Cambridge scientist launches free AI-enabled virtual reality platform that transforms users into skilled and confident public speakers<\/p>\n

Presenting in front of an audience is an important and unavoidable part of education and career progression, yet it\u2019s also among the most feared activities, with surveys reporting as high as 80% of students<\/span><\/a> finding this a source of social anxiety.<\/p>\n

Fortunately, a groundbreaking solution has arrived. Thanks to a first-of-its-kind platform developed by Cambridge researcher Dr Chris Macdonald<\/span><\/a>, those suffering from public speaking anxiety can be transformed into skilled and confident speakers. The platform provides tailored course material, a wide range of photorealistic virtual reality (VR) training environments, and support from an AI \u2018coach\u2019.<\/p>\n

As revealed in a recent publication<\/span><\/a> from Macdonald \u2013 Director of the Immersive Technology Lab at Lucy Cavendish College, University of Cambridge \u2013 the platform increases levels of confidence and enjoyment for most users after a single 30-minute session.<\/p>\n

In the most recent trial with students from Cambridge and UCL, it was found that a week of self-guided use was beneficial to 100% of users. The platform helped participants feel more prepared, adaptable, resilient, confident, better able to manage anxiety.<\/p>\n

From 15 March 2025, World Speech Day, anyone in the world can <\/b>freely access the platform<\/b><\/span><\/a>, which is also being <\/b>demoed at the Cambridge Festival<\/b><\/span><\/a> on 29 and 30 March<\/b><\/p>\n

Why do we fear public speaking? And why avoidance isn\u2019t the answer<\/h2>\n

So-called \u2018glossophobia\u2019, fear of public speaking, stems from how we feel about ourselves or specific situations, and kickstarts a physiological response that makes it difficult to perform effectively \u2013 a racing heart, dry mouth, shaky voice and panic \u2013 which has knock-on effects, as Macdonald explains:<\/p>\n

\u201cIt negatively impacts mental health, physical health, academic attainment and career progression. In short, it caps human potential.\u201d<\/p>\n

\u201cPeople tend to avoid speaking opportunities, which maintains or worsens the fear and anxiety. Some seek structured help, but behavioural therapy can come at a high cost or can take over 20 weeks to access and complete.<\/p>\n

\u201cMost people try to overcome the anxiety by practicing. However, the practice environment is often nothing like where they will perform \u2013 it’s usually highly controlled and comfortable like their bedroom, they may be reading from a computer screen, and there is no audience.<\/p>\n

\u201cAs a result, it will feel like a significant step up when they present to even a small group of people \u2013 and a subtle audience gesture can throw them off. I was determined to create a solution that is free and instantly accessible.\u201d<\/p>\n

\u2018Running with weights\u2019 and coached by AI<\/h2>\n

With the new VR platform, a user can experience the sensation of presenting to a wide range of photorealistic audiences.<\/p>\n

What makes Macdonald’s invention unique is that it uses what he calls \u2018overexposure therapy\u2019 where users can train in increasingly more challenging photorealistic situations \u2013 eventually leading to extreme scenarios that the user is unlikely to encounter in their lifetime.<\/p>\n

They might begin by presenting to a small and respectful audience but as they progress, the audience sizes increase and there are more distractions: spectators begin to look disinterested, they walk out, interrupt, take photos, and so on. A user can progress to the point where they can present in a hyper-distracting stadium environment with loud noises, panning stadium lights and 10,000 animated spectators.<\/p>\n

\u201cOverexposure therapy provides the psychological equivalent of running with weights: it builds extra adaptability, grit, strength and resilience. When a user subsequently presents for real, it can feel like a step down. It can feel easy by comparison.\u201d<\/p>\n

\u201cAn added benefit to this gamified approach is that users also really enjoy using the platform. They are curious to see what\u2019s next and they are enjoying the challenge of pushing themselves,\u201d he explains.<\/p>\n

With a background working as a consultant and technical director for leading-edge tech firms, Macdonald knew he could build something realistic and accessible: \u201cWith the latest version of the platform, users have said that the VR environments are so realistic it\u2019s like being teleported to a different place.\u201d<\/p>\n

To help users improve their presentations, an AI \u2018coach\u2019 has been embedded into the platform to provide feedback. Macdonald trained it using examples of the top 100 speeches of all time. It was a little harsh to begin with, as Macdonald explains:<\/p>\n

\u201cThe coach was initially so effective in its critical comparison that it really demotivated the user. It was as though every word was crossed out with a red pen and the user had failed,\u201d he says. \u201cI had to dial it back. It now prioritises the areas that have the biggest impact and it gives more encouraging guidance. It empowers the speaker to develop their own unique style.\u201d<\/p>\n

Built for real people with limited budgets<\/h2>\n

Macdonald’s aim was for the platform to be accessible to all and so he developed a method that converts smartphones into VR headsets: \u201cOnly 5% of UK households have a VR headset but 99% have smartphones. And while VR headsets can cost thousands, a device mount costs around \u00a315. An old smartphone inserted into a low-cost device mount will provide the same content and the same experience.\u201d<\/p>\n

A first-of-its-kind, dual-compatible VR player ensures it works on both Android and iOS. \u201cNot only is this the first time that this treatment is available for free worldwide, it\u2019s also the first time it is accessible via multiple devices and multiple operating systems.\u201d<\/p>\n

During development, the platform hosted over 50,000 practice presentations from remote beta users. To further stress test the platform, Macdonald took the lab on tour which included exhibits at the leading science and technology events as well as events at a local market, library, community centre, church, and even someone\u2019s living room. On 29 and 30 March 2025, he’ll be demoing the platform at the Cambridge Festival<\/span><\/a>.<\/p>\n

\u201cI wanted to build something that is not only highly effective but that can and will be used by those who need it the most.\u201d<\/p>\n

\u201cWorking closely with end users has been crucial to making sure the platform \u2018works in the wild\u2019 and becomes increasingly more effective. Through constant public engagement, we can remain deeply grounded in public service.\u201d<\/p>\n

\u201cAt one demo in Cambridge, we had over a thousand people trying it out. One woman was visibly very emotional. She said to me that she would have had the confidence to become a teacher if this had been around when she was younger.\u201d<\/p>\n

\u201cIt really validated the idea that the platform can expand career horizons.\u201d<\/p>\n

It is very promising to see how effective the platform is given that I am already working on the next round of updates.<\/p>\n

In addition to the range of presentation-style audiences, he has started adding more specialised environments and challenges, such as reading a teleprompter in a virtual TV studio or responding to questions in a job or radio interview. Beyond the main platform that is now freely available<\/span><\/a>, he has created an app for healthcare providers, and is collaborating with organisations that seek to support specific groups such as children who stammer.<\/p>\n

\u201cThe goal is to create more targeted treatment options for those who need it the most. I am currently seeking funding to facilitate this.\u201d<\/p>\n

Dr Chris Macdonald<\/b><\/span><\/a> established the multi-award-winning Immersive Technology Lab<\/b><\/span><\/a> to investigate the transformative potential of emerging technologies for education and healthcare. He is a Fellow at Lucy Cavendish College, University of Cambridge.<\/p>\n
