The PowerPoint Collection

A collection of blogposts about PowerPoint.

Corrupting Evidence (Feb 2005) 
Edward Tufte is writing a book called Beautiful Evidence, about the proper and improper use of modern rhetorical media, such as PowerPoint.

What Exactly is PowerPoint For? (March 2006)
Microsoft is making concerted efforts to improve their own use of PowerPoint, and to encourage others to use it better. Bill Gates spoke without slides in his keynote speech at Mix06.

Beyond Bullet Points (May 2006)
Some of my friends at Microsoft are excited about Cliff Atkinson and his "new" presentation style, based on the work of psychology professor Richard E. Mayer.

Who's the Dick in the Wine Bar (May 2006)
If you are accustomed to traditional PowerPoint, beware. You may find these videos disturbing.

PowerPoint Slides (Nov 2006)
It is not Microsoft's fault if the Pentagon makes inappropriate use of the available tools. Loads of stupid documents have been written in Word, and loads of bad accounts produced in Excel. But it is PowerPoint gets most of the criticism.

Blame PowerPoint (Oct 2009)
If different groups or communities use PowerPoint differently, there may be many different PowerPoints-in-use corresponding to a single PowerPoint-as-built.

Visualizing Complexity (April 2010)
Lot of people have been mocking a diagram that attempts to visualize the complexity of the situation in Afghanistan using system dynamics, rendered as a PowerPoint slide. (Many people have chosen to blame PowerPoint for the complexity of this diagram.) See also Understanding Complexity (July 2010)

Visual Cliché in Architectural Discourse (Nov 2010)
The visual language of architectural discourse, from enterprise to software, is surprisingly weak. Many diagrams look as if they may have started as meaningful sentences, but they have been transformed into diagrams by discarding most of the words and putting the remaining words into coloured shapes, arranged artistically on the slide.

The Power of Twitter

Let's suppose I want to find an intelligent review of a film.

If I just put the name of the film into Google, I will get endless repetitions of the synopsis, together with details of cinemas showing the film, or places to buy/download.

In my post You don't have to be smart to search here ... but it helps (Nov 2008), I outlined one possible trick. If you put the name of the film together with a random cultural icon (my example was Lacan), you will get reviews of the film that name-drop the icon. That immediately filters out all the standard cinema listings. However, you might need to try a number of different cultural icons until you strike lucky.

A second option is to subscribe to good magazines. When I watched the film Anomalisa, I didn't immediately make the connection with Schopenhauer. The connection was made for me by a fascinating review by Zadie Smith in the New York Review of Books.

Once you know that such a connection exists, you can use Google to find it. But Google won't make that connection for you - unless sufficient numbers of other people have already made that connection.

So here's a third option. Twitter allows you to have a list of intelligent film critics, and intelligent magazines containing intelligent film reviews. Either you decide for yourself what counts as intelligent, or you adopt someone else's list. Then you can search through the list for seriously intelligent reviews of the latest film. You can't do anything quite like this with Google.

When you search for something, Google can give you page after page of practically identical material - for example, hundreds of newspapers all repeating the same press release. What one really wants is a search engine that works out which page represents the original source, which pages represent replications with no added content or value, and which pages offer additional commentary and interpretation. It is possible that Twitter, with its conversational structure, may be closer to providing this kind of navigation. But only if the platform can achieve reasonable commercial viability without being polluted.

The Force of Goole

When people talk about Internet Binging, they aren't talking about using the world's fourth most popular internet search engine. According to @ruskin147's BBC Radio Four documentary The Force of Google this evening, people don't even use the generic phrase "searching the internet". They use the word "Google". I think I heard someone say that the word is now more popular than the word "eggs".

Rory discussed several ways that hard-boiled Google poaches Internet business, while scrambling our brains.

1.  Business is dependent on the caprice of Google ranking. Rory talks to the owner of a fly fishing company, which gets a significant proportion of his business via Google. When Google changed its algorithm in 2013, his webpage dropped from page one to page seven - almost equivalent to a commercial death penalty. Then inexplicably it climbed back again - the death penalty reprieved. Readers with long memories will remember the story of BMW (Feb 2006), which was banished from Google for three days in 2006.
2. In trying to be as helpful as possible to searchers, Google sometimes fails to respect the interests of other information providers. For example, if you search for hotels in Bury, you get Google's automatically curated list before you get lists from rival platforms such as TripAdvisor and Yelp. 

3. In the past, there has been some evidence that Google is biased towards controversial new technologies, perhaps because the technology vendors spend more on advertising than the technology sceptics. I have noted this apparent bias in relation to Biometrics (Nov 2003) and RFID (Nov 2005). Google now seems to have made some progress on this issue - Rory looked up "fracking" and got a more even-handed view from Google than from Bing.

4. Even without any obvious commercial or political agenda on Google's part, it is easy to see how Google's results could appear to show a lack of balance. Note for example the recent controversy about Unprofessional Hair. There have also been suggestions that Google page ranking could influence the public perception of politicians and thus sway elections.

