Planning

Week 2 (16 Dec - 22 Dec):

Task	Person responsible	Deadline	Remarks	Done
Creating planning	Everyone	14-02-2019
Researching different materials: Making a overview of different materials based on multiple aspects such as cost, smoothness, stretchability or other factors which could be important.	Dennis	20-02-2019		Needs to add the references and finish small parts. Will be done before the tutor meeting
Getting blind contacts, make appointment and creating a survey.	Luc	20-02-2019	Appointment date doesn’t have to be within the deadline	Didn’t create survey
Working out existing Braille mechanism solutions for six-dot cells and argue their (cost)effectiveness	Thomas	20-02-2019	Piezo-electro Electro-magnets Motor per pin
Creating system/process of taking .pdf text input and outputting Braille	Dirk	20-02-2019	Requires documentation First output to plain text and then to Braille
Look for possibilities of creating Windows program that outputs to Arduino	Simon	20-02-2019	Requires documentation on choices made
Discuss the survey contents	Everyone	20-02-2019		Content finished during meeting

Week 3 (23 Dec - 29 Dec):

Task	Person responsible	Deadline	Remarks	done
Word context to Braille shortcuts recognition	Dirk	27-02-2019	Optimization of .pdf to Braille system	Optional function
Finish survey layout and give it to our target group.	Luc	27-02-2019	Or interview them depending on the appointment	No response from contacts
Define the user requirements based on the results of the survey.	Everyone	27-02-2019	First iteration of the user requirements
Defining the Braille mechanism	Luc	27-02-2019	Blueprint of how it should be constructed	Needs some changes
Specifying the parts and create circuit diagram	Thomas	27-02-2019	Includes calculations electricity usage and resistors
Defining the output of Arduino to the Braille mechanism	Simon	27-02-2019	How to let the Arduino work correctly with the mechanism i.e. reversing polarity
Creating user interface concept with the current user requirements	Thomas	04-03-2019	This date may change depending on the user requirements	No survey conducted
Choose and get the best material(s) and look into how to make a suitable dummy Braille.	Dennis	27-02-2019	Best materials will be based on the research and based of off multiple perspectives (such as cost, smoothness and stretchability)
Buying the components	Everyone	27-02-2019	Will be done during the meeting	Components not definitive

Week 4 (29 Dec - 5 Jan):

Task	Person responsible	Deadline	Remarks	Done
Attempt to get in touch with contact person again	Luc	13-02-2019		Two surveys completed, no further contact responses
Change Braille mechanism and make model of it	Luc	13-02-2019	Mechanism consists of cam follower with solenoid now
Guess the user requirements and create a user interface for it	Thomas	13-02-2019	Base the user requirements on educated guesses with the literature study
Testing the entire software with Arduino output	Simon & Dirk	13-02-2019		Will be done later in the afternoon
Testing a solenoid	Simon	13-02-2019		Failed test, will retry with transistor connection check
Creating different dummies to test usability without the material.	Dennis & Thomas & Dirk & Simon	13-02-2019	Solid materials (aluminium, plastic, etc)	3D model being worked on to be printed

 

Week 5 (5 Jan - 13 Jan):

Recreate 3D model with cam follower mechanism	Luc	20-03-2019	Updated pin dimensions
Getting the materials for the dummy and write about braille pin distance interpretation	Dennis	20-03-2019	Human fingers have can distinguish for example 2mm and the arm like 2cm? What research lies behind the standard braille distances we have and explain them a bit for argumentation of the design decision
