Agenda

• Project Review• EDIT 732: Prototype version 1.0• Research: Round 1• Changes: Prototype version 2.0• Research: Round 2• Changes: Prototype version 3.0• Business Model Update• Summary

Project Review• AR Chemistry Lab for home school high school Chemistry students

• Students would use AR based lab to replace existing labs that are conducted at home using basic lab materials and off-the-shelf curriculums (e.g. Apologia)

• Advantage of AR labs: safe, inexpensive, logistics friendly, student centered/controlled, spatial oriented, physical component (haptic), exploratory in nature, meets CLEP standards, and allows for easy iterative modeling.

Project Review• Primary Persona: HS junior - college-bound, independent learner, wants

enriching learning experiences, frustrated by lab barriers, open to new technology, and life long learner.

• Secondary Persona: Parent/teacher - Safety/time/dollar conscious, preparing kids to compete and excel in college and be lifelong learners.

• Warrants further investigation and review at a future date

EDIT 732: Prototype version 1.0• Captivate concept based prototype• Focused on:

– Reaction time and pour rate calculations of AR algorithm in order to replicate realistic titration experience

– Parent Control– CLEP– Using water, flour, and house hold cups– Stick, Cut, Place in Front

Research: Round 1 (March 2011)• Three components:

– Critical Group Reflection (CGR)– Competitive Analysis– Interviews: 4 interviews(3 students/1 parent/teacher)

• Findings– CGR:

• Use beakers instead of cups based on feedback from stakeholders

• Need to have a weight component for powders

• Creation of Research Questions– Competitive Analysis:

• Still no competitors, but…

Research: Round 1 (March 2011)• Findings (continued):

– Interviews (4)• Format/ HSRB approved• Feedback:

– Validation of key concepts/assumptions identified in CGR

» Validated: Concept, Safety, logistics, CLEP, modeling, realistic, constructivist, price (value)

» Not Validated: sharing results with siblings, marketing slogan, value of using household items, simplicity over reality

– Measurement must be done and errors must impact the outcome in a realistic way

– Measurement tools should be realistic– User controls/options fine-tuned

Research: Round 1 (March 2011)• Process for Revising the Prototype

– Group 2 developed a table that includes:• A description of each prototype item we

evaluated• What action we took with the item in our

revised prototype• What category type(s) does each

prototype item belong to (Functional, Operational, Visual, Marketing, and Standards)

• The source(s) who noted the prototype item

• The group’s decision and logic to why we took the action we did with the item in the revised prototype

Round 1

Description/Item Action Type ( function/operation/Visual etc)

Source Decision/point logic

Household glasses Delete Functional and Standards Feedback from Yohan/ 1st interview student (Tim – 16YO) and 3rd interview student (Lisa 20YO)

In order to practice realistic lab measurements real beakers are required. Provides an authentic haptic experience with appropriate size beakers.

Sharing results with siblings

Delete Marketing Feedback from Tim and Lisa

Realistically would not share the results with sibling

Marketing slogan:“print/cut/stick in front”

Delete Marketing Feedback from Tim “sounds like Staples”. No longer relevant since switching to permanent universal markers on beaker kit

Business Feasibility of prototype

Retain Marketing to Stakeholder Competitive Analysis and Interview w/ Sally

Updated competitive analysis performed independently by 2 group members showed there is still no current competitors in offering a AR Chemistry lab. However, other non-lab based AR science products are entering the market (e.g. geology). Based on interview with Sally and price analysis of current science based AR products a realistic price point for our AR Chemistry lab might be $250.

Round 1



Ease of use and value of using household materials over real chemicals

Retain Standards, Functional, and Operational

Feedback from 1st interview parent (Sally), Tim, Lisa, and Kesha (2nd interview student -17YO)

all confirmed it is difficult at times to get certain chemicals (including exotic house hold cleaners), so using basic house hold materials (e.g. water) would be much easier

Borders components: voice command, hint, explore, description of smell, touch, sight/alert error

Modified Functional, Operational, Visual, and Standards

Tim, Lisa, Kesha Add (Tim/Lisa/Kesha): voice command to allow hands free timing of experiments; Add (Tim/Lisa): hint button to allow f/u if lab errors made; Add(Tim): explore button to perform additional exploratory based functions such as adding elements together to form new molecules; Add (Lisa/Kesha): Description (Alert error) of reaction smell, touch, see to make reaction more realistic

Temperature displays (Authentic look and capable of Kelvin, Calvin, Fahrenheit)

Modified Functional and Visual Lisa added ability to switch between Kelvin, Celsius, and F…based on Lisa's suggestion that certain labs would use different measurements standards. Increased authentic experience

Round 1



Beakers Added Standards, Functional and Operational

Feedback from Yohan/ 1st interview student (Tim - 16YO) and 3rd interview student (Lisa 20YO)

In order to practice realistic lab measurements real beakers are required. Provides an authentic haptic experience with appropriate size beakers.

Universal markers etched on beakers

Added Standards, Functional and Operational

Critical Group Reflection In order to simplify the process (no more print/cut/stick in front) and make it easier for the computer to read the marker. It will also allow for more accurate calculation by the computer)

Lab equipment Added Standards, Functional and Operational

Critical Group Reflection and Sally, Tim, Lisa, and Kesha

We realized from the feedback and through reflection that using lab equipment would be more realistic in the context of a chemistry lab and providing the learners a more authentic haptic experience

Mac or PC Added Operational Interview w/ Tim Tim pointed out that most of his friends had Macs and having a learning system that was compatible with either a Mac or PC was important

Round 1



Record, play, REW/FWD, pause

Added Functional and Operational

Interview w/ Tim and Lisa Tim and Lisa thought it would be important to be able to record and then rewind and watch certain segments of lab either to study or to fix mistakes.

Ability to purchase individual lab(s)

Added Functional Sally Sally suggested it would be nice to have the option to buy whatever lab you needed.

Salt instead of flour Added Operational Critical Group Reflection We realized that flour would congeal in water and add significant weight. Salt would still allow the mixing of a substance into the liquid (water), but would add negligible weight.

Round 1



Measurement capabilities Added Standards, Functional, and Operational

Lisa and Kesha Both identified the importance of measuring in a lab. Lisa identified importance of having measuring errors detected by the program. Kesha thought it would be beneficial to see what happens if you do something wrong. Therefore in our prototype we will demonstrate a measurement error result in a bubbling over effect (large amount of vinegar/baking soda) and only slight blue color change.

Round 1



Scale Added Standards, Functional and Operational

Critical Group Reflection We realize to insure proper measurements of liquid and to provide additional measurement experience (e.g. powders) for the students a digital scale would be required. The beaker receiving the water is placed on the scale, and as the water is poured in (e.g. 50mL) the computer would detect the exact weight and correlate this with exact volume. Any error would result in a authentic reaction in the actual AR simulated lab results..

Add 3-D Model of Chemical Reaction

Add Functional, Operational, Visual, and Standard

Tim Add real-time change of the 3D structures as they are mixed.

View field Refined Functional and Visual Tim Suggested that a view plane should allow the user to put the 3D modeled chemical structure on the side of the experiment viewing area and watch the real-time change of the 3D structures as they are mixed.

Round 1



Expanded scope of the chemical reactions in the lab

Refined Standards, Functional, and Operational

Lisa Lisa suggested that experiments were more interesting with fizz/steam rather than just a color change. Therefore, our correct chemical reaction experiment will not only change to blue color, but also have a slight bubbling (i.e.. small amount of baking soda/vinegar)

Safety is a default Refined Standards and Functional Sally, Tim, Lisa, and Kesha

all agreed that safety was an important affordance of this AR simulated lab. Therefore, we decided that the safety feature would be set by default.

CLEP Retain Standards Sally, Tim, Lisa, and Kesha

all agreed that the curriculum preparing the student for a CLEP test is a valuable feature