5. One of the most dangerous aspects of the Google phenomenon is the widespread illusion that Google gives you Objective Truth. Rory talks to Ben Gomes, who is described as Google's Guru of Search, who talks about the Quest for the Perfect Search.

"The perfect search is giving you what you were looking for. Not just the words you typed - but what you were actually looking for."

The programme gave the impression that Google is converging on the Perfect Search. Rory himself says he generally finds what he is looking for. My own experience is that it sometimes requires a fair amount of ingenuity to find stuff, especially interesting and original stuff. See my posts You don't have to be smart to search here ... but it helps (Nov 2008) and Thinking with the Majority (March 2009). See also The Power of Twitter (April 2016).

Wondering about the deliberate spelling mistake in the title of this post? I wanted to pay tribute to a listing from @brightonargus.
Which reminded me of the original Argus Panoptes, the giant who would be the mythical ancestor of Google. And also the ARGUS-IS system, a secret rival to Google's Street View.  Even Argus may have flawed vision sometimes.

Wikipedia: Argus Panoptes, ARGUS-IS.

From Networked BI to Collaborative BI

Back in September 2005, I commented on some material by MicroStrategy identifying Five Types of Business Intelligence. I arranged these five types into a 2x2 matrix, and commented on the fact that the top right quadrant was then empty. 

The Cloud BI and analytics vendor Birst has now produced a similar matrix to explain what it is calling Networked BI, placing it in the top right quadrant. Gartner has been talking about Mode 1 (conventional) and Mode 2 (self-service) approaches to BI, so Birst is calling this Mode 3.

While there are some important technological advances and enablers in the Mode 3 quadrant, I also see it as a move towards Collaborative BI, which is about the collective ability of the organization to design experiments, to generate analytical insight, to interpret results, and to mobilize action and improvement. This means not only sharing the data, but also sharing the insight and the actioning of the insight. Thus we are not only driving data and analytics to the edge of the organization, but also developing the collective intelligence of the organization to use data and analytics in an agile yet joined-up way.

I first mentioned Collaborative BI on my blog during 2005, and discussed it further in my article for the CBDI Journal in October 2005. The concept started to gather momentum a few years later, thanks to Gartner, which predicted the development of collaborative decision-making in 2009, as well as some interesting work by Wayne Eckerson. Also around this time, there were some promising developments by a few BI vendors, including arcplan and TIBCO. But internet searches for the concept are dominated by material between 2009 and 2012, and things seem to have gone quiet recently.

Artificial Belligerence

Back in the last century, when I was a postgraduate student in the Department of Computing and Control at Imperial College, some members of the department were involved in building an interactive exhibit for the Science Museum next door.

As I recall, the exhibit was designed accept free text from members of the public, and would produce semi-intelligent responses, partly based on the users' input.

Anticipating that young visitors might wish to trick the software into repeating rude words, an obscenity filter was programmed into the software. When some of my fellow students managed to hack into the obscenity file, they were taken aback by the sheer quantity and obscurity of the vocabulary that the academic staff (including some innocent-looking female lecturers) were able to blacklist.

The chatbot recently launched onto Twitter and other social media platforms by Microsoft appears to be a more sophisticated version of that exhibit at the Science Museum so many years ago. But without the precautions.

Within 24 hours, following a series of highly offensive tweets, the chatbot (known as Tay) was taken down. Many of the offensive tweets have been deleted.

Predictive and Real-Time Analytics

I shall be chairing the @UNICOMSeminars Data Analytics conference next week. Exploring the Business Value of Predictive and Real-Time Analytics (London, 2 December 2015)

A lot of the obvious applications of real-time analytics are in fraud detection and predictive maintenance. I shall be talking about some of the things I’ve been doing recently in the retail and consumer sector, using rich consumer data to drive real-time personalized engagement with the consumer across multiple touchpoints. We have been exploring ways to combine real-time analysis of the consumer’s current state (e.g. current location, what products they are currently looking at, readiness to buy, etc.) with a rich understanding of what one might call the consumer’s “purchasing genes” – for example, do they like to spend a long time reviewing alternative products before purchasing, do they like to wait for a special offer or voucher before buying, or on the other hand do they like to be the first in their social network to have a given product. This is a lot more complex than simply putting them into a fixed number of “consumer segments”.

Based on this analysis, it is possible to select an appropriate “next action” – for example, selecting the appropriate banner to display to the consumer when visiting the website, or the right topic of conversation for a human customer services agent.

Thus predictive analytics are helping retail as it moves from omnichannel commerce (which joins up the buying transaction between the online and the physical world) to omnichannel engagement (which joins up all aspect of the relationship with the consumer).

Omnichannel Commerce
(Systems of Record)

joins up the buying transaction between the online and the physical world
Omnichannel Marketing
(Systems of Engagement)

joins up all aspects of the relationship with the consumer

Given the large volumes of data involved, and the reliance on legacy systems to produce and process the data, we are not yet seeing this analysis being completely done in real-time. However, there are some critical factors that have to be done in real-time. For example, as soon as the consumer buys something, our clients want to stop trying to sell it, and move to a post-sales scenario. (In comparison, even the great Google is still showing me advertisements based on what I was browsing three weeks ago. Fail!)

