World’s first automated motor skill test – exploiting the power of touch tablets

Results presented at Ubicomp 2016, Heidelberg, Germany

Knowledge and cognitive ability tests have been automated and are taken on computers for more than three decades now. Pretty much all of you would have taken a SAT, GMAT or a GRE. What about motor skills? They are needed for almost all vocational jobs, say a plumber’s manual dexterity in fixing a screw. The best tests for them still are these bulky boards, pegs and instruments.

No one till date really thought about exploiting the power of the touch interfaces to develop such tests. Touch screen based devices are now ubiquitous in form of mobile phones and tablets. We wanted to find whether we can test people’s skills, say in tailoring and machining, by making them do things on the tablet. We wrote creative apps to make them do various actions on a tablet — rotating their fingers, pinching them, moving their elbows and shoulders to trace… and so on.

We reported in our Ubicomp paper, presented last week, that the scores from these tests actually do predict the speed and accuracy of industrial tasks done by machinists, tailors and machine operators. In fact, they are better predictors than the bulky manual tests! Our test scores can predict all parameters of task performance measured by us. The correlation ranges 0.19 to 0.37, similar to what a logical ability test would predict for a knowledge worker. In comparison, manual test scores correlate significantly only for 4 out of 7 task performance ratings and ranges 0.19-0.33.

This has great implications for the training and job matching of vocational workers. Using these apps, vocational job aspirants can test their motor skills at the comfort of their homes. They can get feedback and work on improving their skills. Also, if they perform well, they can generate credentials such as “Motor skills certified for a tailor” and highlight them to employers. The same assessments can be used by the industry to filter and recruit high performing employees.

We are happy to present the world’s first validated motor skill test. There is so much more opportunity for further research – figuring out which scores correlate to performance in which task, creating a job to score map, creating more innovative apps and so on… Let us do it with the power of the touch interface.


The first interactive US Skill Demand Map- A big data approach

Jobseekers wish to know what skills are required by the industry in their region and also, what skills pay the most. So do institutions of higher and vocational education. Unfortunately, there is no information about this. It is considered hard to collate such information and the old school way of running surveys with corporations is time-consuming, expensive and mired by subjectivity.

We went after this problem the big data way – we scrapped some 4 million job openings from the web for the US, automatically matched them to our taxonomy of 1064 job roles and the 200+ skills required for these job roles. What did we get out of this? The US Skill Demand Map – For each state in the US, we know what percent of open jobs require a given skill and how much does a skill pay. For instance, see the Heat Map below — it shows how much does the software engineering skill pays in different US states.  All this is generated automatically and be updated in minutes every month based on the current open jobs in the market!

This map is interactive. A jobseeker can enter his key skill to find which states demand it the most and which states pay for it the most. Additionally, s/he can scroll across the map to find the demand/compensation in each state for a given skill. On the other hand, the candidate can enter a state and find out top paying and high-demand skills in the state. Try it now!

Such analysis also helps us uncover policy trends (See our report). We found that agreeableness and finger dexterity are the most in demand skills after Information Gathering and Synthesis, which has the highest demand. One may see in the map below the states which have more percent of jobs requiring agreeableness and those where finger dexterity is required more often.


Figure 2: Skills in highest demand in each U.S. state (other than Information Gathering & Synthesis)

On the other hand, we can find the states which have the most demand and pay the most for say, analytical skills. New York pays the most for the skill, whereas the highest percent of jobs in Virginia need analytical skills. (See Figure 3)

Figure 3: Heat maps for demand and compensation for analytical skills

The U.S. Skill Demand Map fills a major information gap in the labor market. To our knowledge, this is the first effort to objectively present the demand for skills across US states to aid better decision-making by job seekers. It is based on objective data, it is quick, accurate and user-friendly.

