Question 11

The human interfaces for each of the various technologies are different and can even differ among different brands or versions of the same device.

Question 12

Current telehealth technologies are focused on clinicians being able to see patients and not interact with them since audio and streaming video capabilities are costly.

Question 13

Three axioms have evolved for developing effective human-computer interactions: (1) Users must be an early and continuous focus during interface design; (2) the design process should be iterative, allowing for evaluation and correction of identified problems; and (3) formal evaluation should take place using rigorous experimental or qualitative methods.

Question 14

Human-technology interface problems are the major cause of all patient monitoring incidents. It is not always that the technology itself is faulty. In fact, the technology may perform flawlessly, but the interface design may cause human error.

Question 15

Clinical and educational interfaces have moved away from using tactile input.

Question 16

Developers must focus on users immediately after the interface is designed.

Question 17

The design process should be iterative, allowing for evaluation and correction of identified problems.

Question 18

Task analysis examines how a task must be accomplished.

Question 19

Cognitive task analysis usually starts by identifying, through interviews or questionnaires, the particular task and its typicality and frequency.

Question 20

Little can be learned from the related field of cognitive engineering about how to make interfaces more compatible with their human users and the context of care.
