Machine Learning Supported Assisted Travel

出差或求学对许多人来说是一个巨大的挑战。有100万16-24岁的年轻人患有焦虑症，350万人患有感觉加工障碍，70万人患有自闭症。这些人中的许多人由于在参加工作和教育的旅途中所面临的困难，很难完全融入社会。BOM已经开发了一款应用程序--隐藏王国，它使用空间化的音频和想象的三维世界，沉浸式的王国被‘映射’到旅行者的旅程中，当他们在上班、上学或大学的通勤途中经历焦虑或痛苦时，为他们提供支持。对这款应用的测试表明，这种方法存在局限性，但这是一个重要的机会。在应用程序中配置行程所需的初始开销限制了应用程序的使用。我们的项目旨在通过探索使用手机、智能手表或健身跟踪器数据来推断情绪状态的可能性来减少这一开销。移动设备能够从GPS、加速计或光体积描记(PPG)传感器等传感器捕获广泛的数据，这些传感器可以用来确定旅行者的步态(步行模式)、旅行方向或心率。机器学习方法可以用来识别这些数据中表明焦虑或痛苦的模式。一旦识别出，这款应用程序就可以提供相关内容，比如友好的动物伴侣出现并提供帮助，邀请在他们的手机屏幕上观看隐藏王国的风景，或者播放治疗音频内容。目标是创建一个应用程序，对用户在旅行期间的体验做出敏感和适当的响应，无论是计划的还是其他的。

Travel for work or education is a significant challenge for many people. There are one million young people aged 16 - 24 with anxiety, 3.5 million people with Sensory Processing Disorder and 700,000 who are autistic. Many of these people struggle to fully engage with society due to the difficulties they face on the journeys they must undertake to participate in work and education. BOM has created an app Hidden Kingdoms that uses spatialiszed audio and imaginary three dimensional worlds, where immersive Kingdoms 'mapped' onto travellers' journeys, support them as they experience anxiety or distress during commutes to work, school or college.Testing of the app has revealed a limitation to the approach, and a significant opportunity. The initial overhead required to configure journeys in the app is an inhibitor to app use. Our project aims to reduce this overhead by exploring the possibility of using mobile phone, smartwatch or fitness tracker data to infer emotional state. Mobile devices are capable of capturing a wide range of data from sensors such as GPS, accelerometer or photoplethysmography (PPG) sensors that can be used to determine the traveller's gait (pattern of walking), direction of travel or heart rate. Machine learning approaches can be used to identify patterns in this data that indicate anxiety or distress.Once identified the app can deliver relevant content, such as a friendly animal companion appearing and offering help, an invitation to view the Hidden Kingdom landscape on their phone screen, or therapeutic audio content being played back. The objective is to create an application that responds sensitively and appropriately to users' experience during their journeys, planned or otherwise.
