Mentoring

Mentors should:

• Spend adequate time with their students

• Provide a space to work

• Be present at the two formal presentations and at the

SURF

• Deliver a Tuesday seminar talk and lead a Friday

Update.


Mentoring

• If the mentor travels during the program, he/she has

to assign another mentor in his/her research group,

who is familiar with the participant’s project, such as

a graduate student, postdoc, or other faculty

member.

• Mentors are invited to all academic, cultural, and

social activities in which the students participate.


Surveys

• CCT Students:

– Start and end of program, a La Carte survey

– From the NSF CISE, nationwide, based at UNC

• Longitudinal: keep in touch

• Mentors will fill out surveys, too!

Enhancing Tangible Tokens Through Additive Manufacturing and Capacitive Sensing

Tokens are physical artifacts that serve as a tangible

depiction of an object, place or emotion. Tokens are items

typically used to access information, everyday tokens are

credit cards or board game pieces.

These tokens operate the poster by acting as an

intermediate between a tablet and personal computer.

Revolving a token can transition through the poster’s

pages, among other functions. Tangibles tokens have even

been shown to develop participation and attraction in

museums.

Introduc) on Results

Additive manufacturing (3D-printing) is a mechanical process that generates a

three-dimensional body. This is done by “slicing” the virtual model into two-

dimensional segments and then printing the actual object layer by layer. Nearly any

model of distinct geometry or shape can be constructed by way of

additive manufacturing.

The tokens for this project were constructed from three different 3D printers: the

Lulzbot, Makerbot, and Voxel8.

This material is based upon work supported by the National Science

Foundation under award OCI-1560410 with additional support from the

Center for Computation & Technology at Louisiana State University

Figure 5: Solidworks

Figure 9: Musical Token

Fabricating a token requires a source 3D model. To design the tokens I primarily

used Solidworks, a solid modeling program. Building the model requires an

analysis of the geometry of the intended shape as well as awareness of the units of

the design. Once the model is finished it is imported into a machine’s respective 3D

print preparation software, ready to be produced.

The previous acrylic design yielded

several issues. Some included: • Number of materials

• Complexity

• Convenience

As shown in Figure 4, the amount

of materials needed to construct an

acrylic token are substantial

relative to the 3D printed

counterpart (19 vs. 4, respectively).

All pieces to the acrylic token must

manually assembled.

A 3D printed token requires no

external tools, and can be printed

on-site within an hour. The level of

complexity to a 3D printed token’s

design is limited to that of one’s 3D

printer and CAD (Computer Aided

Drafting) skills.

Once an elementary design for a

3D printed token was achieved, the

next purpose was to add additional

features to the token.

Vibrotactile Token

Configurable Token

Musical Token

By augmenting these tokens, connections between

content and their audience may greatly increase.

tokens that this research is concerned with are those

that navigate interactive posters, specifically the

Entrada platform. This project’s approach is to

enhance the previous design of a token by facilitating

feedback, altering the materials, and extending the

medium in which they are produced.

Lulzbot Makerbot Voxel8

Despite the positive outcomes, there are caveats to 3D printing. Although a

user may print onsite, they must still wait one to two hours for the

fabrication to complete. Printing filament also deviates between printers.

The Makerbot seamlessly extrudes ABS, but is lackluster in regards to

printing PLA. With the Lulzbot, when printing material that is not

conductive PLA, its support structures (scaffolding that holds the print in

place) are rigid and difficult to remove.

Figure 2: The Entrada platform

for digital posters

For this prototype, the motivation is to incorporate a feedback

system onto the tokens. Placed in the center of the tangible is a

permanent magnet. The magnet’s purpose is to reverberate the

token, producing haptic feedback. The magnet’s vibration is a

result from the electromagnetic field generated by the system in

Figure 6. The token must be in close proximity to this structure

for the feedback to be felt. Other conditions, such as the token’s

weight and the strength of the electromagnetic field, also affect

the presence of haptic feedback.

The configurable token is designed to incorporate a more

advanced tangible, or “smart” token. For instance, the token is

built to house an Arduino monitor (Fig. 7). It also consists of

several other components (Fig. 8), including a gesture sensor.

Upon placing the piece onto a colored surface this sensor will

react to a pigment, prompting an actively mediated response

from the integrated display surface.

The Musical Token was constructed by the Voxel8, which

prints both nonconductive and conductive materials. For

this token, the wiring serves as a capacitive-sensing factor.

Erecting from Fig. 9 is an edge connector which is tethered

to a Raspberry Pi. Upon touching different locations along

the sides, different a musical notes are played. While this

token does not function with the poster, it does serve as a

precursor to more advanced token capabilities.

Figure 10: Musical

Token set-up

Figure 6: Vibrotactile

token set-up

The filaments used to create the tokens were

two plastics, ABS (Acrylonitrile Butadiene

Styrene) and conductive PLA (Polylactic

Acid). Conductive PLA facilitates capacitive

sensing, allowing our tokens to realize digital

functions (e.g., navigating a digital poster).

ABS became useful for design as an

economical, complementary medium to our

use of functional conductive PLA.

For our tokens to further progress, we envision: • Extending the token’s feedback mechanisms;

• Construct an active token from the Voxel8 which requires no

outside wiring labor; • Explore alternative designs to the current knob/dial, like

composition exhibited by the token; • Consider some method, possibly using a rotary tumbler, to polish

or blend the token’s additive layers.
