Figure 1: Traffic Lights (Source: X-PERT GENERAL SERVICES, LLC., 2012)

I’ll be delivering three (3) examples of consistency, the specific principles of consistency will range from aesthetic-consistency to functional-consistency. To begin, I’ll be using the example of the traffic light. The traffic light is an example for the functional consistency principle, as we are aware of the meaning behind what the traffic light is there for. The traffic light is an object in which it indicates to vehicles whilst on the road when to stop, go or slow-down when approaching joint roads that clash. How the traffic lights are controlled, as explained from the Brisbane City Council’s (2008) ‘Roads & Traffic Fact Sheet’; “Traffic lights are controlled by a local computer at each intersection and is networked for remote access by traffic engineers or officers […]”.

Figure 2: The Prisoners & The Light Switch Riddle (Source: Zazenlife.com, 2012)

The second (2nd) example is that of the light switch. The light switch is a little switch within a room that turns on the light, it is associated with the aesthetic-consistency principle. Reason being is because when we know of the appearance of a light switch and the placement within a room. The Fun Times Guide (2012) states the placement of a light switch “You should place all light switches on the latch side of a door, not the hinge side. This makes it easier to access the lights as you walk in or out of a room.” When we enter a dark room, we tend to feel around the side of a doorway for a light switch, we know aesthetically what the light switch would ‘feel’ like, ‘look’ like and what its purpose is.

The final example is extracted from Lidwell, Holden & Butler’s (2003) ‘Universal Principles in Design’, and the example highlighted is the internal-consistent ‘Signs within a park’. Signs within a park are consistent with each other as they show the same purpose, to indicate to the visitor where a certain place is, what to look out for, where to go and so on. All of the information is confined within the same area, thus they’re connected with each other. Same can be said about signs within a ‘zoo’ or a ‘golf course’, each have the same criteria and purpose, delivering the same information only in a new setting.

Consistency Analysis (Item 1 / Q1 Summary)

October 29, 2012 Leave a comment

Lidwell, Holden & Butler (2003) briefly explain the meaning behind the systems of consistency and how they’re connected with each other in similar ways. The four (4) systems or principles of consistency are; aesthetic, functional, internal and external.

Figure 1: Yellow Light: Knowing When to Go and When to Stop (Source: Cimarron Claims Service, Inc., 2012)

Each of the principles are defined, starting with aesthetic-consistency; it’s the appearance and style that delivers an emotional attachment with an individual’s product, for example, hood ornaments on a vehicle to identify if it’s popular or not (e.g., Mercedes-Benz). Same can be said about company logos. Functional-consistency is the “meaning and action” behind consistency, an example Lidwell, Holden & Butler use, is traffic lights, how the colour ‘yellow’ indicates to a vehicle to slow-down before the traffic light shows red, meaning to ‘stop’. Internal-consistency is consistency within a system, an example the authors use is signs within a park that a consistent with each other; same with golf-course signs, guiding the individual to each hole. Finally, external-consistency is the consistent with other element in the environment, for example, alarms bring warning but for each alarm, it has a different meaning, there’s a significant difference between the alarm sound from an ‘ambulance’ than a ‘police car’.

For a better demonstration of consistency, Simon (2010) uses the example of a feature film. Aesthetic consistency is used within the feature film project; the production costs and what brand of equipment/software will better suit making the project look fantastic. Simon goes on to explain “Having such a high grade product for the narrative driver is a blessing and a curse.” He continues to weigh the pros and cons. Pro: when having a successful budget to produce the film, it will show how good the quality of the brand the director is using is. Con: Using such brand may produce obstacles for the other platforms. Another fine example is from the Australian Government (2011) and their demonstration of consistent work habits; “Consistency regarding appropriate attitude, commitment, and performance at work is important in any workplace.” One (1) example of consistency within work is using a pin-up or whiteboard in the work area for all relevant work information.

Aesthetic-Usability Effect Examples (Item 1&2 / Q2 Examples)

Figure 1: Nokia 6500 Slide Mobile Phone (Source: Get Price, n.d.)

