The Senzo Nightlight is a nightlight that will stream from one end of the wall to the next. The nightlight is built so that no matter which wall someone is standing next to, they are able to see with a simple touch of the light. The nightlight has a power source so that batteries are not wasted throughout the day when the light is not being used. The pressure sensors in the nightlight are strung through its entire shell, creating an easy to use design. The design was created with the thought of someone walking down a dark hallway. If someone cannot see walking down a dark hallway, it is sometimes easier for him or her to use a hand or fingertip to distinguish where a wall is in reference to the walkway. Rather than having to touch a wall to identify objects or hallways in the dark, this light will immediately illuminate the walkway for an easier late-night walk to the kitchen without stumbling over any annoying rugs or furniture. The light has three modes. The first mode is standby which is when the light is waiting to be touched, the second is the on mode which lights the entire walkway up without having to constantly touch the light, and the last mode is the E mode. In E mode, if the power in the house goes out, the light immediately illuminates.

This design has to do with Human-Centered Design because its sole purpose is to help a user in the absence of light. The product was created for a direct touch from the user and also includes settings that can be easily manipulated by the user. The light contains automatic feedback in that a touch will turn the light on depending on the setting the device is locked into.

People needed to create this device:

Electrician- Electrical circuits and components

Expert in sensory touch

Testers- All ages and heights to ensure the use of the product

Home Designer- To make the aesthetics and sensors appropriate- also to allow the right amount of light.


Although I believe this to be a simple design, it is also a very clever design. This light could help any children, adults with cluttered homes, and maybe even construction workers working in dark rooms or hallways. I would enjoy working on a design such as this after the Human-Centered Computing program.
