GO LOKO
Evaluation
We designed and conducted usability tests for the designed application in two stages. We prepared pre test and post questionnaires to assist our testing processes and conducted tests with 2 patients and 1 therapist. Using the findings from the med fi prototype testing, we implemented changes for the high fidelity prototype and conducted another round of testing with 3 patients and 2 therapists.
Medium Fidelity Prototype
Evaluation
We conducted medium fidelity prototype with 2 patients and 1 therapist. We conducted these tests to understand if the users understand the idea of InnoMotion and if they are able to easily navigate through various features. These were few of our findings.
Patient 1 : “There is a problem understanding exercise instructions. It will be helpful to have images involved in instruction.”
Patient 2: “It is hard to click buttons because of the injury. So it would be better to have less buttons and have more hand gestures and voice command or other possible controls for Leap Motion.”
Therapist 1: “Want some additional space for notes on the exercises to give to patients.”
High Fidelity Prototype Evaluation
We conducted medium fidelity prototype with 3 patients and 2 therapists. These test were conducted to understand how users interacted with each feature and to see if they liked it or not. The idea was widely appreciated.
Patient 1: “I like that I can receive messages from my therapists; that
way I know I am doing the exercise right or wrong.”
Patient 2: “Real world target visualization tells me when I can actually
start doing my work like I used to. That is very helpful, It keeps me
motivated.”
Therapist 1: “Likes recommended exercises. Encourages patients to
work extra hard.”
Evaluation Process
Techniques and Methods
We mostly used questionnaires and think aloud methods for our usability analysis and tests.
Recruiting users
The user set of InnoMotion is well defined and hence people who have undergone therapy in teh previous 6 months and therapists were our target users for usability tests.
Process
The target user was given a pre questionnaire followed by a set of tasks to perform using innomotion. A post test questionnaire helped get a broder feedback on the product as a whole.