I’ll be exploring three (3) examples that use the Aesthetic-Usability Effect. Two (2) examples are discussed in Lidwell, Holden & Butler’s (2003) article on ‘Aesthetic-Usability Effect‘, firstly starting with the Nokia cellphones. The authors discuss that Nokia included more communication features with their phones after being one of the first to realize the potential these new features would have on the cellphones. Problems that would decrease the risk in sales would include having to charge the phone constantly, carry it around everywhere and the signal would drop. “Aesthetic elements like color covers and customizable rings are more than ornaments, the aesthetic elements create a positive relationship with users…”. (Lidwell, Holden & Butler, 2003)

Figure 2: TiVo, Dead or Alive (Source: The Sydney Morning Herald, 2011)

The second (2nd) example from this extract is ‘TiVo’. What is TiVo? “TiVo combines instant access and amazing control […] Enjoy being able to record, pause and rewind live TV”. (Hybrid, 2012) Simply put; the TiVo uses aesthetic design to show how advanced television recording has become, and through advertisements, shows how easy it is to use the TiVo. This is a rather significant improvement from the VCR’s recording system. Some of the improvements Lidwell, Holden & Butler (2003) discuss “TiVo is setting a new bar for recording convenience and usability. TiVo’s intelligent and automated recording features, simple navigation through attractive on-screen menus…”.

Figure 3: PC or Mac (Source: Intel Corporation, 2009)

The final example is the Mac. There’s been an everlasting debate on whether a Mac is better than a PC. Extracted from the Intel Corporation (2009) website page ‘PC vs Mac: The Big Debate’ they state the differences in components and which piece of technology is more advanced than the other. PC has been highlighted as having more flexible and better specs, as the following extract from the site explains “Most PCs have anywhere from 2GB to 8GB of RAM in laptops and desktops, while Macs usually have only 1GB to 4GB.” Mac’s however are advertised as easy-to-use machines, as stated from Kahney’s (2002) article “Apple’s design aesthetic is so strong, one college professor gets his students to design new hardware specifically for Apple”.

Aesthetic-Usability Effect Analysis (Item 1 / Q1 Summary)

October 18, 2012 Leave a comment

An extract from their article, Lidwell, Holden & Butler (2003) explains the effects in Aesthetic-Usability and how the general public in today’s society react to Aesthetic designs, how they present possibly difficult objects as ‘easier to use’ rather than the negatives.

A brief description extracted from Mark Boulton’s (2005) journal online describes Aesthetic-Usability Effect as “a condition whereby users perceive more aesthetically pleasing designs to be easier to use than less aesthetically pleasing designs.”

Figure 1: Computer Skills (Source: University of New South Wales, 2012)

Further into Lidwell, Holden & Butler’s extract, they go into depth with aesthetic designs and highlight how they will always be presented as easier to use, even though they are or are not easier to use in the first place. A prime example within the text “…in a study of how people use computers, researches found that early impressions influenced long-term attitudes about their quality and use.”  (Lidwell, Holden & Butler, 2003)

Aesthetics in our life-world play a crucial role in the way design is seen and used today. Here is a brief example of aesthetic-usability and its design; the ‘in-vehicle navigational display’. Lavie, Oron-Gilard & Meyer (2011) from the Department of Industrial Engineering and Management have conducted studies on the in-vehicle navigational display. The first (1st) study was on the aesthetic scale to “accommodate evaluations of map displays”. The second (2nd) study on the map displays and how much they present on-screen. So it’s with these key factors that people care for the most with in-vehicle navigational displays.

Towers (2010) has stated negatively towards the subject matter of Aesthetic-Usability with “The aesthetics of a product have far reaching consequences”. Further into her article, she explains in dot point what aesthetic design of a product can cause to the general public, like for example; a product may be ‘nicely’ presented but lacks the proper components, but because the product is more appealing, it could lead to the user having positive feelings to it, and thus could lead to a large majority giving the product positive reviews, which would increase sales.
