This assistive technology project is a continuation of the STEM course. We got into groups of 4 or 5 -- in my case, a group of 5 with Varsha, Anshu, Harshil and Jackson -- to build a device for people with autism experiencing sensory overload. We started with brainstorming ideas, writing a grant to buy materials, prototyping multiple designs, and finally, testing our final prototype. In the last week of school in May, we usually have our AT fair where we present our projects to the community.
AuSense
Many individuals with autism experience sensory overload – an overwhelming response to lights, sounds, textures, and other environmental stimuli. It is detrimental to their mental health and their capabilities due to how a sensory overload episode can diminish one’s brain functionality and restrict their freedom to only areas in which there is no provocative stimuli. Different people have varying sensory thresholds, which influence their susceptibility to the episodes.
Construct a device that enables users to input their personal sensory thresholds for light, heart rate, and sound. The device will continuously monitor these environmental and physiological inputs and alert the user when conditions approach levels that may trigger a sensory overload episode.
Design Approach
Background and Market Research
Prototypes
We began by identifying the most common sensory triggers—light, sound, and elevated heart rate—and understanding how they can lead to overstimulation and distress. We then made three prototypes that integrate three key sensors: a light sensor, a sound sensor, and an Emotibit which can return heart rate. The device connects to a custom-built mobile app, allowing users or caregivers to input personalized threshold values for each parameter based on their unique sensitivities. Throughout development, we prioritized user feedback design, ensuring the device is subtle, comfortable, and easy to operate.
