Background:
Falls are problematic in the older adult population (Ganz et al, 2007). The impact in quality of life of fallers and the economic burden of falls are a major health problem in our society. The timely detection of fall occurrences is crucial to maximizing recovery potential post fall. This means that fall detection systems that are researched in terms of usability and satisfaction are crucial in minimizing the effects of a fall.

Method:
FATE (Fall detector for the elder) is a fall detection system that was evaluated in terms of usability. The FATE system comprises of an accelerometer sensor worn on the waist that detects falls automatically. A crossover design was adopted in carrying out the study.

Results:
The results indicate that the FATE system is deemed “acceptable” in terms of usability. It was found to be neither satisfactory nor dissatisfactory in terms of satisfaction. However, participants were very satisfied in terms of service use and delivery they received.

Conclusion:
The results of the study highlight the need for user centered design and consultation with the older adult (end user) and healthcare professionals to ascertain what they want from a fall detection system and what they would comply with using on a day to day basis.

Application to Practice:
The results of the study highlight the need for user centered design that includes input from healthcare professionals. It aids in the timely detection of falls, once the system is deemed to be satisfactory in terms of usability.
