The research objective was to gather data on the ability of older populations to operate digital cameras having a graphics display interface and a motor control in terms of sensory, motoric and cognitive suitability as well as the interface language (English) and gender oriented differences.
The research population consisted of 40 participants from 2 experiment groups: The adult group aged 55-64, and the control group aged 25-35.
(n=20 for each group, equal number of men and women).All participants had a background in using digital cameras and all spoke Hebrew at a mother tongue level.
The research methodology included the 3 following stages:
1. Questionnaire whose purpose was to provide a general picture of the participants.
2. Practical experience, each participant carried out 3 tasks that involved using the camera: taking 5 pictures, deleting a single picture and
deleting all the pictures from the camera’s memory. Each participant was given an overall grade for performance of these tasks.
3. Feedback form in which they reported about their impression of and ability to perform the tasks.
Results: Among the older group, there was a marked difficulty in understanding the new system. Beginning with the second task, they had not been able to retain the information given to them regarding the camera operation. There is a tendency among the older group to ask for help frequently from family members about camera operation and less to use the camera manual etc. The older group is less “active” in using the camera’s different functions. We also saw difficulty in identifying and understanding the icons on the various camera displays. We noted great difficulty in operating the main navigation control, especially in terms of precision of movement. It was found that the higher the level of users’ English, the higher the grade they received for task performance. Gender differences were found among the older group in regard to task performance; males received higher performance grades.
Conclusions: Creating a successful and productive digital camera user experience, suited to an older population, is a challenging task and it requires first and foremost the identification and acknowledgement of the abilities and limitations typical of this group in terms of their sensory, motoric and cognitive functioning, which can then be integrated into the camera’s system.