Scaling up machine learning to grade computer programs for 1000s of questions in multiple languages

Machine learning has helped solved many grading challenges – spoken english, essay grading, program grading and math problem grading to cite a few examples. However, there is a big impedance in using these methods in real world settings. This is because one needs to build an ML model for every question/prompt – for instance, in essay grading, a different model designed to grade an essay on ‘Socialism’ will be very different from one which can grade essays on ‘Theatre’. These models require a large number of expert rated samples and a fresh model building exercise each time. A real-world practical assessment works on 100s of questions which then translates to requiring 100s of graders and 100s of models. The approach doesn’t yield to be scalable, takes too much time and most of the times, is impractical.

In our KDD paper accepted today, we solve this challenge quite a bit for grading computer programs. In KDD 2014, we had presented the first machine learning approach to grade computer programs, but we had to build a model per problem. We have now invented a technique where we need no expert graded samples for a new problem and we don’t need to build any new models! As soon as we have around a few tens of ‘good’ codes for a problem (automatically identified using test case coverage and static analysis), our newly invented question-agnostic models automatically take charge. How will this help us? With this technology, our machine learning based models can scale, in an automated way, to grade 1000s of questions in multiple languages in a really short span of time. Within a couple of weeks of a new question being introduced into our question pool, the machine learning evaluation kicks in.

There were couple of innovations which led to this work, a semi-supervised approach to model building:

  • We can identify a subset of the ‘good’ set automatically. In the case of programs, the ‘good set’, codes which get a high grade, can be identified automatically using test cases. We exploit this to find other programs similar to these in a feature space that we define. To get a sense of this, think of a distance measure from programs identified as part of the ‘good set’. Such a ‘nearness’ feature would then correlate with grades across questions irrespective of whether it is a binary search problem or a tree traversal problem. Such features help us build generic models across questions.

  • We design a number of such features which are invariant to the question and correlate to the expert grade. These features are inspired by the grammar we proposed in our earlier work. For instance, one feature is how different is an unseen program from the set of keywords present in the ‘good set’; while another is the difference in the programs in the kind of computations they are doing. Using such features, we learn generic models for a set of problems using supervised learning. These generic models work super well for any new problem as soon as we get our set of good codes!

Check out this illustrative and easy-to-grasp video which demonstrates our latest innovation.


The table presents a snapshot of the results presented in the paper. As shown in the last two columns, the ‘question-independent’ machine learning model (ML Model) constantly outperforms the test suite based baseline (Baseline). The claim of ‘question-independence’ is corroborated by similar and encouraging results (depicted in last three rows) obtained on totally unseen questions, which were not used to train the model.

Question Set
ML Model
All questions
All questions
All questions
Unseen questions only

What does this all mean?

  • We can really scale ML based grading of computer programs. We can continue to add new problems and the models will automatically start working within a couple of weeks.
  • These set of innovations apply to a number of other problems where we can automatically identify a good set. For instance, in circuit solving problems, the ones with the correct final answer could be considered a good set; this can similarly be applied to mathematics problems or an automata design problem; problems where computer science techniques are mature to verify functional correctness of a solution. Machine learning can automatically then help grade other unseen responses using this information.

Hoping to see more and more ML applied to grading!

An Automated Test of Motor Skills for Job Prediction and Feedback

We’re pleased to announce that our recent work on designing automated assessments to test motor skills (skills like finger dexterity and wrist dexterity) has been accepted for publication at the 9th International Conference on Educational Data Mining (EDM 2016).
Here are some highlights of our work –

  • The need: Motor skills are required in a large number of blue collar jobs today. However, no automated means exist to test and provide feedback on these skills. We explore the use of touch-screen surfaces and tablet-apps to measure these skills.
  • Gamified apps: We design novel app-based gamified tests to measure one’s motor skills. We’ve designed apps to specifically check finger dexterity, manual dexterity and multilimb co-ordination.









  • Validation on three jobs: We validated the scores from the apps on three different job roles – tailoring, plumbing and carpentry. The results we present make a strong case for using such automated, touch-screen based tests in job selection and to provide automatic feedback for test-takers to improve their skills!