Over the next couple of years, as the technology gets better, the data scientists get even smarter, and the marketing people get more sophisticated, we may expect an increasing proportion of the analysis to be done in real-time, using machine learning as well as more sophisticated analytics tools.

Towards the Internet of Underthings

#WearableTech #InternetOfThings Once upon a time, the wires in an undergarment merely provided structural support. Now, people may have all sorts of wires and wireless devices hidden under their clothing. Here are some interesting examples.

  • The Foxleaf Bra delivers cancer-fighting drugs through the wearer's skin.
  • The @tweetingbra reminds women to examine themselves. (?)
  • The Lumo Lift helps improve posture through app-enabled coaching.
  • Various manufacturers (including Clothing+, OMsignal and SmartLife) produce health vests and sportswear packed with monitors to track your heart rate, breathing rate and the amount of calories you've burnt.

We are now encouraged to account for everything we do: footsteps, heartbeats, posture. Until recently this kind of micro-attention to oneself was regarded as slightly obsessional, nowadays it seems to be perfectly normal. And of course these data are collected, and sent to the cloud, and turned into someone else's big data. (Good luck with those privacy settings, by the way.)

If a device is classed as a medical device, it will be subject to various forms of accreditation and regulation. For this reason, many device makers will be careful to avoid any specific medical claims, but devices that offer some health advice are considered a borderline area.

Another borderline area is hi-tech underpants that protect men from the evil rays allegedly produced by all those wireless devices. Especially the radiation from mobile phones. (Including the Bluetooth that links your underwear to your smartphone.) One brand of underpants that claims to use a mesh of pure silver to create a Faraday cage around the genitals has been banned by the UK Advertising Standards Authority from making any medical claims.

Or maybe you could just switch the whole lot off.

Weaving in three dimensions

A garment is essentially a three-dimensional object. And yet the most common way of producing garments is from flat sheets of material - for example cloth or leather - that can be cut into pieces and then sewn into items of clothing. So we have a complex interaction between two patterns - the weaving pattern on the cloth and the cutting pattern for the tailor.

Some clothing designers have started to experiment with 3D printers, producing amazing fashion dresses and accessories.

Designer: Danit Peleg

Designers: Francis Bitonti and Michael Schmidt

For more examples, check out designers like Continuum Fashion.

But these costumes are mostly monochrome, and made from artificial materials such as nylon. Great for catwalk or party, or even a fashionable beach, but not exactly everyday wear. So instead of 3D printing, what about 3D weaving, using traditional materials? Here's something in linen.

Designer: Chen-Hsiang Hu
The industrial designer Oluwaseyi Sosanya has developed a new 3D weaving method, which allows not only the exact shape and size of the garment to be varied to the exact requirements of the wearer, but also the qualities of the woven fabric. He has been experimenting with footwear, where the density of the sole can vary from one part of the foot to another.

"With this [weaving system] you can pre-programme the density. At the ball of your foot, you may want a denser material. Right at the arch of your foot, you might want a softer material. At the heel, you might want a denser material. You can have that in one go."

Furthermore, Sosanya's system allows the footwear to be customized to the wearer's requirements, from sports to orthopaedics.
"Your foot is completely different to my foot,” said Sosanya. “We walk different, our cadence is different. All of these things are factors which play into the performance of our footwear. Now with 3D printing, you can scan your foot and you can scan an insole or even a whole sole or the whole shoe at some point. The designer and the chiropodist can say that you need to remove some material here and you can correct your walking. You have all of these opportunities now where you can do customisation around footwear." 

Of course, there is some history here. According to Wikipedia, perforated paper tapes were first used to control looms around 1725, but this technology did not become widespread until Jacquard switched to punched cards around 1801.

Source: Wikipedia

And according to the New Testament, Jesus wore a seamless robe for his crucifixion. One source (repeated around the internet, and now here) argues that this indicates an early Palestinian form of 3D weaving.
"Completely seamless garments, like the one Jesus wore, were unique to Palestine. They were woven on upright looms that used two sets of vertical warp threads, one at the front and one at the back of a crossbar. The weaver would alternate his shuttle, which carried the horizontal weft thread, from the front part of the web to the back, 'thus creating a cylindric piece of fabric,' says one reference work. A seamless tunic would likely have been a rare possession, and the soldiers considered it a desirable one." (Watchtower, 1 July 2009 p22)

If we combine these ancient and modern innovations, we can conceive of a very sophisticated form of personalization, in which the pattern on the cloth can be perfectly aligned with the cut of the garment, regardless of the size and shape of the wearer, without wasting material. And the material can be reinforced at elbows and shoulders. And the whole garment can be woven while you wait. No more child tailors in Far Eastern sweatshops then.
