Some more interesting changes to Iteration 2 after another user test with Arthur! It is coming together nicely.
Dissecting a user test – how we improve!
Each user test is an exciting event. Each user test throws up at least half a dozen “aha” or “why didn’t I think of that” moments, driving on and further inspiring development. In our most recent user test (yesterday evening with Mr R) there were some obvious but useful minor improvements we could make to…
Why is designing EyeSkills difficult? – a quick note
When building software, one is creating a simplified model of reality, capturing those parts which are relevant to achieving the system goals. This model is not generally not built to be passive, it should then interact with reality to alter the nature of reality. It’s an interesting feedback loop called “active modelling”. If we don’t…
First test of second iteration with Mr. R
What a wonderful test. Mr R has alternating strabismus, and a very strong suppression. The Binocular Suppression scene is now designed well enough that it not only demonstrates the suppression switching on very well (by introducing conflict), but allows us to find that breakthrough point where – despite the suppression – Mr R can see…
EyeSkills Prototype for Lazy Eye – Iteration 2 – Practitioner View
A first quick look at how the second iteration of the open-source EyeSkills prototype works. This prototype is designed to test the visual abilities of a person with Lazy Eye, and evaluate the effectiveness of a few techniques which may be useful in allowing a participant to re-establish binocular vision.
Free code! TTS and Device Gestures.
I’m going to throw a few snippets of code in here that are coming out of the current sprint, because they are generally useful. I’ll also spend a few minutes commenting what’s happening so that non-unity/C-Sharp developers can start to get a feel for it…. The snippets are code for easily generating offline Text-To-Speech and…
Iteration 2 – Migrations
Migrations Aspect 1 – Demonstrating the impossible is possible – Guided – Verifying abilities Our user tests established the validity of checking and exploring the visual abilities of a participant in the following order:
Iteration 2 – Motivation
Motivation We have identified four underlying motivations for the project. Whilst these build atop one another, we try to isolate them conceptually to help us manage our limited development resources.
Iteration 2 – Concepts
Concepts In Iteration 1 we had a participant flow which went through a series of calibration scenes covering different aspects of vision (e.g. Monocular vision present? Biocular vision? Depth perception?…). These scenes were originally focused on building up a calibration object which could describe the participants visual abilities, to then calibrate the “main” part of the…
Iteration 2 – Architectural changes to the framework.
This is an open design document, explaining the rational behind the evolution of the framework. With more experience and evidence, many of these elements may change in unpredictable ways – it is a work-in-progress. Previously:
