The Fox Report Barry Fox’s technology column From virtual reality to virtue signalling I AAPA , the self-styled ‘Global Association for the Attractions Industry’ (don’t ask me how the acronym derives), recently came to the ExCel Conference Centre in Docklands near London City Airport. (See: www. iaapa.org/expos/iaapa-expo-europe for more details.) Founded in 1918, IAAPA is – in plainer English – the trade body for companies involved in the big business behind the world’s amusement parks, theme parks, attractions, water parks, resorts, family entertainment centres, zoos, aquariums, science centres, museums, cruise lines, manufacturers and their suppliers. ExCel is a huge cluster of giant, utilitarian exhibition halls, now nicely accessible by the new Elizabeth tube line as well as the driverless Docklands Light Railway. If you’ve ever watched the movie, The Long Good Friday, the transformed ex-docks area round ExCel is what Bob Hoskins cleverly foresaw before he was scarily disappeared in the back of a cab. I went along looking for new electronic technology that might make a day at a ‘park’ more fun… or more scary. What I came away with was an overriding impression, best summed up by a bunch of pictures. In a nutshell, the Attractions industry sees the next 1555F IP68 sealed flanged enclosures big thing as virtual reality (VR) and augmented reality (AR). Although only a few couch potatoes will don headsets to watch movies (which is what so absolutely predictably kills 3DTV and cinema 3D every time it is re-invented) people who go to theme parks may well be up for wearing one. Put simply, the theme park industry is over-layering VR/AR tech on conventional park rides, games and experiences – see the pictures below. Most speak for themselves, except the one which shows the tribute to the Queen – who had just died – electronically plastered all over ExCel’s front entrance.

Online ‘safety’ The UK will be one of the first countries in the world to pass laws aimed at making online users safer, while preserving freedom of expression. The Online Safety Bill – due 2023 – will introduce rules for sites and apps such as social media, search engines and messaging platforms, along with pretty much every service used to share content online. Few people will argue with the basic idea and good intention, providing it is handled well. So, who will handle it? A safe pair of hands? Ofcom has the gig, and says it will, ‘within the first 100 days,’ have a draft Code of Practice for the industry and then ‘consult publicly’ ahead of going live in 2024. Ofcom will have ‘a range of investigation and enforcement powers’, ‘build on the expertise we have already brought in from the technology industry’, ‘work with other regulators… to ensure a joined-up approach’ and ‘ensure the tech companies are more transparent and can be held to account for their actions.’ Says Ofcom: ‘The Bill does not give Ofcom powers to moderate or respond to individual’s complaints about individual pieces of content…the sheer volume of online content would make that impractical.’ Fair enough, but it means Ofcom will have to rely on unspecified other bodies to steer enforcement. This is exactly the way it works for controlling telecoms service providers; or, frankly, doesn’t work. As I put on record in Practical Electronics in October 2022, Ofcom’s Practical Electronics | December | 2022 consumer complaints process is a pantomime farce which can trap anyone daring to complain about a telecoms service provider in a circular loop – with Ofcom refusing to accept individual complaints and referring people to the Telecoms Ombudsman and Information Commissioner (ICO), while the Ombudsman refers complaints back to Ofcom and to the ICO, while the ICO refers people back to the Ombudsman; and all the while Ofcom boasts that the number of complaints is falling, as people doubtless just get weary of life and give up on complaining. Just for the heck of it, I sent Dame Melanie Dawes, Ofcom’s Chief Executive, a personally addressed letter, suggesting that if she were interested in the way Ofcom’s own guide literature is muddled and how real-world complaints can get loop-locked, I would show her some carefully documented examples. My letter mysteriously failed to reach her office. Ofcom then asked for a resend but failed to provide a direct email address for her office or personal assistant. So, fool that I am, I travelled to London and hand-delivered a copy to Ofcom’s HQ in Southwark, along with hard copy of the PE article. I’ve heard nothing from Dame Dawes, but a member of the Ofcom’s Consumer Contact Team has been delegated to recommend seeking independent legal advice and using Ofcom’s complaints system to complain about Ofcom. They just don’t get it, do they? And it surely hangs a question mark over how Ofcom will now handle the extra task of controlling Online Safety. …and finally I collect examples of how official bodies are often run by officials who clearly do not use the IT they are expecting consumers to use – or have utter contempt for consumers. The latest, and one of the best yet examples, is to be found on Camden Council’s Planning Search site. I suggest you look quickly before they finally wake up to the absurdity of the search process, which has so far obstructed anyone trying to trace a planning application for a building, by not unreasonably expecting it to show up under its street address, see: https://bit.ly/pe-dec22-daft Note the instruction that to search by site address, ‘you can enter a house number and street name or post code’. So far, so good. But you also need to know that the ‘Site address is sensitive to punctuation and spaces. Do not use commas or the word London.’ Hmmm. Not very user-friendly. But let it pass. But here’s the killer-driller: if you want to get a result from your search you must, ‘use % when typing addresses; eg, %1%Camden%Road%.’ Discovering this Boolean obstacle to essential everyday planning business makes yet another of those ‘couldn’t make it up’ moments.
