What are the best ways to test prototypes for physical dexterity?

Any 'ideal' user experiences are in essence conducting maturity tests of a prototype. Knowing what to test is often as important as understanding the potential evolution of the product. For example, to test a new industrial controller, the maturity ladder for the controller could be: 1. Does its core job of controlling 2. Intuitive user experience to use 3. Ergonomically easy to use 4. Seamless integration within the existing system (I am of course hypothesizing here) Your tests for each step will be different as will the level of dexterity being tested with each step. However if you already have a product and want to test its dexterity then the goals - testing method - test- analyze - iterate - validate loop works just fine.

A very good thing to keep in mind UX haptics and usability is that you MUST always remember YOU will get older, slower, low vision, maybe with a motorial impairment…AND STILL you must use “your own” body and still make the thing readily usable. BEST technique other than getting expensive HW & SW metrics is what they teach in the military… place a bendage over one eye, tie one of your arms and try to actually USE your product… if you can still do most of the work then ok, you just need to add some shortcuts or specific provisions for them ( pop ups, extra voice menus, …)… HOWEVER if you CANNOT even do basic stuff then it’s time to start over…

This is a great article and the technical structure presented is sound and logically structured. For dexterity applications/designs (human interaction) I would recommend that ‘Customer Empathy’ be a core part of the design-test-fix process - particularly in an application like this one. This may be already included in the ‘goals’ section… if so, it would be prudent to consider having this important factor as a separate category. Great article!

Assuming the prototypes are ready to be tested, select a group of individuals from the target age group for which the actual product will be launched. These individuals should be picked up from different demographics within the age group with diverse experience. Preferred way is to send them the prototypes to their homes with all the instructions so they use the prototypes whenever they want and however they want. Send proper instructions along with the prototype and ask them to video tape the use of the prototype and even encourage them to provide input to further improve the usage of the prototype. Also their testing and usage of the prototypes should be for a set number of days and they should be asked to send their videos, etc. back.

The best ways to test physical dexterity prototypes involve conducting practical tests with representative users, assessing accuracy, speed, and comfort during use. When analyzing test results, identify areas for improvement, highlight strengths, and adjust the design as needed to optimize the user experience.

Here are effective ways to analyze test results: - Quantifiable measures such as completion times, error rates, and task success rates. - Detailed observations of users' interactions, gestures, and feedback. - How well users perform specific tasks that require physical dexterity. - Collected feedback through surveys, questionnaires, or interviews. - Compare test results with predefined dexterity goals and design specifications. - Heatmaps generated from user interactions. - User interaction patterns and frequently accessed areas. - Assess the impact of iterative changes on test results. - Insights provided by experts during evaluations. - Biomechanical data related to users' physical movements. - Identify trends related to usability aspects

Iterative Refinement involves a continuous enhancement process driven by insights gained from ongoing testing results. It emphasizes a cyclic approach to improve a product, system, or solution. By iteratively analyzing feedback and making adjustments, this method ensures a dynamic evolution that aligns with changing requirements and user needs. This perpetual refinement cycle fosters adaptability, allowing the enhancement of features, functionality, and performance over time, ultimately optimizing the end product based on real-time feedback and testing outcomes.

Comme toujours avant de tester, comme ici la dextérité, la première question est, qui est la cible? Et de fait quelles sont ses capacités de base et d'apprentissage ? La deuxième question est: est ce que je veux qualifier la dextérité ou savoir où je me situe vis à vis de la concurrence... une fois ces questions bien étudiées alors le protocole peut être mis en place. Maintenant au delà de ces deux aspects précisés ci-dessus, si le produit est pour Mr et Mme tout le monde, imaginons des produits pour des personnes à faibles dextérité, créons les avec cette limite physique et/ou neurologique et nos produits seront de fait, adapté au plus grand nombre... Ne faisons pas de l'handicap une exception mais la normalité pour une inclusion totale.
