singing while driving alters driving performance and impairs hazard perception while at the same time increasing subjective mental workload. However, singing while driving does not appear to affect driving performance more than simply listening to music. Further, drivers’ efforts to compensate for the increased mental workload associated with singing and listening to music by slowing down appear to be insufficient, as evidenced by relative increases in PDT response times in these two conditions compared to baseline.

The following has a nice summary of some of the answers I am looking for.

Stress and open-office noise

Forty female clerical workers were randomly assigned to a control condition or to 3-hr exposure to low-intensity noise designed to simulate typical open-office noise levels. The simulated open-office noise elevated workers’ urinary epinephrine levels, but not their norepinephrine or cortisol levels, and it produced behavioral aftereffects (fewer attempts at unsolvable puzzles) indicative of motivational deficits. Participants were also less likely to make ergonomic, postural adjustments in their computer work station while working under noisy, relative to quiet, conditions. Postural invariance is a risk factor for musculoskeletal disorder. Although participants in the noise condition perceived their work setting as significantly noisier than those working under quiet conditions did, the groups did not differ in perceived stress. Potential health consequences of long-term exposure to low-intensity office noise are discussed.

Look around any open-plan office today (especially one full of younger employees) and you’ll see that many workers deal with this problem by wearing ear buds or headphones. Although it might seem that importing one’s own noise wouldn’t be much of a solution, experts say that this approach could be effective on at least one dimension. Part of the reason office noise reduces our motivation is that it’s a factor out of our control, so the act of asserting control over our aural environment may lead us to try harder at our jobs. But does having a constant soundtrack to your day also distract you from the task at hand? That depends on the task. Research shows that under some conditions, music actually improves our performance, while in other situations music makes it worse—sometimes dangerously so.Via


Ritot Smartwatch

Ritot is a smartwatch that projects the time of day, and when connected to your phone, notifications onto the back of your hand. So far I haven’t seen any product from this category that would convince to wear a watch again, but to my eyes this device at least looks attractive.

If you carry an iPhone with you everywhere what purpose does a wearable hold that isn’t already covered by an app.?


Words on screens are not substitutes for words on paper

The differences between page and screen go beyond the simple tactile pleasures of good paper stock. To the human mind, a sequence of pages bound together into a physical object is very different from a flat screen that displays only a single “page” of information at a time. The physical presence of the printed pages, and the ability to flip back and forth through them, turns out to be important to the mind’s ability to navigate written works, particularly lengthy and complicated ones. We quickly develop a mental map of the contents of a printed text, as if its argument or story were a voyage unfolding through space. If you’ve ever picked up a book that you read long ago and discovered that your hands were able to locate a particular passage quickly, you’ve experienced this phenomenon. When we hold a physical publication in our hands, we also hold its contents in our mind.

The spatial memories seem to translate into more immersive reading and stronger comprehension. A recent experiment conducted with young readers in Norway found that, with both expository and narrative works, people who read from a printed page understand a text better than those who read the same material on a screen. The findings are consistent with a series of other studies on the process of reading. “We know from empirical and theoretical research that having a good spatial mental representation of the physical layout of the text supports reading comprehension,” wrote the Norwegian researchers1. They suggested that the ability of print readers to “see as well as tactilely feel the spatial extension and physical dimensions” of an entire text likely played a role in their superior comprehension.
