Containers that enable blind people to determine the level of contained hot water

Abstract:
To determine the water level in a container, people who are blind use electronic aids or the sound and weight of poured water. In this work, three non-powered containers were designed to assist blind people in detecting the level of hot water in a container. Their effectiveness was evaluated and compared with that of an unaugmented control container. The capacities of the designed containers and the control container were 800 mℓ. The results reveal that, when blind participants poured 400 mℓ of water into the containers, they could determine the volume of water in two of the designed containers with smaller average errors (13.03 mℓ and 26.88 mℓ) than in the control container (36.60 mℓ). One of the designs also attracted positive scores for all satisfaction-related variables and was improved in response to feedback on its prototypes.

Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
